Which Placenta Position is Best for Vaginal Labor?
At Stork Helpers, we spend a good amount of time talking about the power of the placenta and the health benefits it provides both before and after labor. Why? Because it is powerful!
The placenta is the organ responsible for the transfer of nutrients and oxygen to your baby during pregnancy. Additionally, after birth, the placenta can be processed and consumed to reduce the negative impact of postpartum depression and help make milk production easier for mama.
The placenta develops as your baby develops. However, many mamas do not know that it can grow attached at different points in the uterus. Additionally, the placement of the placenta in the uterus can determine the ease of your labor and your baby's birth.
In this post, Stork Helpers will walk you through the development of the placenta, and the best placental position for vaginal labor.

The Developmental Stages of the Placenta
When you are pregnant, your attention is fixed on the health of your baby. You probably haven’t given your placental development more than a passing thought.
Let’s quickly look at how the placenta develops as that will determine its ultimate position at the time of labor.
The placenta first begins to grow when the blastocyst implants itself in your uterus. The blastocyst, the clump of cells that will eventually develop into the embryo, is called the inner cell mass. An outer cluster of cells forms too called the trophoblast, and these cells eventually become the placenta.
The trophoblast grows rapidly and forms two distinct layers: the inner cytotrophoblasts and the outer syncytiotrophoblasts.
The placenta at last forms when a fertilized egg plants itself on the uterus.
According to the Cleveland Clinic, there are several places the placenta can form during pregnancy.
- Posterior: closest to your spine
- Anterior: closest to your abdomen.
- Low-lying: towards the bottom of the uterus, covers all or part of your cervix
- Lateral: on the left or right side of your uterus
- Fundal: at the top of your uterus
Different placenta placements can affect your pregnancy and the ease of your labor and baby’s birth. Let’s explore that topic in the next section.

Which placenta position is best for vaginal birth?
Let’s break down each placenta position and discuss how it may affect your labor.
Posterior Placement
Your placenta has implanted itself on the back of your uterus. You will feel your baby's movements earlier and stronger. In addition, posterior placement allows your baby to get into an optimal placement for birth. Posterior placement is extremely common and often leads to vaginal birth.
Anterior Placement
Your placenta is attached to the front of your uterus. Anterior placement usually does not negatively affect your pregnancy or birth. However, it may be harder to feel your baby as it is better cushioned. Since your baby’s spine is against your spine, the labor may be more intense than in other positions. Additionally, there may be increased health risks due to anterior placement, but these are rare. Discuss with a professional for more information.
Low-Lying Placement
This occurs when the placenta develops close to or over the top of the cervix.
According to the UK's Nation Health Service, a low-lying placenta affect 1 in 200 births, and for 9 out of 10 women, the placenta moves upwards around 32 weeks.
A low-lying placenta comes with an increased risk of bleeding, and if the placenta blocks the uterus, the baby will need to be born via a caesarian section.
Lateral Placement
Your placenta is attached to either the right or left side of your uterus. In this placement, the uterus gets uniform blood flow from one of the uterine and/or ovarian arteries. This means the risk of pre-eclampsia is increased, but outcomes during labor and usually not affected. Lateral placements are the least common position.
Fundal Placement
Your placenta is attached to the top of your uterus. When the placenta is located here, it creates the weakest point of membrane over the cervix and can lead to premature rupture of membranes. Additionally, fundal placement has been linked to having a shorter third stage.
What are the stages of placental birth?
The placenta birth process is the third stage of birth. It is the process where after your baby is born, the placenta exits your body, and the birth process is complete.
Below are the steps of the placenta birth.
- Oxytocin is released by the posterior pituitary gland to regulate your contractions. This occurs before your baby is born.
- During childbirth, the blood from the placenta drains into the baby and the placenta is greatly reduced in volume.
- After the baby is born, the contraction pattern is interrupted because the uterus is suddenly empty and must return to its pre-pregnancy size.
- After about two minutes of rest, contractions will continue about every three to four minutes. These post-birth contractions allow the uterus to expel the lingering placenta and then return to its pre-pregnancy size.
- As contractions expel the placenta after childbirth, blood vessels within the placenta will be exposed and mama will begin to bleed naturally. Bleeding stops as soon as the uterus shrinks to the point where the exposed area has been sutured close.
