Born With Half Uterus? Know Everything About Unicornuate Uterus From The Expert

There are so many things about our body that we ourselves do not know. The knowledge of these things only comes when we are diagnosed with a certain kind of disease or a condition. Unicornuate Uterus is something very similar. A genetic condition in which a person is born with just half of the uterus that means that person will have one fallopian tube instead of two. Here is everything that you need to know about Unicornuate Uterus with Dr. Yuvi Jadeja, Gynecologist and Fertility expert.

What is Unicornuate Uterus?

A rare genetic disorder that results in the formation or development of just half of the uterus. Unicornuate uterus, also known as the unicornis unicollis is a type of congenital uterine abnormality also termed as the mullerian duct abnormality. Due to this abnormality the uterus formed is smaller in size as compared to a normal uterus and has just one functioning fallopian tube instead of two.

Unicornuate uterus is something that a person is born with and hence it is congenital. Even though the condition is present from birth, a woman only comes to know about it once she tries to conceive in order to have a baby. This condition of the Unicornuate uterus occurs as there is  failure in one mullerian duct, due to which it is called the mullerian duct abnormality. As the failure in one duct is present the other one develops normally and may or may not have a rudimentary horn.  

Here Is what Dr. Yuvi has to say about this “As a uterus is formed due to the fusion of two malenian tubes, when one of these tubes are not formed it results in the formation or development of a very rare genetic condition where just half of the uterus is formed which is known as the unicornis or a hemi uterus. In this rare genetic condition, the size of the uterus is small and it has only one fallopian tube. This unformed fallopian tube might still stay as a rudimentary horn. This condition leads to complications in fertility and problems like miscarage, pain, breech delivery, abdominal pain, infertility, miscarage and other complications in pregnancy and delivery.”

What Causes a Unicornuate Uterus?

As now you know how the formation of a uterus takes place and what exactly a unicornuate uterus is. Let us take a step ahead and try to learn about the causes behind this condition and the reasons that give rise to a half formed uterus.

Being a congenital condition, unicornuate uterus is something which is present since the bith in a woman’s body and hence is directly affected by faulty genes. These genes give rise to an abnormal mullerian duct or a paired duct of the embryo. As the uterus is formed due to the fusion of these mullerian ducts, due to the abnormal development of these ducts, it results in the formation of just half of the uterus and only one functional fallopian tube.

What are the Symptoms of Unicornuate Uterus?

For any illness or condition, it is important to look out for the signs and symptoms in order to get an early diagnosis and timely treatment. Although Unicornuate uterus is a condition which is present inside a woman’s body since birth, here are some of the signs and symptoms that you can look out for in order to diagnose this disorder. 

  • History of infertility- As infertility is one of the biggest signs of unicornuate uterus, in many cases a woman only comes to know that she has been suffering from this condition when tries to conceive
  • Abdominal Pain- Some people also experience abdominal pain due to the presence of remnants of the other uterine.

  • Chronic Pelvic Pain- A chronic pelvic pain occurs in a condition where the functioning horn is very solid and is isolated from the rest of the uterus. This pain occurs due to the buildup of menstrual or period blood which does not get drained out through vagina.
  • Hematometra- A condition in which the blood gets accumulated in the uterus due to its inability to drain it out. This condition causes cramps in the pelvic and lower abdominal region along with frequent urination during periods.

Diagnosis of Unicornuate Uterus

One can get to know about the unicornuate uterus from the symptoms it comes with, but in many cases they get ignored and become unnoticed. Many women only come to know about unicornuate uterus only when they try to conceive a baby. This can be due to the repeated history of failed pregnancy like infertility, premature delivery, miscarrage, etc.

A doctor might take a person through the following procedure in order to diagnose the unicornuate uterine-

  • Laparoscopy- A surgical procedure through which the unicornuate uterine is diagnosed by inserting a fiber optic tool through the abdominal wall in order to have a clear vie of the organs inside.

  • Infertility test- Also known as the regular pelvic test, an infertility test includes the physical examination of organs like cervix, uterus, vagina, ovaries, recum, fallopian tubes, etc.
  • Hysteroscopy- Carried out by using a hysteroscopy, hysteroscopy is a procedure in which the examination of a uterus takes place. This is done by using a narrow telescope with light and camera attached to its one end. 
  • Imaging- In this process an MRI (Magnetic Resonance Imaging) with three dimensional sonography is performed as a normal sonography test often fails to diagnose this condition.
