Overview

A septate uterus is a deformity of the uterus, which happens during fetal development before birth. A membrane called the septum divides the inner portion of the uterus, at its middle. This dividing septum is a fibrous and muscular band of tissue that can be thick or thin.

A septate uterus is a congenital condition in which a thin membrane called a septum divides the uterus, either partially or completely. While the condition does not affect a woman’s ability to conceive, it can impact a pregnancy outcome. Some women who have a septate uterus don’t realize there’s an issue until pregnancy when an ultrasound can point to the problem. Unfortunately, there’s a higher risk of miscarriage so recurrent pregnancy loss may also be what made you realize there was an issue.

It’s possible for a septate uterus to be misdiagnosed as a bicornuate uterus. A bicornuate uterus is one that is heart shaped. In this condition, the top portion of the uterus, or fundus, dips in towards the midline of the uterus. This dip can range from shallow to deep. A bicornuate uterus does not typically affect a woman’s chances of successful pregnancies unless the dip is extreme. There are also rare cases of a bicornuate uterus and a septate uterus occurring together.

How does a Septate Uterus affect pregnancy?

A septate uterus does not typically affect a woman’s ability to conceive, but it does significantly increase their risk of a miscarriage. Women with septate uteri can also go on to have recurrent miscarriages.

The rate of miscarriage in the general population is around 10 to 20 percent in women who know they are pregnant. The estimated rate of miscarriage in women with septate uteri is thought to be between 20 to 25 percent. Some research shows it may be as high as forty percent.

A septate uterus is believed to be the most common type of abnormal uterine development. It’s estimated that over half of developmental problems of the uterus involve a septum.

Women with a septate uterus have an increased risk of both miscarriage and recurrent miscarriage. Pregnancies that occur within a uterus with any type of abnormal development increase the risk for:

  • Premature labor
  • Breech Positions
  • C-Section Delivery
  • Bleeding complications after delivery

 

What are the symptoms of a septate uterus?

  • unusual pain before or during a menstrual period.
  • a tampon may not prevent menstrual blood from leaking out.

 

What causes septate uterus?

  • A septate uterus forms during embryological development when the tubes that eventually become one uterus don’t fuse together properly.
  • The cause of this genetic abnormality is unknown.

 

Will a septate uterus affect sexual and reproductive life?

  • Having a septate uterus doesn’t affect a woman’s sexual pleasure or fertility.
  • Women with a septate uterus can have a normal reproductive life, but it may add complications to pregnancy.

 

How is it diagnosed?

A septate uterus often remains undiagnosed until a woman experiences repeated miscarriage. At other times, the doctor may stumble upon it during a routine physical exam. This is because is a septate uterus is often accompanied by similar malformations of the cervix and vagina. Typically referred to as a “double cervix” and “double vagina,” these are often the first clues of a similar abnormality in the uterus.

Doctors will begin the investigation with either an ultrasound or magnetic resonance imaging (MRI) scan. A definitive diagnosis may require on a hysterosalpingogram (an X-ray procedure highlighting the uterus) and/or hysteroscopy (a visual examination using a lighted scope).

Even with these examinations, a septate uterus can sometimes be misdiagnosed as a bicornuate uterus, also known as a “heart-shaped uterus.” While the malformation is by no means considered normal, it does not typically increase the risk of miscarriage.

Treatment

A septate uterus is treated with surgery, most commonly by removing the septum during a hysteroscopy. This is a fairly minor procedure usually performed on an outpatient basis.

The surgery, called metroplasty, is minimally invasive and involves the insertion of a medical device through the cervix and into the uterus to cut away excess tissue. This can be usually be performed in between 30 and 60 minutes. Antibiotics and estrogen may be prescribed afterward to prevent infection and aid in the healing.

Hysteroscopic metroplasty can improve chances of a successful pregnancy in women with recurrent pregnancy by 53.5 percent, according to a comprehensive analysis of 29 studies conducted from 1986 to 2011.

It is unnecessary to women with a septate uterus who have no intention of getting pregnant. On its own, a septate uterus poses no risk for cancer.
