OB-GYN (Obstetrician-Gynecologist) Questions Unicornuate uterus

What is a unicornuate uterus?

I had a severe problem with my first pregnancy several years ago due to a unicornuate uterus. Is there a type of surgery that can help me with this? What does it mean to have an unicornuate uterus?

Normally the uterus has 2 cornes 1 on each side.
The unicorn uterus has only one corn.
Unicornua uteri is an abnormal congenital uterus which occurs during embryonic development in the mullerian duct system. Its features include a single tube of fallopio with a contralateral side of a rudimentary horn.
The uterus is an organ formed from a left and right parts that fuse into one unit. Occasionally this union fails and the resulting uterus is made up of two separate parts (horns) or only one part. This means that the space for the fetus to grow is restricted and of course there is only one main artery to the uterus rather than a lady and right blood supply. Pregnancy losses are higher in this scenario but many women with this condition can have successful pregnancies. You need to seek advice and care from a specialist on-gun.
During normal development, the uterus is hardest, which joins and sometimes one hard is bigger and that is a unicorn uterus.
There are 2 parts during your development to form the uterus, but there is a group of uterine anomalies that can occur if these 2 parts do not form the way they are supposed to. Bicornuate uterus has 2 “horns” or halves that didn’t completely join to make the typical uterus, a uterine didelphis has 2 uterine horns, 2 cervix , unicornuate- only one goal for horn forms fully, the other half is there but so small it is not functional- called a rudimentary horn- the other half can function but cause pregnancy complications. Hope this helps- you can search uterine anomalies to see pics of these defects.
You need to speak to an Ob/Gyn regarding this issue. Your uterus forms from 2 tubes that come together and the middle dissolves. For whatever reason, you only developed 1 tube. Your uterus will have less muscle mass and stretching capabilities. So, if/when you get pregnant, it puts you at risk for preterm contractions/labor and your baby facing the wrong direction. From a gyn standpoint, it puts you at risk for endometriosis where the lining of the uterus gets into your abdomen and causes pain, pain with cycles, and pain with intercourse. Most of the time, you do not know your uterus is even abnormal until you have a baby.
