  • Pregnancy week by week
  • Fetal presentation before birth

The way a baby is positioned in the uterus just before birth can have a big effect on labor and delivery. This positioning is called fetal presentation.

Babies twist, stretch and tumble quite a bit during pregnancy. Before labor starts, however, they usually come to rest in a way that allows them to be delivered through the birth canal headfirst. This position is called cephalic presentation. But there are other ways a baby may settle just before labor begins.

Following are some of the possible ways a baby may be positioned at the end of pregnancy.

Head down, face down

When a baby is head down, face down, the medical term for it is the cephalic occiput anterior position. This the most common position for a baby to be born in. With the face down and turned slightly to the side, the smallest part of the baby's head leads the way through the birth canal. It is the easiest way for a baby to be born.

Head down, face up

When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.

Most babies who begin labor in this position eventually turn to be face down. If that doesn't happen, and the second stage of labor is taking a long time, a member of the health care team may reach through the vagina to help the baby turn. This is called manual rotation.

In some cases, a baby can be born in the head-down, face-up position. Use of forceps or a vacuum device to help with delivery is more common when a baby is in this position than in the head-down, face-down position. In some cases, a C-section delivery may be needed.

Frank breech

When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head. This is the most common type of breech presentation.

If you are more than 36 weeks into your pregnancy and your baby is in a frank breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Most babies in a frank breech position are born by planned C-section.

Complete and incomplete breech

A complete breech presentation, as shown below, is when the baby has both knees bent and both legs pulled close to the body. In an incomplete breech, one or both of the legs are not pulled close to the body, and one or both of the feet or knees are below the baby's buttocks. If a baby is in either of these positions, you might feel kicking in the lower part of your belly.

If you are more than 36 weeks into your pregnancy and your baby is in a complete or incomplete breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Many babies in a complete or incomplete breech position are born by planned C-section.

Illustration of a complete breech presentation

When a baby is sideways — lying horizontal across the uterus, rather than vertical — it's called a transverse lie. In this position, the baby's back might be:

  • Down, with the back facing the birth canal.
  • Sideways, with one shoulder pointing toward the birth canal.
  • Up, with the hands and feet facing the birth canal.

Although many babies are sideways early in pregnancy, few stay this way when labor begins.

If your baby is in a transverse lie during week 37 of your pregnancy, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of your health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a transverse lie, talk with a member of your health care team about the choices you have for delivery. Many babies who are in a transverse lie are born by C-section.

Illustration of baby lying sideways

If you're pregnant with twins and only the twin that's lower in the uterus is head down, as shown below, your health care provider may first deliver that baby vaginally.

Then, in some cases, your health care team may suggest delivering the second twin in the breech position. Or they may try to move the second twin into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

Your health care team may suggest delivery by C-section for the second twin if:

  • An attempt to deliver the baby in the breech position is not successful.
  • You do not want to try to have the baby delivered vaginally in the breech position.
  • An attempt to move the baby into a head-down position is not successful.
  • You do not want to try to move the baby to a head-down position.

In some cases, your health care team may advise that you have both twins delivered by C-section. That might happen if the lower twin is not head down, the second twin has low or high birth weight as compared to the first twin, or if preterm labor starts.

Breech, posterior, transverse lie: What position is my baby in?

Layan Alrahmani, M.D.

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. At the time of delivery, 97 percent of babies are head-down (cephalic presentation). But there are several other possibilities, including feet or bottom first (breech) as well as sideways (transverse lie) and diagonal (oblique lie).

Fetal presentation and position

During the last trimester of your pregnancy, your provider will check your baby's presentation by feeling your belly to locate the head, bottom, and back. If it's unclear, your provider may do an ultrasound or an internal exam to feel what part of the baby is in your pelvis.

Fetal position refers to whether the baby is facing your spine (anterior position) or facing your belly (posterior position). Fetal position can change often: Your baby may be face up at the beginning of labor and face down at delivery.

Here are the many possibilities for fetal presentation and position in the womb.

Medical illustrations by Jonathan Dimes

Head down, facing down (anterior position)

A baby who is head down and facing your spine is in the anterior position. This is the most common fetal presentation and the easiest position for a vaginal delivery.

This position is also known as "occiput anterior" because the back of your baby's skull (occipital bone) is in the front (anterior) of your pelvis.

Head down, facing up (posterior position)

In the posterior position , your baby is head down and facing your belly. You may also hear it called "sunny-side up" because babies who stay in this position are born facing up. But many babies who are facing up during labor rotate to the easier face down (anterior) position before birth.

Posterior position is formally known as "occiput posterior" because the back of your baby's skull (occipital bone) is in the back (posterior) of your pelvis.

Frank breech

In the frank breech presentation, both the baby's legs are extended so that the feet are up near the face. This is the most common type of breech presentation. Breech babies are difficult to deliver vaginally, so most arrive by c-section .

Some providers will attempt to turn your baby manually to the head down position by applying pressure to your belly. This is called an external cephalic version , and it has a 58 percent success rate for turning breech babies. For more information, see our article on breech birth .

Complete breech

A complete breech is when your baby is bottom down with hips and knees bent in a tuck or cross-legged position. If your baby is in a complete breech, you may feel kicking in your lower abdomen.

Incomplete breech

In an incomplete breech, one of the baby's knees is bent so that the foot is tucked next to the bottom with the other leg extended, positioning that foot closer to the face.

Single footling breech

In the single footling breech presentation, one of the baby's feet is pointed toward your cervix.

Double footling breech

In the double footling breech presentation, both of the baby's feet are pointed toward your cervix.

Transverse lie

In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than 1 percent of the time, but it happens more commonly if you're carrying multiples or deliver before your due date.

If your baby stays in a transverse lie until the end of your pregnancy, it can be dangerous for delivery. Your provider will likely schedule a c-section or attempt an external cephalic version , which is highly successful for turning babies in this position.

Oblique lie

In rare cases, your baby may lie diagonally in your uterus, with his rump facing the side of your body at an angle.

Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie at the end of your third trimester.

The lie, presentation and position of a fetus are important during labour and delivery.

In this article, we will look at the risk factors, examination and management of abnormal fetal lie, malpresentation and malposition.

Definitions

  • Longitudinal, transverse or oblique
  • Cephalic vertex presentation is the most common and is considered the safest
  • Other presentations include breech, shoulder, face and brow
  • Usually the fetal head engages in the occipito-anterior position (the fetal occiput facing anteriorly) – this is ideal for birth
  • Other positions include occipito-posterior and occipito-transverse.

Note: Breech presentation is the most common malpresentation, and is covered in detail here .

what is presentation in pregnancy

Fig 1 – The two most common fetal presentations: cephalic and breech.

Risk Factors

The risk factors for abnormal fetal lie, malpresentation and malposition include:

  • Multiple pregnancy
  • Uterine abnormalities (e.g fibroids, partial septate uterus)
  • Fetal abnormalities
  • Placenta praevia
  • Primiparity

Identifying Fetal Lie, Presentation and Position

The fetal lie and presentation can usually be identified via abdominal examination. The fetal position is ascertained by vaginal examination.

For more information on the obstetric examination, see here .

  • Face the patient’s head
  • Place your hands on either side of the uterus and gently apply pressure; one side will feel fuller and firmer – this is the back, and fetal limbs may feel ‘knobbly’ on the opposite side

Presentation

  • Palpate the lower uterus (above the symphysis pubis) with the fingers of both hands; the head feels hard and round (cephalic) and the bottom feels soft and triangular (breech)
  • You may be able to gently push the fetal head from side to side

The fetal lie and presentation may not be possible to identify if the mother has a high BMI, if she has not emptied her bladder, if the fetus is small or if there is polyhydramnios .

During labour, vaginal examination is used to assess the position of the fetal head (in a cephalic vertex presentation). The landmarks of the fetal head, including the anterior and posterior fontanelles, indicate the position.

Fig 2 – Assessing fetal lie and presentation.

Investigations

Any suspected abnormal fetal lie or malpresentation should be confirmed by an ultrasound scan . This could also demonstrate predisposing uterine or fetal abnormalities.

Abnormal Fetal Lie

If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted – ideally between 36 and 38 weeks gestation.

ECV is the manipulation of the fetus to a cephalic presentation through the maternal abdomen.

It has an approximate success rate of 50% in primiparous women and 60% in multiparous women. Only 8% of breech presentations will spontaneously revert to cephalic in primiparous women over 36 weeks gestation.

Complications of ECV are rare but include fetal distress , premature rupture of membranes, antepartum haemorrhage (APH) and placental abruption. The risk of an emergency caesarean section (C-section) within 24 hours is around 1 in 200.

ECV is contraindicated in women with a recent APH, ruptured membranes, uterine abnormalities or a previous C-section .

what is presentation in pregnancy

Fig 3 – External cephalic version.

Malpresentation

The management of malpresentation is dependent on the presentation.

  • Breech – attempt ECV before labour, vaginal breech delivery or C-section
  • Brow – a C-section is necessary
  • If the chin is anterior (mento-anterior) a normal labour is possible; however, it is likely to be prolonged and there is an increased risk of a C-section being required
  • If the chin is posterior (mento-posterior) then a C-section is necessary
  • Shoulder – a C-section is necessary

Malposition

90% of malpositions spontaneously rotate to occipito-anterior as labour progresses. If the fetal head does not rotate, rotation and operative vaginal delivery can be attempted. Alternatively a C-section can be performed.

  • Usually the fetal head engages in the occipito-anterior position (the fetal occiput facing anteriorly) - this is ideal for birth

If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted - ideally between 36 and 38 weeks gestation.

  • Breech - attempt ECV before labour, vaginal breech delivery or C-section

Fetal Positions for Labor and Birth

Knowing your baby's position can you help ease pain and speed up labor

In the last weeks of pregnancy , determining your baby's position can help you manage pain and discomfort. Knowing your baby's position during early labor can help you adjust your own position during labor and possibly even speed up the process.

Right or Left Occiput Anterior

Illustration by JR Bee, Verywell 

Looking at where the baby's head is in the birth canal helps determine the fetal position.The front of a baby's head is referred to as the anterior portion and the back is the posterior portion. There are two different positions called occiput anterior (OA) positions that may occur.

The left occiput anterior (LOA) position is the most common in labor. In this position, the baby's head is slightly off-center in the pelvis with the back of the head toward the mother's left thigh.

The right occiput anterior (ROA) presentation is also common in labor. In this position, the back of the baby is slightly off-center in the pelvis with the back of the head toward the mother's right thigh.

In general, OA positions do not lead to problems or additional pain during labor or birth.  

Right or Left Occiput Transverse

Illustration by JR Bee, Verywell  

When facing out toward the mother's right thigh, the baby is said to be left occiput transverse (LOT). This position is halfway between a posterior and anterior position. If the baby was previously in a posterior position (in either direction), the LOT position indicates positive movement toward an anterior position.

When the baby is facing outward toward the mother's left thigh, the baby is said to be right occiput transverse (ROT). Like the previous presentation, ROT is halfway between a posterior and anterior position. If the baby was previously in a posterior position, ROT is a sign the baby is making a positive move toward an anterior position.

When a baby is in the left occiput transverse position (LOT) or right occiput transverse (ROT) position during labor, it may lead to more pain and a slower progression.

Tips to Reduce Discomfort

There are several labor positions a mother can try to alleviate pain and encourage the baby to continue rotating toward an anterior position, including:

  • Pelvic tilts
  • Standing and swaying

A doula , labor nurse, midwife , or doctor may have other suggestions for positions.

Right or Left Occiput Posterior

When facing forward, the baby is in the occiput posterior position. If the baby is facing forward and slightly to the left (looking toward the mother's right thigh) it is in the left occiput posterior (LOP) position. This presentation can lead to more back pain (sometimes referred to as " back labor ") and slow progression of labor.

In the right occiput posterior position (ROP), the baby is facing forward and slightly to the right (looking toward the mother's left thigh). This presentation may slow labor and cause more pain.

To help prevent or decrease pain during labor and encourage the baby to move into a better position for delivery, mothers can try a variety of positions, including:

  • Hands and knees
  • Pelvic rocking

Mothers may try other comfort measures, including:

  • Bathtub or shower (water)
  • Counter pressure
  • Movement (swaying, dancing, sitting on a birth ball )
  • Rice socks (heat packs)

How a Doctor Determines Baby's Position

Leopold's maneuvers are a series of hands-on examinations your doctor or midwife will use to help determine your baby's position. During the third trimester , the assessment will be done at most of your prenatal visits.   Knowing the baby's position before labor begins can help you prepare for labor and delivery.

Once labor begins, a nurse, doctor, or midwife will be able to get a more accurate sense of your baby's position by performing a vaginal exam. When your cervix is dilated enough, the practitioner will insert their fingers into the vagina and feel for the suture lines of the baby's skull as it moves down in the birth canal.   It's important to ensure the baby is head down and moving in the right direction.

Labor and delivery may be more complicated if the baby is not in a head-down position, such as in the case of a breech presentation.

How You Can Determine Baby's Position

While exams by health practitioners are an important part of your care, from the prenatal period through labor and delivery, often the best person to assess a baby's position in the pelvis is you. Mothers should pay close attention to how the baby moves and where different movements are felt.

A technique called belly mapping can help mothers ask questions of themselves to assess their baby's movement and get a sense of the position they are in as labor approaches.

For example, the position of your baby's legs can be determined by asking questions about the location and strength of the kicking you feel. The spots where you feel the strongest kicks are most likely where your baby's feet are.

Other landmarks you can feel for include a large, flat plane, which is most likely your baby's back. Sometimes you can feel the baby arching his or her back.

At the top or bottom of the flat plane, you may feel either a hard, round shape (most likely your baby's head) or a soft curve (most likely to be your baby's bottom).

  • Continuing Education Activity

Face and brow presentation is a malpresentation during labor when the presenting part is either the face or, in the case of brow presentation, it is the area between the orbital ridge and the anterior fontanelle. This activity reviews the evaluation and management of these two presentations and explains the role of the interprofessional team in managing delivery safely for both the mother and the baby.

  • Describe the mechanism of labor in the face and brow presentation.
  • Summarize potential maternal and fetal complications during the face and brow presentations.
  • Review different management approaches for the face and brow presentation.
  • Outline some interprofessional strategies that will improve patient outcomes in delivery cases with face and brow presentation issues.
  • Introduction

The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin. The most common presentation in term labor is the vertex, where the fetal neck is flexed to the chin, minimizing the head circumference.

Face presentation – an abnormal form of cephalic presentation where the presenting part is mentum. This typically occurs because of hyperextension of the neck and the occiput touching the fetal back. Incidence of face presentation is rare, accounting for approximately 1 in 600 of all presentations. [1] [2] [3]

In brow presentation, the neck is not extended as much as in face presentation, and the leading part is the area between the anterior fontanelle and the orbital ridges. Brow presentation is considered the rarest of all malpresentation with a prevalence of 1 in 500 to 1 in 4000 deliveries. [3]

Both face and brow presentations occur due to extension of the fetal neck instead of flexion; therefore, conditions that would lead to hyperextension or prevent flexion of the fetal neck can all contribute to face or brow presentation. These risk factors may be related to either the mother or the fetus. Maternal risk factors are preterm delivery, contracted maternal pelvis, platypelloid pelvis, multiparity, previous cesarean section, black race. Fetal risk factors include anencephaly, multiple loops of cord around the neck, masses of the neck, macrosomia, polyhydramnios. [2] [4] [5]

These malpresentations are usually diagnosed during the second stage of labor when performing a digital examination. It is possible to palpate orbital ridges, nose, malar eminences, mentum, mouth, gums, and chin in face presentation. Based on the position of the chin, face presentation can be further divided into mentum anterior, posterior, or transverse. In brow presentation, anterior fontanelle and face can be palpated except for the mouth and the chin. Brow presentation can then be further described based on the position of the anterior fontanelle as frontal anterior, posterior, or transverse.

Diagnosing the exact presentation can be challenging, and face presentation may be misdiagnosed as frank breech. To avoid any confusion, a bedside ultrasound scan can be performed. [6]  The ultrasound imaging can show a reduced angle between the occiput and the spine or, the chin is separated from the chest. However, ultrasound does not provide much predicting value in the outcome of the labor. [7]

  • Anatomy and Physiology

Before discussing the mechanism of labor in the face or brow presentation, it is crucial to highlight some anatomical landmarks and their measurements. 

Planes and Diameters of the Pelvis

The three most important planes in the female pelvis are the pelvic inlet, mid pelvis, and pelvic outlet. 

Four diameters can describe the pelvic inlet: anteroposterior, transverse, and two obliques. Furthermore, based on the different landmarks on the pelvic inlet, there are three different anteroposterior diameters, named conjugates: true conjugate, obstetrical conjugate, and diagonal conjugate. Only the latter can be measured directly during the obstetric examination. The shortest of these three diameters is obstetrical conjugate, which measures approximately 10.5 cm and is a distance between the sacral promontory and 1 cm below the upper border of the symphysis pubis. This measurement is clinically significant as the fetal head must pass through this diameter during the engagement phase. The transverse diameter measures about 13.5cm and is the widest distance between the innominate line on both sides. 

The shortest distance in the mid pelvis is the interspinous diameter and usually is only about 10 cm. 

Fetal Skull Diameters

There are six distinguished longitudinal fetal skull diameters:

  • Suboccipito-bregmatic: from the center of anterior fontanelle (bregma) to the occipital protuberance, measuring 9.5 cm. This is the presenting diameter in vertex presentation. 
  • Suboccipito-frontal: from the anterior part of bregma to the occipital protuberance, measuring 10 cm 
  • Occipito-frontal: from the root of the nose to the most prominent part of the occiput, measuring 11.5cm
  • Submento-bregmatic: from the center of the bregma to the angle of the mandible, measuring 9.5 cm. This is the presenting diameter in face presentation where the neck is hyperextended. 
  • Submento-vertical: from the midpoint between fontanelles and the angle of the mandible, measuring 11.5cm 
  • Occipito-mental: from the midpoint between fontanelles and the tip of the chin, measuring 13.5 cm. It is the presenting diameter in brow presentation. 

Cardinal Movements of Normal Labor

  • Neck flexion
  • Internal rotation
  • Extension (delivers head)
  • External rotation (Restitution)
  • Expulsion (delivery of anterior and posterior shoulders)

Some of the key movements are not possible in the face or brow presentations.  

Based on the information provided above, it is obvious that labor will be arrested in brow presentation unless it spontaneously changes to face or vertex, as the occipito-mental diameter of the fetal head is significantly wider than the smallest diameter of the female pelvis. Face presentation can, however, be delivered vaginally, and further mechanisms of face delivery will be explained in later sections.

  • Indications

As mentioned previously, spontaneous vaginal delivery can be successful in face presentation. However, the main indication for vaginal delivery in such circumstances would be a maternal choice. It is crucial to have a thorough conversation with a mother, explaining the risks and benefits of vaginal delivery with face presentation and a cesarean section. Informed consent and creating a rapport with the mother is an essential aspect of safe and successful labor.

  • Contraindications

Vaginal delivery of face presentation is contraindicated if the mentum is lying posteriorly or is in a transverse position. In such a scenario, the fetal brow is pressing against the maternal symphysis pubis, and the short fetal neck, which is already maximally extended, cannot span the surface of the maternal sacrum. In this position, the diameter of the head is larger than the maternal pelvis, and it cannot descend through the birth canal. Therefore the cesarean section is recommended as the safest mode of delivery for mentum posterior face presentations. 

Attempts to manually convert face presentation to vertex, manual or forceps rotation of the persistent posterior chin to anterior are contraindicated as they can be dangerous.

Persistent brow presentation itself is a contraindication for vaginal delivery unless the fetus is significantly small or the maternal pelvis is large.

Continuous electronic fetal heart rate monitoring is recommended for face and brow presentations, as heart rate abnormalities are common in these scenarios. One study found that only 14% of the cases with face presentation had no abnormal traces on the cardiotocograph. [8] It is advised to use external transducer devices to prevent damage to the eyes. When internal monitoring is inevitable, it is suggested to place monitoring devices on bony parts carefully. 

People who are usually involved in the delivery of face/ brow presentation are:

  • Experienced midwife, preferably looking after laboring woman 1:1
  • Senior obstetrician 
  • Neonatal team - in case of need for resuscitation 
  • Anesthetic team - to provide necessary pain control (e.g., epidural)
  • Theatre team  - in case of failure to progress and an emergency cesarean section will be required.
  • Preparation

No specific preparation is required for face or brow presentation. However, it is essential to discuss the labor options with the mother and birthing partner and inform members of the neonatal, anesthetic, and theatre co-ordinating teams.

  • Technique or Treatment

Mechanism of Labor in Face Presentation

During contractions, the pressure exerted by the fundus of the uterus on the fetus and pressure of amniotic fluid initiate descent. During this descent, the fetal neck extends instead of flexing. The internal rotation determines the outcome of delivery, if the fetal chin rotates posteriorly, vaginal delivery would not be possible, and cesarean section is permitted. The approach towards mentum-posterior delivery should be individualized, as the cases are rare. Expectant management is acceptable in multiparous women with small fetuses, as a spontaneous mentum-anterior rotation can occur. However, there should be a low threshold for cesarean section in primigravida women or women with large fetuses.

When the fetal chin is rotated towards maternal symphysis pubis as described as mentum-anterior; in these cases further descend through the vaginal canal continues with approximately 73% cases deliver spontaneously. [9] Fetal mentum presses on the maternal symphysis pubis, and the head is delivered by flexion. The occiput is pointing towards the maternal back, and external rotation happens. Shoulders are delivered in the same manner as in vertex delivery.

Mechanism of Labor in Brow Presentation

As this presentation is considered unstable, it is usually converted into a face or an occiput presentation. Due to the cephalic diameter being wider than the maternal pelvis, the fetal head cannot engage; thus, brow delivery cannot take place. Unless the fetus is small or the pelvis is very wide, the prognosis for vaginal delivery is poor. With persistent brow presentation, a cesarean section is required for safe delivery.

  • Complications

As the cesarean section is becoming a more accessible mode of delivery in malpresentations, the incidence of maternal and fetal morbidity and mortality during face presentation has dropped significantly. [10]

However, there are still some complications associated with the nature of labor in face presentation. Due to the fetal head position, it is more challenging for the head to engage in the birth canal and descend, resulting in prolonged labor.

Prolonged labor itself can provoke foetal distress and arrhythmias. If the labor arrests or signs of fetal distress appear on CTG, the recommended next step in management is an emergency cesarean section, which in itself carries a myriad of operative and post-operative complications.

Finally, due to the nature of the fetal position and prolonged duration of labor in face presentation, neonates develop significant edema of the skull and face. Swelling of the fetal airway may also be present, resulting in respiratory distress after birth and possible intubation.

  • Clinical Significance

During vertex presentation, the fetal head flexes, bringing the chin to the chest, forming the smallest possible fetal head diameter, measuring approximately 9.5cm. With face and brow presentation, the neck hyperextends, resulting in greater cephalic diameters. As a result, the fetal head will engage later, and labor will progress more slowly. Failure to progress in labor is also more common in both presentations compared to vertex presentation.

Furthermore, when the fetal chin is in a posterior position, this prevents further flexion of the fetal neck, as browns are pressing on the symphysis pubis. As a result, descend through the birth canal is impossible. Such presentation is considered undeliverable vaginally and requires an emergency cesarean section.

Manual attempts to change face presentation to vertex, manual or forceps rotation to mentum anterior are considered dangerous and are discouraged.

  • Enhancing Healthcare Team Outcomes

A multidisciplinary team of healthcare experts supports the woman and her child during labor and the perinatal period. For a face or brow presentation to be appropriately diagnosed, an experienced midwife and obstetrician must be involved in the vaginal examination and labor monitoring. As fetal anomalies, such as anencephaly or goiter, can contribute to face presentation, sonographers experienced in antenatal scanning should also be involved in the care. It is advised to inform the anesthetic and neonatal teams in advance of the possible need for emergency cesarean section and resuscitation of the neonate. [11] [12]

Breech Births

In the last weeks of pregnancy, a baby usually moves so his or her head is positioned to come out of the vagina first during birth. This is called a vertex presentation. A breech presentation occurs when the baby’s buttocks, feet, or both are positioned to come out first during birth. This happens in 3–4% of full-term births.

What are the different types of breech birth presentations?

  • Complete breech: Here, the buttocks are pointing downward with the legs folded at the knees and feet near the buttocks.
  • Frank breech: In this position, the baby’s buttocks are aimed at the birth canal with its legs sticking straight up in front of his or her body and the feet near the head.
  • Footling breech: In this position, one or both of the baby’s feet point downward and will deliver before the rest of the body.

What causes a breech presentation?

The causes of breech presentations are not fully understood. However, the data show that breech birth is more common when:

  • You have been pregnant before
  • In pregnancies of multiples
  • When there is a history of premature delivery
  • When the uterus has too much or too little amniotic fluid
  • When there is an abnormally shaped uterus or a uterus with abnormal growths, such as fibroids
  • The placenta covers all or part of the opening of the uterus placenta previa

How is a breech presentation diagnosed?

A few weeks prior to the due date, the health care provider will place her hands on the mother’s lower abdomen to locate the baby’s head, back, and buttocks. If it appears that the baby might be in a breech position, they can use ultrasound or pelvic exam to confirm the position. Special x-rays can also be used to determine the baby’s position and the size of the pelvis to determine if a vaginal delivery of a breech baby can be safely attempted.

Can a breech presentation mean something is wrong?

Even though most breech babies are born healthy, there is a slightly elevated risk for certain problems. Birth defects are slightly more common in breech babies and the defect might be the reason that the baby failed to move into the right position prior to delivery.

Can a breech presentation be changed?

It is preferable to try to turn a breech baby between the 32nd and 37th weeks of pregnancy . The methods of turning a baby will vary and the success rate for each method can also vary. It is best to discuss the options with the health care provider to see which method she recommends.

Medical Techniques

External Cephalic Version (EVC)  is a non-surgical technique to move the baby in the uterus. In this procedure, a medication is given to help relax the uterus. There might also be the use of an ultrasound to determine the position of the baby, the location of the placenta and the amount of amniotic fluid in the uterus.

Gentle pushing on the lower abdomen can turn the baby into the head-down position. Throughout the external version the baby’s heartbeat will be closely monitored so that if a problem develops, the health care provider will immediately stop the procedure. ECV usually is done near a delivery room so if a problem occurs, a cesarean delivery can be performed quickly. The external version has a high success rate and can be considered if you have had a previous cesarean delivery.

ECV will not be tried if:

  • You are carrying more than one fetus
  • There are concerns about the health of the fetus
  • You have certain abnormalities of the reproductive system
  • The placenta is in the wrong place
  • The placenta has come away from the wall of the uterus ( placental abruption )

Complications of EVC include:

  • Prelabor rupture of membranes
  • Changes in the fetus’s heart rate
  • Placental abruption
  • Preterm labor

Vaginal delivery versus cesarean for breech birth?

Most health care providers do not believe in attempting a vaginal delivery for a breech position. However, some will delay making a final decision until the woman is in labor. The following conditions are considered necessary in order to attempt a vaginal birth:

  • The baby is full-term and in the frank breech presentation
  • The baby does not show signs of distress while its heart rate is closely monitored.
  • The process of labor is smooth and steady with the cervix widening as the baby descends.
  • The health care provider estimates that the baby is not too big or the mother’s pelvis too narrow for the baby to pass safely through the birth canal.
  • Anesthesia is available and a cesarean delivery possible on short notice

What are the risks and complications of a vaginal delivery?

In a breech birth, the baby’s head is the last part of its body to emerge making it more difficult to ease it through the birth canal. Sometimes forceps are used to guide the baby’s head out of the birth canal. Another potential problem is cord prolapse . In this situation the umbilical cord is squeezed as the baby moves toward the birth canal, thus slowing the baby’s supply of oxygen and blood. In a vaginal breech delivery, electronic fetal monitoring will be used to monitor the baby’s heartbeat throughout the course of labor. Cesarean delivery may be an option if signs develop that the baby may be in distress.

When is a cesarean delivery used with a breech presentation?

Most health care providers recommend a cesarean delivery for all babies in a breech position, especially babies that are premature. Since premature babies are small and more fragile, and because the head of a premature baby is relatively larger in proportion to its body, the baby is unlikely to stretch the cervix as much as a full-term baby. This means that there might be less room for the head to emerge.

Fetal Presentation, Position, and Lie (Including Breech Presentation)

  • Key Points |

Abnormal fetal lie or presentation may occur due to fetal size, fetal anomalies, uterine structural abnormalities, multiple gestation, or other factors. Diagnosis is by examination or ultrasonography. Management is with physical maneuvers to reposition the fetus, operative vaginal delivery , or cesarean delivery .

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for transverse presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

what is presentation in pregnancy

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

what is presentation in pregnancy

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor. Operative vaginal delivery or cesarean delivery is often required.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

Spinning Babies

Why would posterior position matter in labor?  The head is angled so that it measures larger. The top of the head molds less than the crown.

Baby’s spine is extended, not curled, so the crown of the head is not leading the way. Baby can’t help as much during the birth process to the same degree as the curled up baby.

Some posteriors are easy, while others are long and painful, and there are several ways to tell how your labor will be beforehand. After this, you may want to visit What to do when….in Labor .

Anterior and Posterior Positionss

Belly Mapping ® Method tips:  The Right side of the abdomen is almost always firmer, but the direct OP baby may not favor one side or the other. Baby’s limbs are felt in front, on both sides of the center line. A knee may slide past under the navel.

The OP position (occiput posterior fetal position) is when the back of the baby’s head is against the mother’s back. Here are drawings of an anterior and posterior presentation.

ROP

Look at the above drawing. The posterior baby’s back is often extended straight or arched along the mother’s spine. Having the baby’s back extended often pushes the baby’s chin up.

Attention: Having the chin up is what makes the posterior baby’s head seem larger than the same baby when it’s in the anterior position.

Because the top of the head enters (or tries to enter) the pelvis first, baby seems much bigger by the mother’s measurements. A posterior head circumference measures larger than the anterior head circumference.

A large baby is not the same issue, however. The challenge with a posterior labor is that the top of the head, not the crown of the head leads the way.

A baby with their spine straight has less ability to wiggle and so the person giving birth has to do the work of two. This can be long and challenging or fast and furious. Also, there are a few posterior labors that are not perceived different than a labor with a baby curled on the left.

Why? Anatomy makes the difference. Learn to work with birth anatomy to reduce the challenge of posterior labor by preparing with our Three Balances SM and more.

There are four posterior positions

The direct OP is the classic posterior position with the baby facing straight forward.   Right Occiput Transverse   (ROT) is a common starting position in which the baby has a bit more likelihood of rotating to the posterior during labor than to the anterior.   Right Occiput Posterior   usually involves a straight back with a lifted chin (in the first-time mother). Left Occiput Posterior places the baby’s back opposite the maternal liver and may let the baby flex (curl) his or her back and therefore tuck the chin for a better birth. These are generalities, of course. See a bit more about posterior positions in   Belly Mapping ® on this website. Want to map your baby’s position? Learn how with the   Belly Mapping ® Workbook .

Pregnancy may or may not show symptoms.   Just because a woman’s back doesn’t hurt in pregnancy doesn’t mean the baby is not posterior. Just because a woman is quite comfortable in pregnancy doesn’t mean the baby is not posterior. A woman can’t always feel the baby’s limbs moving in front to tell if the baby is facing the front.

Four starting positions often lead to (or remain as) direct   OP   in active labor.   Right Occiput Transverse   (ROT),   Right Occiput Posterior   (ROP), and Left Occiput Posterior (LOP) join direct OP in adding labor time. The LOP baby has less distance to travel to get into an LOT position.

As labor begins, the high-riding, unengaged Right Occiput Transverse baby slowly rotates to   ROA , working past the sacral promontory at the base of the spine before swinging around to LOT to engage in the pelvis. Most babies go on to OA at the pelvic floor or further down on the perineal floor.

If a baby engages as a ROT, they may go to OP or ROA by the time they descend to the midpelvis. The OP baby may stay OP. For some, once the head is lower than the bones and the head is visible at the perineum, the baby rotates and helpers may see the baby’s head turn then! These babies finish in the ROA or OA positions.

Feeling both hands in front, in two separate but low places on the abdomen, indicates a posterior fetal position. This baby is Left Occiput Posterior.

Studies estimate 15-30% of babies are OP in labor. Jean Sutton in   Optimal Fetal Positioning   states that 50% of babies trend toward posterior in early labor upon admission to the hospital. Strong latent labor swings about a third of these to LOT before dilation begins (in “pre-labor” or “false labor”).

Recent research shows about 50% of babies are in a posterior position when active labor begins, but of these, 3/4 of them rotate to anterior (or facing a hip in an occiput transverse, head down position.

Jean Sutton’s observations, reported in her 1996 book, indicates that some babies starting in a posterior position will rotate before arriving to the hospital. Ellice Lieberman observed most posteriors will rotate out of posterior into either anterior or to facing a hip throughout labor. Only 5-8% of all babies emerge directly OP (13% with an epidural in Lieberman’s study). At least 12% of all   cesareans   are for OP babies that are stuck due to the larger diameter of the OP head in comparison to the OA head. It’s more common for ROT, ROP, and OP babies to rotate during labor and to emerge facing back (OA). Some babies become stuck halfway through a long-arc rotation and some will need a cesarean anyway.

Why not ROA? ROA babies may have their chins up and this deflexed position may lengthen the course of labor. Less than 4% of starting positions are ROA, according to a Birmingham study. This might not be ideal for first babies, but is not a posterior position either.

Baby’s posterior position may matter in labor

With a posterior presentation, labor may or may not be significantly affected. There is a spectrum of possibilities with a posterior baby. Some women will not know they had a posterior baby because no one mentions it. Either the providers didn’t know, or didn’t notice. If labor moved along, they may not have looked at fetal position clues since there was no reason to figure out why labor wasn’t progressing. If a woman didn’t have back labor (more pain in her back than in her abdomen), the provider may not have been “clued into” baby’s position.

Some posterior babies are born in less than 8 hours and position did not slow down labor. Some posterior babies are born in less than 24 hours and position did not slow down labor enough to be out of the norm. Some posterior babies are born in less than 36-48 hours without the need for interventions.

Some posterior labors are manageable when women are mobile, supported, and eat and drink freely, as needed. Some posterior labor needs extra support that a well-trained and experienced doula may provide, but that typically a mate or loved one would not have the skills or stamina to keep up with. Some posterior labors progress only with the help of a highly-trained pregnancy bodyworker or deep spiritual, or otherwise a non-conventional model of care. Or, they seem only able to finish with medical intervention.

Some posterior labors are served by an epidural, meaning the pelvic floor relaxes enough for the baby to rotate and come out. Some epidurals, on the other hand, make it so that a woman can not finish the birth vaginally.

NOTE:   Parents should know — some birth researchers, like Pediatrician John Kennell, are seriously asking whether a mother’s epidural turns off her body’s release of pain-relieving hormones which a baby relies on during childbirth. Some babies can’t turn and can’t be born vaginally and must be born by   cesarean. This is a spectrum of possibilities. I’ve seen every one of the above possibilities several times and can add the wonderful experience of seeing a woman laughing pleasurably and squatting while her posterior baby slid out on to her bedroom floor.

Possible posterior effects, some women will have one or two and some will have many of these:

overlap.250

The forehead that overlaps the pubic bone after labor starts must turn and drop into the pelvis to allow the birth to happen naturally. A cesarean finish of the labor is possible. Look at Abdominal Lift and Tuck in Techniques to guide you to solutions for easier engagement and progress.

  • Longer pregnancy (some research shows this and some doesn’t)
  • The amniotic sac breaking (water breaks, membranes open, rupture of membranes) before labor (1 in 5 OP labors)
  • Not starting in time before induction   is scheduled
  • Labor is longer and stronger and less rhythmic than expected
  • Start and stop   labor pattern
  • The baby may not engage, even during the pushing stage
  • Longer early labor
  • Longer active labor
  • Back labor (in some cases)
  • Pitocin may be used when labor stalls (but a snoring good rest followed by oatmeal may restore a contraction pattern, too)
  • Longer pushing stage
  • Maybe a woman has all three phases of labor lengthened by the OP labor or one or two of the three phases listed
  • Sometimes the baby’s head gets stuck turned halfway to anterior – in the transverse diameter. This may be called a transverse arrest (not a   transverse lie ).
  • More likely to tear
  • More likely to need a vacuum (ventouse) or forceps
  • More likely to need a   cesarean

These effects are in comparison to a baby in the   left occiput anterior   or   left occiput transverse   fetal position at the start of labor.

Who might have a hard time with a posterior baby?

what is presentation in pregnancy

This family just had a fast posterior birth of their second child! Ease in labor includes other factors beyond baby position.

  • A first-time mom
  • A first-time mom whose   baby hasn’t dropped into the pelvis by 38 weeks gestation   (two weeks before the due date)
  • A woman with an   android pelvis   (“runs like a boy,” often long and lanky, low pubis with narrow pubic arch and/or sitz bones close together, closer than or equal to the width of a fist)
  • A woman whose baby, in the third trimester, doesn’t seem to change position at all, over the weeks. He or she kicks in the womb and stretches, but whose trunk is stationary for weeks. This mother’s broad ligament may be so tight that she may be uncomfortable when baby moves.
  • A woman who has an epidural early in labor (data supports this), before the baby has a chance to rotate and come down.
  • A woman who labors lying in bed
  • Low-thyroid, low-energy woman who has gone overdue (this is my observation)
  • A woman who lacks support by a calm and assured woman who is calming and reassuring to the birthing mother (a doula)
  • A woman put on the clock
  • A woman who refuses all help when the labor exceeds her ability to physically sustain her self (spilling ketones, dehydration, unable to eat or rest in a labor over X amount of hours which might be 24 for some or 48 for others)
  • A woman whose birth team can’t match an appropriate technique to the needs of the baby for flexion, rotation, and/or descent from the level of the pelvis where the baby is currently at when stuck

Who is likely to have an easy time with a posterior baby?

  • A second-time mom who’s given birth readily before (and pushing went well)
  • A posterior baby with a tucked chin on his or her mama’s left side with   a round pelvic brim
  • An average-sized or smaller baby
  • Someone whose posterior baby changes from right to left after doing inversions and other   balancing work , though the baby is still posterior
  • A woman with a baby in the Left Occiput Posterior, especially if the baby’s chin is tucked or flexed
  • A woman who gets bodywork, myofascial release, etc.
  • A woman whose posterior baby engages, and does not have an   android (triangular) pelvis or a small outlet
  • And of all of these, what is necessary is a pelvis big enough to accommodate the baby’s extra head size
  • A woman who uses active birthing techniques — vertical positions, moves spontaneously and instinctively or with specific techniques from Spinning Babies ® , and other good advice
  • A woman in a balanced nervous state, not so alert and “pumped up,” on guard, etc.

Any woman may also have an easier time than public opinion might indicate, too, just because she isn’t on this list. Equally, just because she is on the “hard” list doesn’t mean she will have a hard time for sure. These are general observations. They are neither condemnations nor promises. Overall, some posterior babies will need help getting born, while some posterior babies are born easily (easy being a relative term).

Let’s not be ideological about posterior labors.

While most posterior babies do eventually rotate, that can still mean there is quite a long wait – and a lot of physical labor during that wait. Sometimes it means the doula, midwife, nurse, or doctor is asking the mother to do a variety of position changes, techniques, and even medical interventions to help finish the labor. Patience works for many, but for some a   cesarean   is really the only way to be born. Read   What To Do When…in Labor .

What causes a baby to be posterior?

There is a rising incidence of posterior babies at the time of birth. We know now that epidural anesthesia increases the rate of posterior position at the time of birth from about 4% (for women who don’t choose an epidural in a university birth setting) up to about 13% (Lieberman, 2005). Low thyroid function is associated with fetal malposition such as posterior or breech. (See   Research & References .)

Most babies who are posterior early in labor will rotate to anterior once labor gets going. Some babies rotate late in labor, even just before emerging. Studies such as Lieberman’s show that at any given phase of labor, another 20% of posterior babies will rotate so that only a small number are still posterior as the head emerges.

My observations are that the majority of babies are posterior before labor. The high numbers of posterior babies at the end of pregnancy and in the early phase of labor is a change from what was seen in studies over ten years old. Perhaps this is from our cultural habits of sitting at desks, sitting in bucket seats (cars), and leaning back on the couch (slouching). Soft tissues such as the psoas muscle pair or the broad ligament also seem to be tight more often from these postures, from athletics (quick stops, jolts, and falls), from accidents, and from emotional or sexual assault.

Being a nurse or bodyworker who turns to care for people in a bed or on a table will also twist the lower uterine segment (along with some of the previously mentioned causes). This makes the baby have to compensate in a womb that is no longer symmetrical. Less often, the growing baby settles face-forward over a smaller pelvis, or a triangular-shaped pelvis (android). At the end of pregnancy, the baby’s forehead has settled onto a narrower than usual pubic bone, and if tight round ligaments hold the forehead there, the baby may have a tough time rotating. These are the moms and babies that I’m most concerned with in my work at Spinning Babies®. A baby that was   breech   beyond week 30 – 34 of pregnancy will flip head down in the posterior position. A woman with a history of breech or posterior babies is more likely to have a breech or posterior baby in the next pregnancy. However, she may not have an as long labor.

The best way to tell if your baby is OP or not, usually, is if you feel little wiggles in the abdomen right above your pubic bone. These are the fingers. They’d feel like little fingers wiggling, not like a big thunk or grinding from the head, though you might feel that, too. The little fingers will be playing by the mouth. This is the easiest indication of OP. The wiggles will be centered in the middle of your lower abdomen, close to the pubic bone. If you feel wiggles far to the right, near your hip, and kicks above on the right, but not near the center and none on the left, then those signal an   OA   or   LOT   baby (who will rotate to the OA easily in an active birth). After this, you might go to   What to do when…in Labor.

What Is Breech?

When a fetus is delivered buttocks or feet first

  • Types of Presentation

Risk Factors

Complications.

Breech concerns the position of the fetus before labor . Typically, the fetus comes out headfirst, but in a breech delivery, the buttocks or feet come out first. This type of delivery is risky for both the pregnant person and the fetus.

This article discusses the different types of breech presentations, risk factors that might make a breech presentation more likely, treatment options, and complications associated with a breech delivery.

Verywell / Jessica Olah

Types of Breech Presentation

During the last few weeks of pregnancy, a fetus usually rotates so that the head is positioned downward to come out of the vagina first. This is called the vertex position.

In a breech presentation, the fetus does not turn to lie in the correct position. Instead, the fetus’s buttocks or feet are positioned to come out of the vagina first.

At 28 weeks of gestation, approximately 20% of fetuses are in a breech position. However, the majority of these rotate to the proper vertex position. At full term, around 3%–4% of births are breech.

The different types of breech presentations include:

  • Complete : The fetus’s knees are bent, and the buttocks are presenting first.
  • Frank : The fetus’s legs are stretched upward toward the head, and the buttocks are presenting first.
  • Footling : The fetus’s foot is showing first.

Signs of Breech

There are no specific symptoms associated with a breech presentation.

Diagnosing breech before the last few weeks of pregnancy is not helpful, since the fetus is likely to turn to the proper vertex position before 35 weeks gestation.

A healthcare provider may be able to tell which direction the fetus is facing by touching a pregnant person’s abdomen. However, an ultrasound examination is the best way to determine how the fetus is lying in the uterus.

Most breech presentations are not related to any specific risk factor. However, certain circumstances can increase the risk for breech presentation.

These can include:

  • Previous pregnancies
  • Multiple fetuses in the uterus
  • An abnormally shaped uterus
  • Uterine fibroids , which are noncancerous growths of the uterus that usually appear during the childbearing years
  • Placenta previa, a condition in which the placenta covers the opening to the uterus
  • Preterm labor or prematurity of the fetus
  • Too much or too little amniotic fluid (the liquid that surrounds the fetus during pregnancy)
  • Fetal congenital abnormalities

Most fetuses that are breech are born by cesarean delivery (cesarean section or C-section), a surgical procedure in which the baby is born through an incision in the pregnant person’s abdomen.

In rare instances, a healthcare provider may plan a vaginal birth of a breech fetus. However, there are more risks associated with this type of delivery than there are with cesarean delivery. 

Before cesarean delivery, a healthcare provider might utilize the external cephalic version (ECV) procedure to turn the fetus so that the head is down and in the vertex position. This procedure involves pushing on the pregnant person’s belly to turn the fetus while viewing the maneuvers on an ultrasound. This can be an uncomfortable procedure, and it is usually done around 37 weeks gestation.

ECV reduces the risks associated with having a cesarean delivery. It is successful approximately 40%–60% of the time. The procedure cannot be done once a pregnant person is in active labor.

Complications related to ECV are low and include the placenta tearing away from the uterine lining, changes in the fetus’s heart rate, and preterm labor.

ECV is usually not recommended if the:

  • Pregnant person is carrying more than one fetus
  • Placenta is in the wrong place
  • Healthcare provider has concerns about the health of the fetus
  • Pregnant person has specific abnormalities of the reproductive system

Recommendations for Previous C-Sections

The American College of Obstetricians and Gynecologists (ACOG) says that ECV can be considered if a person has had a previous cesarean delivery.

During a breech delivery, the umbilical cord might come out first and be pinched by the exiting fetus. This is called cord prolapse and puts the fetus at risk for decreased oxygen and blood flow. There’s also a risk that the fetus’s head or shoulders will get stuck inside the mother’s pelvis, leading to suffocation.

Complications associated with cesarean delivery include infection, bleeding, injury to other internal organs, and problems with future pregnancies.

A healthcare provider needs to weigh the risks and benefits of ECV, delivering a breech fetus vaginally, and cesarean delivery.

In a breech delivery, the fetus comes out buttocks or feet first rather than headfirst (vertex), the preferred and usual method. This type of delivery can be more dangerous than a vertex delivery and lead to complications. If your baby is in breech, your healthcare provider will likely recommend a C-section.

A Word From Verywell

Knowing that your baby is in the wrong position and that you may be facing a breech delivery can be extremely stressful. However, most fetuses turn to have their head down before a person goes into labor. It is not a cause for concern if your fetus is breech before 36 weeks. It is common for the fetus to move around in many different positions before that time.

At the end of your pregnancy, if your fetus is in a breech position, your healthcare provider can perform maneuvers to turn the fetus around. If these maneuvers are unsuccessful or not appropriate for your situation, cesarean delivery is most often recommended. Discussing all of these options in advance can help you feel prepared should you be faced with a breech delivery.

Malpresentation

8-minute read

If you feel your waters break and you have been told that your baby is not in a head-first position, seek medical help immediately .

  • Malpresentation is when your baby is not facing head-first down the birth canal as birth approaches.
  • The most common type of malpresentation is breech — when your baby’s bottom or feet are facing downwards.
  • A procedure called external cephalic version can sometimes turn a breech baby into a head-first position at 36 weeks.
  • Most babies with malpresentation are born by caesarean, but you may be able to have a vaginal birth if your baby is breech.
  • There is a serious risk of cord prolapse if your waters break and your baby is not head-first.

What are presentation and malpresentation?

‘Presentation’ describes how your baby is facing down the birth canal. The ‘presenting part’ is the part of your baby’s body that is against the cervix .

The ideal presentation is head-first, with the crown (top) of the baby’s head against the cervix, with the chin tucked into the baby’s chest. This is called ‘vertex presentation’.

If your baby is in any other position, it’s called ‘malpresentation’. Malpresentation can mean your baby’s face, brow, buttocks, foot, back, shoulder, arms or legs or the umbilical cord are against the cervix.

It’s safest for your baby’s head to come out first. If any other body part goes down the birth canal first, the risks to you and your baby may be higher. Malpresentation increases the chance that you will have a more complex vaginal birth or a caesarean.

If my baby is not head-first, what position could they be in?

Malpresentation is caused by your baby’s position (‘lie’). There are different types of malpresentation.

Breech presentation

This is when your baby is lying with their bottom or feet facing down. Sometimes one foot may enter the birth canal first (called a ‘footling presentation’).

Breech presentation is the most common type of malpresentation.

Face presentation

This is when your baby is head-first but stretching their neck, with their face against the cervix.

Transverse lie

This is when your baby is lying sideways. Their back, shoulders, arms or legs may be the first to enter the birth canal.

Oblique lie

This is when your baby is lying diagonally. No particular part of their body is against the cervix.

Unstable lie

This is when your baby continually changes their position after 36 weeks of pregnancy.

Cord presentation

This is when the umbilical cord is against the cervix, between your baby and the birth canal. It can happen in any situation where your baby’s presenting part is not sitting snugly in your pelvis. It can become an emergency if it leads to cord prolapse (when the cord is born before your baby, potentially reducing placental blood flow to your baby).

What is malposition?

If your baby is lying head-first, the best position for labour is when their face is towards your back.

If your baby is facing the front of your body (posterior position) or facing your side (transverse position) this is called malposition. Transverse position is not the same as transverse lie. A transverse position means your labour may take a bit longer and you might feel more pain in your back. Often your baby will move into a better position before or during labour.

Why might my baby be in the wrong position?

Malpresentation may be caused by:

  • a low-lying placenta
  • too much or too little amniotic fluid
  • many previous pregnancies, making the muscles of the uterus less stable
  • carrying twins or more

Often no cause is found.

Is it likely that my baby will be in the wrong position?

Many babies are in a breech position during pregnancy. They usually turn head-first as pregnancy progresses, and more than 9 in 10 babies in Australia have a vertex presentation (ideal presentation, head-first) at birth.

You are more likely to have a malpresentation if:

  • this is your first baby
  • you are over 40 years old
  • you've had a previous breech baby
  • you go into labour prematurely

How is malpresentation diagnosed?

Malpresentation is normally diagnosed when your doctor or midwife examines you, from 36 weeks of pregnancy. If it’s not clear, it can be confirmed with an ultrasound.

Can my baby’s position be changed?

If you are 36 weeks pregnant , it may be possible to gently turn your baby into a head-first position. This is done by an obstetrician using a technique called external cephalic version (ECV).

Some people try different postures or acupuncture to correct malpresentation, but there isn’t reliable evidence that either of these work.

Will I need a caesarean if my baby has a malpresentation?

Most babies with a malpresentation close to birth are born by caesarean . You may be able to have a vaginal birth with a breech baby, but you will need to go to a hospital that can offer you and your baby specialised care.

If your baby is breech, an elective (planned) caesarean is safer for your baby than a vaginal birth in the short term. However, in the longer term their health will be similar, on average, regardless of how they were born.

A vaginal birth is safer for you than an elective caesarean. However, about 4 in 10 people planning a vaginal breech birth end up needing an emergency caesarean . If this happens to you, the risk of complications will be higher.

Your doctor can talk to you about your options. Whether it’s safe for you to try a vaginal birth will depend on many factors. These include how big your baby is, the position of your baby, the structure of your pelvis and whether you’ve had a caesarean in the past.

What are the risks if I have my baby when it’s not head-first?

If your waters break when your baby is not head-first, there is a risk of cord prolapse. This is an emergency.

Vaginal breech birth

Risks to your baby can include:

  • Erb’s palsy
  • fractures, dislocations or other injuries
  • bleeding in your baby’s brain
  • low Apgar scores
  • their head getting stuck – this is an emergency

Risks to you include:

  • blood loss or blood clots
  • infection in the wound
  • problems with the anaesthetic
  • damage to other organs nearby, such as your bladder
  • a higher chance of problems in future pregnancies
  • a longer recovery time than after a vaginal birth

Risks to your baby include:

  • trouble with breathing — this is temporary
  • getting a small cut during the surgery

Will I have a malpresentation in my future pregnancies?

If you had a malpresentation in one pregnancy, you have a higher chance of it happening again, but it won’t necessarily happen in future pregnancies. If you’re worried, it may help to talk to your doctor or midwife so they can explain what happened.

Malpresentation and Malposition of the Fetus

A malpresentation or malposition of the fetus is when the fetus is in any abnormal position, other than vertex (head down) with the occiput anterior or posterior.

The following are considered malpresentations or malpositions:

Unstable lie

  • Transverse presentation
  • Oblique presentation

Face presentation

Brow presentation

Shoulder presentation

High head at term

  • Prolapsed arm

The cause of a malpresentation can often not be clearly identified but it can be associated with the following:

  • Preterm pregnancy
  • Uterine anomalies
  • Pelvic tumors eg f ibroids
  • Placenta previa
  • Grandmultiparty
  • Contracted maternal pelvis
  • Multiple gestation
  • Too much amniotic fluyid (polyhydramnios)
  • Short umbilical cord
  • Fetal anomalies (e.g. anencephaly, hydro-cephalus)
  • Abnormal fetal motor ability

There is an increased risk of neonatal and maternal complications associated with a malpresentation including neonatal and maternal trauma. If delivery is indicated, doing a cesarean delivery can significantly decrease the risk of complications.

Transverse lie

Oblique lie

In most cases of a normal vertex (head down) presentation, the baby's head is flexed with the chin close to the baby's chest. In these cases, the presenting part is the occiput, the posterior part of the baby's head. If the baby's head is more but not completekly extended then the baby's brow presents towards the vagina. A brow presentation is rare, maybe happening in about 1 in 2,000 births, more likely in pwomen with their second or subsequent births. A baby with a brow presentation can only deliver vaginally if the head flexes or extends.

Key facts about the abortion debate in America

A woman receives medication to terminate her pregnancy at a reproductive health clinic in Albuquerque, New Mexico, on June 23, 2022, the day before the Supreme Court overturned Roe v. Wade, which had guaranteed a constitutional right to an abortion for nearly 50 years.

The U.S. Supreme Court’s June 2022 ruling to overturn Roe v. Wade – the decision that had guaranteed a constitutional right to an abortion for nearly 50 years – has shifted the legal battle over abortion to the states, with some prohibiting the procedure and others moving to safeguard it.

As the nation’s post-Roe chapter begins, here are key facts about Americans’ views on abortion, based on two Pew Research Center polls: one conducted from June 25-July 4 , just after this year’s high court ruling, and one conducted in March , before an earlier leaked draft of the opinion became public.

This analysis primarily draws from two Pew Research Center surveys, one surveying 10,441 U.S. adults conducted March 7-13, 2022, and another surveying 6,174 U.S. adults conducted June 27-July 4, 2022. Here are the questions used for the March survey , along with responses, and the questions used for the survey from June and July , along with responses.

Everyone who took part in these surveys is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way nearly all U.S. adults have a chance of selection. The survey is weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories.  Read more about the ATP’s methodology .

A majority of the U.S. public disapproves of the Supreme Court’s decision to overturn Roe. About six-in-ten adults (57%) disapprove of the court’s decision that the U.S. Constitution does not guarantee a right to abortion and that abortion laws can be set by states, including 43% who strongly disapprove, according to the summer survey. About four-in-ten (41%) approve, including 25% who strongly approve.

A bar chart showing that the Supreme Court’s decision to overturn Roe v. Wade draws more strong disapproval among Democrats than strong approval among Republicans

About eight-in-ten Democrats and Democratic-leaning independents (82%) disapprove of the court’s decision, including nearly two-thirds (66%) who strongly disapprove. Most Republicans and GOP leaners (70%) approve , including 48% who strongly approve.

Most women (62%) disapprove of the decision to end the federal right to an abortion. More than twice as many women strongly disapprove of the court’s decision (47%) as strongly approve of it (21%). Opinion among men is more divided: 52% disapprove (37% strongly), while 47% approve (28% strongly).

About six-in-ten Americans (62%) say abortion should be legal in all or most cases, according to the summer survey – little changed since the March survey conducted just before the ruling. That includes 29% of Americans who say it should be legal in all cases and 33% who say it should be legal in most cases. About a third of U.S. adults (36%) say abortion should be illegal in all (8%) or most (28%) cases.

A line graph showing public views of abortion from 1995-2022

Generally, Americans’ views of whether abortion should be legal remained relatively unchanged in the past few years , though support fluctuated somewhat in previous decades.

Relatively few Americans take an absolutist view on the legality of abortion – either supporting or opposing it at all times, regardless of circumstances. The March survey found that support or opposition to abortion varies substantially depending on such circumstances as when an abortion takes place during a pregnancy, whether the pregnancy is life-threatening or whether a baby would have severe health problems.

While Republicans’ and Democrats’ views on the legality of abortion have long differed, the 46 percentage point partisan gap today is considerably larger than it was in the recent past, according to the survey conducted after the court’s ruling. The wider gap has been largely driven by Democrats: Today, 84% of Democrats say abortion should be legal in all or most cases, up from 72% in 2016 and 63% in 2007. Republicans’ views have shown far less change over time: Currently, 38% of Republicans say abortion should be legal in all or most cases, nearly identical to the 39% who said this in 2007.

A line graph showing that the partisan gap in views of whether abortion should be legal remains wide

However, the partisan divisions over whether abortion should generally be legal tell only part of the story. According to the March survey, sizable shares of Democrats favor restrictions on abortion under certain circumstances, while majorities of Republicans favor abortion being legal in some situations , such as in cases of rape or when the pregnancy is life-threatening.

There are wide religious divides in views of whether abortion should be legal , the summer survey found. An overwhelming share of religiously unaffiliated adults (83%) say abortion should be legal in all or most cases, as do six-in-ten Catholics. Protestants are divided in their views: 48% say it should be legal in all or most cases, while 50% say it should be illegal in all or most cases. Majorities of Black Protestants (71%) and White non-evangelical Protestants (61%) take the position that abortion should be legal in all or most cases, while about three-quarters of White evangelicals (73%) say it should be illegal in all (20%) or most cases (53%).

A bar chart showing that there are deep religious divisions in views of abortion

In the March survey, 72% of White evangelicals said that the statement “human life begins at conception, so a fetus is a person with rights” reflected their views extremely or very well . That’s much greater than the share of White non-evangelical Protestants (32%), Black Protestants (38%) and Catholics (44%) who said the same. Overall, 38% of Americans said that statement matched their views extremely or very well.

Catholics, meanwhile, are divided along religious and political lines in their attitudes about abortion, according to the same survey. Catholics who attend Mass regularly are among the country’s strongest opponents of abortion being legal, and they are also more likely than those who attend less frequently to believe that life begins at conception and that a fetus has rights. Catholic Republicans, meanwhile, are far more conservative on a range of abortion questions than are Catholic Democrats.

Women (66%) are more likely than men (57%) to say abortion should be legal in most or all cases, according to the survey conducted after the court’s ruling.

More than half of U.S. adults – including 60% of women and 51% of men – said in March that women should have a greater say than men in setting abortion policy . Just 3% of U.S. adults said men should have more influence over abortion policy than women, with the remainder (39%) saying women and men should have equal say.

The March survey also found that by some measures, women report being closer to the abortion issue than men . For example, women were more likely than men to say they had given “a lot” of thought to issues around abortion prior to taking the survey (40% vs. 30%). They were also considerably more likely than men to say they personally knew someone (such as a close friend, family member or themselves) who had had an abortion (66% vs. 51%) – a gender gap that was evident across age groups, political parties and religious groups.

Relatively few Americans view the morality of abortion in stark terms , the March survey found. Overall, just 7% of all U.S. adults say having an abortion is morally acceptable in all cases, and 13% say it is morally wrong in all cases. A third say that having an abortion is morally wrong in most cases, while about a quarter (24%) say it is morally acceptable in most cases. An additional 21% do not consider having an abortion a moral issue.

A table showing that there are wide religious and partisan differences in views of the morality of abortion

Among Republicans, most (68%) say that having an abortion is morally wrong either in most (48%) or all cases (20%). Only about three-in-ten Democrats (29%) hold a similar view. Instead, about four-in-ten Democrats say having an abortion is morally  acceptable  in most (32%) or all (11%) cases, while an additional 28% say it is not a moral issue. 

White evangelical Protestants overwhelmingly say having an abortion is morally wrong in most (51%) or all cases (30%). A slim majority of Catholics (53%) also view having an abortion as morally wrong, but many also say it is morally acceptable in most (24%) or all cases (4%), or that it is not a moral issue (17%). Among religiously unaffiliated Americans, about three-quarters see having an abortion as morally acceptable (45%) or not a moral issue (32%).

Final ‘Pregnant Workers Fairness Act’ Regulations Were Released—And It’s Great News for Women

A pregnant worker on a computer at her desk.

Today, the U.S. Equal Employment Opportunity Commission released its final regulations implementing the Pregnant Workers Fairness Act. The landmark statute mandating “reasonable accommodation” of workers’ pregnancy-related needs went into effect last summer, but the regulations explain the PWFA’s protections in more detail, providing additional guidance to workers, employers, and the courts so that the full force of the law is given effect.

That’s great news for workers like:

  • Michelle Durham , an Alabama Emergency Medical Technician forced onto unpaid leave during pregnancy because her employer refused to honor her doctor’s directive that she not lift heavy stretchers and patients;
  • Katia Hills , a retail worker from Indiana fired for absenteeism due to severe “morning sickness” and doctor’s visits; and
  • Jennifer Panattoni , a police officer from Illinois forced to take leave without pay when she was denied temporary reassignment to a desk job.

Michelle, Katia, and Jennifer aren’t alone; millions of people, especially Black and Brown women at greatest risk of maternal morbidity and mortality, labor in strenuous jobs that could be dangerous during pregnancy – like health care, retail, and law enforcement – yet are routinely denied the temporary modifications they need to stay healthy. One study estimated that 250,000 people annually don’t get the accommodations they need, putting them at risk for miscarriage and other poor health outcomes on the one hand, and job loss on the other.

So what did Congress intend the PWFA to accomplish?

As the first federal statute enacted in 45 years to protect on-the-job rights of pregnant workers, Congress passed the PWFA to fill a significant gap in existing law when it comes to accommodations – those temporary on-the-job modifications that a person may need to maintain their health or the health of their pregnancy. These changes can be minor – such as a slightly later start time to account for “morning sickness” or more frequent breaks for workers who spend long shifts on their feet – or more significant, such as suspension of risky duties, like repeated heavy lifting or exposure to toxins.

Although workers with disabilities have been entitled to such changes for more than 30 years under the Americans with Disabilities Act, pregnant workers have lacked similarly explicit protections. The PWFA eliminates the Hobson’s Choice faced by pregnant workers – i.e., continue working under unsafe conditions or leave the job altogether – by requiring employers to accommodate workers with limitations caused by “pregnancy, childbirth, or related medical conditions” unless doing so would impose an “undue hardship” on the employer’s business. Given the statute’s obvious benefits to workers and their families alike, it’s no wonder that the PWFA was enacted with exceptionally broad bipartisan cooperation that is virtually unheard of in today’s Congress, and with supporters as diverse as the U.S. Chamber of Commerce, U.S. Conference of Catholic Bishops, and the American Civil Liberties Union, my employer.

When the EEOC issued a draft version of its PWFA regulations last August, a small but noisy group raised the alarm that the agency had gone rogue. Why? The EEOC specifically stated that “pregnancy, childbirth, or related medical conditions” includes abortion, so that time off for abortion care – like time off for other doctor’s visits and medical procedures – is a “reasonable accommodation” required by the new statute. Critics contended that such a requirement improperly forces employers to somehow participate in their employees’ abortion decisions, which they claimed is unfair to employers that object to abortion on religious grounds.

The Historic New Law Protecting Fairness for Pregnant Workers

After a decade of advocacy, the Pregnant Workers Fairness Act is going into effect.

Source: American Civil Liberties Union

Such objections are likely to reemerge now that the EEOC’s final regulations are out, because abortion remains among the list of reasons entitling workers to reasonable accommodation. But while the EEOC’s noisy critics paint the agency as radical, it is they who push a fringe view – one that disregards nearly half a century of legal history. In 1978, Congress passed the Pregnancy Discrimination Act, a law protecting workers from discrimination based on “pregnancy, childbirth, or related medical conditions.” At the time, Congress made clear that it considered abortion to fall within that definition – meaning that firing or refusing to hire someone because they have had an abortion is unlawful discrimination. In 1979, the EEOC issued guidelines consistent with that interpretation and reaffirmed those directives in 2015, while in the four and a half decades since the PDA’s passage, numerous courts have reached the same conclusion: discrimination based on abortion is discrimination based on “pregnancy, childbirth, or related medical conditions.” The phrase also has been interpreted by judges to cover a wide range of pre- and post-partum reproductive needs, including the use of contraceptives, infertility treatment, and lactation. At the same time, the PDA makes clear that employers are not required to cover abortion in their health plans, and subsequent court cases have not disturbed that provision. When Congress copied and pasted “pregnancy, childbirth, and related medical conditions” from the PDA into the PWFA, all of that interpretive precedent came with it. The EEOC’s new regulations simply implement the law Congress actually passed.

When it comes to the rights of religious employers, abortion opponents also get an “F” in history. While such entities long have enjoyed certain narrow exemptions from our discrimination laws – and the PWFA does nothing to disturb such precedent – courts repeatedly have refused to grant religious employers wholesale immunity from these statutes. Indeed, Congress rejected an amendment that would have exempted religious employers from the PWFA’s reach altogether. The EEOC regulations rightly also refuse to rubber-stamp discrimination in the name of religion, instead providing careful, case-by-case consideration to instances where a religious employer objects to an employee’s need for accommodation under the PWFA, if any happen to arise.

Sadly, since 2022’s ruling in Dobbs v. Jackson Women’s Health Organization overturning Roe v. Wade , the time off of work that is necessary to get an abortion has increased exponentially. At last count, more than 20 states have either banned or severely restricted abortion. As a result, a sizable share of the U.S. population – millions of people – are now faced with the prospect of traveling hundreds of miles to even access this critically important healthcare. To name just one example, in Texas, where a near-total ban is in place, the average one-way trip for abortion has ballooned by more than eight hours – an increase of a full.

The PWFA is historic, but not because it applies to abortion. Employers already are prohibited from taking adverse action against workers who have abortions. The PWFA simply bars them from punishing people for taking time away from the job to obtain abortion care – or any other reproductive health care. No one should have to risk their paycheck to get the medical care they need – and thanks to the PWFA, they don’t.

How to Make a “Good” Presentation “Great”

  • Guy Kawasaki

what is presentation in pregnancy

Remember: Less is more.

A strong presentation is so much more than information pasted onto a series of slides with fancy backgrounds. Whether you’re pitching an idea, reporting market research, or sharing something else, a great presentation can give you a competitive advantage, and be a powerful tool when aiming to persuade, educate, or inspire others. Here are some unique elements that make a presentation stand out.

  • Fonts: Sans Serif fonts such as Helvetica or Arial are preferred for their clean lines, which make them easy to digest at various sizes and distances. Limit the number of font styles to two: one for headings and another for body text, to avoid visual confusion or distractions.
  • Colors: Colors can evoke emotions and highlight critical points, but their overuse can lead to a cluttered and confusing presentation. A limited palette of two to three main colors, complemented by a simple background, can help you draw attention to key elements without overwhelming the audience.
  • Pictures: Pictures can communicate complex ideas quickly and memorably but choosing the right images is key. Images or pictures should be big (perhaps 20-25% of the page), bold, and have a clear purpose that complements the slide’s text.
  • Layout: Don’t overcrowd your slides with too much information. When in doubt, adhere to the principle of simplicity, and aim for a clean and uncluttered layout with plenty of white space around text and images. Think phrases and bullets, not sentences.

As an intern or early career professional, chances are that you’ll be tasked with making or giving a presentation in the near future. Whether you’re pitching an idea, reporting market research, or sharing something else, a great presentation can give you a competitive advantage, and be a powerful tool when aiming to persuade, educate, or inspire others.

  1. Fetal presentation before birth

    Frank breech. When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head.

  2. Fetal presentation: Breech, posterior, transverse lie, and more

    Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. ... Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie ...

  3. Fetal Positions For Birth: Presentation, Types & Function

    Possible fetal positions can include: Occiput or cephalic anterior: This is the best fetal position for childbirth. It means the fetus is head down, facing the birth parent's spine (facing backward). Its chin is tucked towards its chest. The fetus will also be slightly off-center, with the back of its head facing the right or left.

  4. Fetal Presentation, Position, and Lie (Including Breech Presentation

    Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the presentation is vertex (head first), and the position is occiput anterior (facing toward the pregnant person's spine) and with the face and body angled to one side and the neck flexed. Variations in fetal presentations include face, brow, breech, and shoulder.

  5. Vertex Presentation: Position, Birth & What It Means

    The vertex presentation describes the orientation a fetus should be in for a safe vaginal delivery. It becomes important as you near your due date because it tells your pregnancy care provider how they may need to deliver your baby. Vertex means "crown of the head.". This means that the crown of the fetus's head is presenting towards the ...

  6. Abnormal Fetal lie, Malpresentation and Malposition

    Lie - the relationship between the long axis of the fetus and the mother. Presentation - the fetal part that first enters the maternal pelvis. Position - the position of the fetal head as it exits the birth canal. Other positions include occipito-posterior and occipito-transverse. Note: Breech presentation is the most common ...

  7. Presentation and position of baby through pregnancy and at birth

    Presentation refers to which part of your baby's body is facing towards your birth canal. Position refers to the direction your baby's head or back is facing. Your baby's presentation will be checked at around 36 weeks of pregnancy. Your baby's position is most important during labour and birth.

  8. Fetal Positions for Labor and Birth

    This presentation can lead to more back pain (sometimes referred to as "back labor") and slow progression of labor. In the right occiput posterior position (ROP), the baby is facing forward and slightly to the right (looking toward the mother's left thigh). This presentation may slow labor and cause more pain. Tips to Reduce Discomfort

  9. Delivery, Face and Brow Presentation

    The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin.

  10. Fetal Position

    Fetal position reflects the orientation of the fetal head or butt within the birth canal. The bones of the fetal scalp are soft and meet at "suture lines." Over the forehead, where the bones meet, is a gap, called the "anterior fontanel," or "soft spot." This will close as the baby grows during the 1st year of life, but at birth, it is open.

  11. Breech Baby: Causes, Complications, Turning & Delivery

    Breech is common in early pregnancy and most babies will move to a head-first position by 36 weeks of pregnancy. This head-first position is called vertex presentation and is the safest position for birth. Advertisement. Cleveland Clinic is a non-profit academic medical center.

  12. Breech Presentation

    Breech Births. In the last weeks of pregnancy, a baby usually moves so his or her head is positioned to come out of the vagina first during birth. This is called a vertex presentation. A breech presentation occurs when the baby's buttocks, feet, or both are positioned to come out first during birth. This happens in 3-4% of full-term births.

  13. Pregnancy Diagnosis: Overview, History and Physical Examination

    The classic presentation is in a patient with regular menstrual cycles who presents with amenorrhea and typical history and physical examination findings. Ultrasonography can be used to confirm a viable intrauterine pregnancy. Currently, most women are diagnosed with pregnancy after a missed menstrual cycle and a positive urine or serum hCG ...

  14. Abnormal Presentation

    Compound presentation means that a fetal hand is coming out with the fetal head. This is a problem because: The amount of baby that must come through the birth canal at one time is increased. There is increased risk of mechanical injury to the arm and shoulder, including fractures, nerve injuries and soft tissue injury.

  15. The evolution of fetal presentation during pregnancy: a retrospective

    Introduction. Cephalic presentation is the most physiologic and frequent fetal presentation and is associated with the highest rate of successful vaginal delivery as well as with the lowest frequency of complications 1.Studies on the frequency of breech presentation by gestational age (GA) were published more than 20 years ago 2, 3, and it has been known that the prevalence of breech ...

  16. Fetal Presentation, Position, and Lie (Including Breech Presentation)

    Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the presentation is vertex (head first), and the position is occiput anterior (facing toward the pregnant patient's spine) with the face and body angled to one side and the neck flexed. Abnormal presentations include face, brow, breech, and shoulder.

  17. A Guide to Posterior Fetal Presentation

    The posterior baby's back is often extended straight or arched along the mother's spine. Having the baby's back extended often pushes the baby's chin up. Attention: Having the chin up is what makes the posterior baby's head seem larger than the same baby when it's in the anterior position.

  18. Breech: Types, Risk Factors, Treatment, Complications

    At full term, around 3%-4% of births are breech. The different types of breech presentations include: Complete: The fetus's knees are bent, and the buttocks are presenting first. Frank: The fetus's legs are stretched upward toward the head, and the buttocks are presenting first. Footling: The fetus's foot is showing first.

  19. What is malpresentation?

    What are presentation and malpresentation? 'Presentation' describes how your baby is facing down the birth canal. The 'presenting part' is the part of your baby's body that is against the cervix. The ideal presentation is head-first, with the crown (top) of the baby's head against the cervix, with the chin tucked into the baby's ...

  20. Malpresentation and Malposition of the Fetus

    Face presentation Brow presentation . In most cases of a normal vertex (head down) presentation, the baby's head is flexed with the chin close to the baby's chest. In these cases, the presenting part is the occiput, the posterior part of the baby's head.

  21. What Is Malpresentation in Pregnancy?

    What Is a Presentation in Pregnancy? The term presentation refers to the position of the baby or how the baby is facing down in the birth canal. The ideal presentation is called vertex presentation, via the head first and the chin tucked into the baby's chest. This is the most favorable position for a vaginal delivery.

  22. What Are Compound Presentations?

    A prenatal presentation known as a compound presentation occurs when one extremity develops concurrently with the part of the fetus that is closest to the birth canal. A fetal hand or arm typically presents with the head during compound presentations. A presentation is considered compound when one or more limbs prolapse together with the head ...

  23. Key facts about abortion views in the U.S.

    The wider gap has been largely driven by Democrats: Today, 84% of Democrats say abortion should be legal in all or most cases, up from 72% in 2016 and 63% in 2007. Republicans' views have shown far less change over time: Currently, 38% of Republicans say abortion should be legal in all or most cases, nearly identical to the 39% who said this ...

  24. External Cephalic Version (ECV): Procedure & Risks

    External cephalic version (sometimes called ECV or EV) is a procedure healthcare providers will use to rotate a baby from a breech position to a head-down position. A breech position is when a baby's feet or buttocks present first or horizontally across your uterus (called a transverse lie). A baby changes positions frequently throughout pregnancy.
