Anomoly.  Congenital.  Rare – in my case occurring in 0.1-0.5% of women or possibly as high as 10% in women with recurrent pregnancy loss[1].

On Monday I had a hysterosalpinogram (HSG) done to check the lining of my uterus for abnormalities potentially caused by a cesarean section in 2004.  My doctors and I are not finding good reasons for repeat pregnancy loss.  My lupus anticoagulant panel came back clean, and the only test left to do in my current OB’s mind is an ANA.

As a result of the HSG, I was diagnosed with uterus didelphys, one of several Mullerian Anomalies.  The OB is certain that this is the cause of my recurrent losses though still recommends the ANA blood draw.  He doesn’t think I need to proceed with a thrombophilia panel.  He didn’t offer any course of action for this issue, suggesting that we should just “keep trying.”  He was surprised that this hadn’t been diagnosed sooner.

Of course, being the curious person that I am, I performed internet searches for “double uterus,” “didelphic uterus,” and “uterus didelphys.”  I also chatted with an internet friend who put me in touch with a couple of other people who have been diagnosed with anomalies.  I have joined a yahoo group that deals specifically with these anomalies.  Even a couple of hours after the procedure, having looked at many pictures on the internet, I began to have doubts about my diagnosis.

I will obtain a copy of my HSG “picture” hopefully today from the radiology lab.  When I compare what I remember seeing on the screen at the hospital with what I see on the internet, I think it’s more likely that my uterus is bicornuate (heart shaped) and/or possibly contains an uterine septum.  A septum would be most problematic for maintaining a pregnancy because if the baby implants on the septum, it will not have enough vascular support to grow.  (This just breaks my heart.)

What next?  I am going to be in Denver for a couple of months studying vocology (vocal science).  (I need a calculator and to remember my college physics class from 1990, eek.) I am looking for a reproductive specialist there who will do a thorough investigation of immunological, endocrine, and structural causes for my losses.  It is possible that the immunological path has been exhausted, but with my mother’s history of autoimmune disease, I’m not so sure.  Endocrine/hormone issues haven’t been addressed to my satisfaction.  Neither OB group I have worked with in town believe in progesterone deficiency.

So, that’s my story in a nutshell for now.

[1] Müllerian duct anomalies are estimated to occur in 0.1-0.5% of women. The true prevalence is unknown because the anomalies usually are discovered in patients presenting with infertility. Some women carry babies to term with anomalies, so it could be more common, possibly as high as 3% of all women.  Sources:;
