Q&A: What is a bicornuate uterus?

I was recently diagnosed with a bicornuate uterus. Can you tell me more about this condition and what methods should we use in hopes of success?

The Bump Expert

There are many uterine (womb) abnormalities. Bicornuate uterus literally means "two horns," and refers to a congenital uterine formation problem.

Embryologically, the uterus is formed beginning at five weeks of gestation. It starts out near the kidney as two separate structures called horns, then migrates down into the pelvis as the two horns fuse into one. The area of fusion is a septum dividing the two, and is reabsorbed to make a normal intrauterine cavity. Sometimes, however, this normal progressions does not occur.

A true bicornuate uterus is one in which the two horns migrate down but do not completely fuse to make a normal uterus. A more common abnormality is a septate uterus. This is an abnormality in which the uterine horns fuse completely, but the intervening septum is not completely absorbed. The uterus then appears as two horns internally, but externally looks to be unified.

A septate uterus may be associated with miscarriages, while a true bicornuate uterus is generally associated not with miscarriages, but a higher risk of preterm labor and birth. A noninvasive procedure called a pelvic MRI can differentiate these two conditions and other uterine congenital abnormalities.

Both abnormalities can be approached surgically. A septate uterus can be repaired with a day surgical procedure walled an operative hysteroscopy with septum resection. A true bicornuate uterus can only be approached through a more major surgery called a Strassman procedure, which requires an abdominal incision.

I was also diagnosed with a bicornuate uterus after my third miscarriage. I unfortunately had two more after that. The doctor wanted to perform the Strassman procedure and we had it scheduled only to find out at my pre-op appt. that I was pregnant. This one stuck and I delivered a baby girl on 9/11. Unfortunately, she was breach, which is common with the bicornuate uterus, and because of the way they had to perform the c-section I can't have anymore kids. I was blessed with a beautiful son and daughter and thank God everyday for my miracles. Be prepared for a difficult road and try not to smack the nurses who tell you how cool it is that you have a double uterus.

Q&A: What is a bicornuate uterus?

I was diagnosed with a Bicornuate uterus whn I was 4 months pregnant with my first child in 1995. Also to find out I was born with 1 kidney. 2 kids later ( 1 full term the second was 2 1/2 months premie ) and 1 on the way now , I'm 8 weeks pregnant.. Just a few months ago I had a miscarriage at 9 1/2 weeks so crossing my fingers. I went back to the Dr.s and they said they really can't call mine a bicornuate uterus because it splits down the middle ~ but ~ unlike others it has a very small gap inbetween both sides. FYI they said I could get pregnant on either side but history of all pregnancy has been on the right side.

Q&A: What is a bicornuate uterus?

I was diagnosed with a bicornuate uterus when I was 21, after I miscarried at 12 weeks. I was told that surgery at that young age wasn't wise, and that to wait until I was older and trying for a family. One year later I miscarried again. Since that time I've been nervous and scared of needing to 'try again'. Now, at 29, my FI and wanted to be sure we could have a family before it was time to try, so we got referred to an infertility specialist who hasn't hesitated to operate. I'm waiting for a surgery date now, and she is confident that I will have no problems conceiving and carrying afterwards. I do have a question though. For those of you who have carried successfully on the right or left side, does it look different? Are you off balance? Is there less room for the baby's growth? Was your balance more affected, or did you simply adapt the way you would if it were a normal pregnancy?

Q&A: What is a bicornuate uterus?

I was just diagnosed with a bicornuate uterus this passed week. My midwife acted like it wasn't a big deal and didn't provide much information. Now I'm starting to worry. I'm only 11 weeks pregnant. Maybe I should switch to one of the doctors in the practice? I definitely need more information!

Q&A: What is a bicornuate uterus?

I found out several years ago (by accident) that I have a bicornuate uterus and one kidney. I am 36 weeks! My baby is in the right horn. I have had ultrasounds bi-weekly for most of my pregnancy and was put on bedrest at 30 weeks because my cervical length was shortening and my fluid was low. My baby is also breech which is very common with this condition. My doctor is scheduling my c-section to be in my 37th week. It's very reassuring to me to read about all of your stories. From all of the research I have done on the topic, it's very clear that every woman with a bicornuate uterus has a different outcome simply because no two uterine abnormalities are exactly the same. It's been very challenging to find information, so Im appreciative to all of you for sharing your stories. Good luck to you all!

Q&A: What is a bicornuate uterus?

I just miscarried at 7 weeks, two days before my first ultrasoud. I found out during the ultrasound that i have a biornuate uterus (and yes, the nurse just thought that was the coolest thing for some reason). I've gotten mixed reactions from the docs in my practice and wasn't sure how big of a deal this was. Just had a D&C yesterday and after the surgery my doc told me that he absolutely wants to do an MRI to see the exact shape of my uterus to determine if surgery is necessary. Crosing my fingers that the "abnormality" is small enough that I can just start TTC again in a few weeks.

I think that it all depends on your medical examination. My aunt was wrongly diagnosed and she later needed for the services of a Mirena recall lawyer. I read in a magazine that this abnormality can be solved by a medical intervention.

I was recently diagnosed with a bicornuate uterus after having 3 full term, healthy, natural deliveries, not to mention 2 miscarriages. I am now 8 weeks pregnant and just now diagnosed with a bicornuate uterus. My kids are 11, 8, and 7. I know the probable cause of my previous miscarriages and as of today have been told to be on "bed rest" due to a threatened miscarriage. So for me I've seen it's been about 50/50, I've lost some but the full term pregnancies I had were completely normal.

Q&A: What is a bicornuate uterus?

Hi all. I wanted to quickly share my experience and give hope to those who have been diagnosed with a bicornuate uterus. I delivered a healthy boy this past May and had a very uneventful pregnancy after being diagnosed with a bicornuate uterus at the beginning of my pregnancy. I was really scared when I first found out after reading various articles and boards online. Try to resist doing this- they will tend to only scare you and often contain inaccurate information or stats. My OB-GYN who has been in the field for quite some time at a nationally-renowned hospital as well as my perinatologist (the top in the nation!) said not to worry from early on. My OB-GYN said she had never seen this condition cause any problems with the pregnancy and the perinatologist said it's generally only a problem if the embryo implants on the septum, in which case the pregnancy will terminate early on (but this is rare!!). And once you have a healthy pregnancy with this condition, it is unlikely you will suffer any ill effects in the future. In fact, as in my case, the septum can ultimately be destroyed as the uterus stretches to accommodate your growing baby. So try to not worry!!!
