Unicornuate Uterus Treatment, Causes & its Type

Explain about Unicornuate Uterus

A unicornuate uterus is a rare genetic abnormality in which one-half of the uterus is present. The uterus is smaller in size and differently shaped than a normal uterus.

Also, in this condition, only one fallopian tube is present. The estimated prevalence of this congenital uterine anomaly in women ranges from 2 to 4 per cent.

Usually, when a female baby is in the womb as an embryo, a developing embryo will form two Mullerian ducts. Typically, the two fallopian tubes and uterus develop from these ducts. The uterus, which resembles a pear, is created when they unite in a symmetrical pattern.

In the incidence of a unicornuate uterus, there are two Mullerian ducts. However, one develops into a partial uterus with one functioning fallopian tube; the other is either entirely absorbed by your body or remains underdeveloped and assumes the shape akin to a rudimentary horn (hemi-uterus).

Unicornuate Uterus with Rudimentary Horn

A unicornuate uterus can also exist without a rudimentary horn. But according to research, a rudimentary horn is present in around 75 per cent of women.

The rudimentary horn may or may not be linked to your unicornuate uterus or have a functional uterine lining for menstruation. If the rudimentary horn is connected, it is called a communicating horn. Otherwise, when it is not connected, it can obstruct the flow of menstrual blood out of your body, leading to painful menstruation.

Moreover, a unicornuate uterus can cause you to have complications during pregnancy and miscarriages.

Treatment of unicornuate uterus

If you are experiencing pelvic pain, painful menstruation, difficulty conceiving or frequent miscarriages, and as a result, have been diagnosed with a unicornuate uterus. It can feel excruciating, frustrating and just too much at times.

But do not worry – unicornuate uterus treatment methods are available depending on the type and severity of your case and consist of the following:

Laparoscopic Surgery

An unconnected hemi-uterus leads to the buildup of menstrual blood and causes severe abdominal pain. So, this treatment method is used to extract a solitary hemi-uterus surgically.

Cervical Stitch

Also known as a cerclage, it involves stitching and closing your cervix during pregnancy. In case you are at a high risk of premature delivery, miscarriage or have an incompetent cervix, this procedure is recommended.

Moreover, a study reports that cervical cerclage is an effective treatment for unicornuate uterus.

Assisted Reproductive Technology

It consists of techniques that can help you conceive a baby if you have difficulty conceiving or are infertile. Treatments like In vitro fertilisation (IVF) or intrauterine insemination can prove beneficial.

According to a study, in comparison to the control group’s 65.7 per cent, 53.1 per cent of women with a unicornuate uterus became pregnant after completing one IVF cycle.

Specialised Care

A unicornuate uterus pregnancy is often accompanied by complications like pre-term delivery, breech (feet first) delivery, etc. So, special care and caution needs to be taken at all times to minimise the risk.

Symptoms of unicornuate uterus

In case the rudimentary horn is connected to the uterus and cervix, you may not experience symptoms of a unicornuate uterus. Even when a rudimentary horn is not present, you may remain asymptomatic.

This genetic condition can remain undetected until you have difficulty becoming pregnant and undergo imaging tests like unicornuate uterus ultrasound.

On the other hand, if the rudimentary horn is present and not connected to the uterus, you can experience the following unicornuate uterus symptoms:

  • Severe pelvic pain
  • Painful menstruation
  • Premature birth
  • Hematometra (accumulation of blood in the uterus)
  • Miscarriages during pregnancy
  • Difficulty conceiving


Types of unicornuate uterus

There are variations in the way a unicornuate uterus manifests itself. And the four different unicornuate uterus types are mentioned below:

Types of unicornuate uterus

  • No rudimentary horn: It refers to a unicornuate uterus which does not consist of a rudimentary horn. It is common and does not result in any unpleasant symptoms.
  • A rudimentary horn without cavity: In this type, a rudimentary horn is present with a unicornuate uterus. But since it lacks a lining, there is no blood buildup. It is also known as a horn with no endometrial cavity and does not cause distressing symptoms.
  • Communicating rudimentary horn: In this type of unicornuate uterus, a rudimentary horn is connected with your uterus. It enables menstrual blood to flow freely from the horn to the uterus and out of your body.
  • Non-communicating rudimentary horn: In this type, a rudimentary horn is not linked with the unicornuate uterus. It impedes the blood flow to your uterus and out of your body and, as a result, causes extreme pelvic pain.

Ultrasound for unicornuate uterus

To check for the diagnosis of a unicornuate uterus, a doctor asks questions about comprehensive medical history. A pelvic exam and physical exam are conducted to rule out other factors.

The doctor may also recommend a 3D ultrasound, as it can show the uterine structure. However, sometimes, it fails to detect unicornuate uterus, so an MRI scan is also advised to double-check the diagnosis.


Besides these, hysterosalpingogram, laparoscopy, and hysteroscopy are suggested to check for unicornuate uterus.

A hysterosalpingogram involves inserting a dye into the uterus through the cervix, followed by x-rays that show the uterus and fallopian tubes. A laparoscopy involves an extensive assessment of the uterus. A hysteroscopy is an examination where the doctor puts a small telescope into the cervix to assess the uterus.

Ans. It is possible to fix a unicornuate uterus through the various treatment methods mentioned above.
