Causes Of  Bicornuate Uterus

A bicornuate uterus will develop in a woman from the womb itself. It is congenital, which means a woman with a heart-shaped uterus will be born with the condition. It will take 10 to 20 weeks of pregnancy for the development of a fetal uterus. Mullerian ducts merge to form a uterine cavity.

When it comes to the bicorn uterus, the two ducts called the Mullerian ducts will not fuse completely. This abnormality in the merging process will result in the development of two uterine cavities while giving the uterus a deep heart shape. Besides, there is no chance of genetic transfer of the condition. Even if you have a bicornuate uterus, you can not pass the bicornuate uterus to your offspring. It is not a genetic condition.

The Types Of Bicornuate Uterus

There are two common types of bicornuate uterus. The classification is made based on the depth of the uterus dip. Common types of bicornuate uterus are,

Types Of Bicornuate Uterus
  • Partial Bicornuate Uterus – The fetal uterus develops when two mullerian ducts combine. But in the bicornate uterus, the Mullerian duct will not merge properly and forms two uterine cavities. When the degree of separation between the two cavities is less it is called partial bicornuate uterus. Your uterus will have the shape of the heart but the uterine dip will be less severe.
  • Complete Bicornuate Uterus –  In a complete bicornuate uterus the separation between two uterine cavities will be deeper and severe. It will give the uterus a deep heart shape.

A medical professional will be able to tell you what type of bicornuate uterus you have.

Diagnosis Of Bicornuate Uterus

A doctor will suggest imaging and other diagnostic tests after a careful assessment of your symptoms and pelvic exam. If you are pregnant, a regular ultrasound scan finds the presence of a bicornuate uterus. Ultrasound and MRI are the two common tests recommended for the diagnosis of the bicornuate uterus. A doctor may suggest an MRI to get a more detailed image of the uterus.

The Treatment Options 

Surgical procedures can treat bicornuate uterus. However, surgery is not recommended for all bicornuate uterus cases. A doctor may opt for surgery in rare cases. A surgery can fix the shape of the uterus. A minimally invasive surgery called, Strassman metroplasty is carried out laparoscopically to treat the bicornuate uterus.

The surgery will correct the shape of the uterus by removing the tissue that separates the uterine cavities. After metroplasty, your doctor may recommend to wait three to four months to get pregnant. Bleeding, infections, and scarring are the common risk elements involved in the surgery. Your doctor will explain all the process and risk elements of the surgery prior to the procedure.  During pregnancy, your doctor will also prescribe medicines to reduce the pain and discomfort.
