Dear animavibrante -
It is difficult for me to answer this without seeing the studies, but my guess is that if there is nothing obvious, like a large septum or a definite fibroid in the uterine cavity, that a uterine abnormality is unlikely to be causing your miscarriages. Arcuate, bicornuate, or T-Shaped uteruses are commonly seen, and although a bit controversial in my opinion do not cause recurrent miscarraiges. MRI should be very accurate.
Are you seeing a reproductive endocrinologist/infertility subspecialist? Have you been tested for other causes of miscarriages (chromosome studies/karyotype, testing for lupus anticoagulant and cardiolipin antibodies, etc)
How many miscarriages have you had? A Danish study from the early 1990s showed that even after three miscarriages the chance that the 4th pregnancy would be normal exceeded 50%, so there is definitely still hope!
Dear Dr. Plosker:
Thank you for your reply. I am currently seeing a reproductive endocrinologist and he's planning a hysteroscopy soon. There is a definite submucosal fibroid within the uterine cavity, along with several polyps.
I had a chromosome test done (from my recent miscarriage), anticoagulant and cardiolipin antibodies tests, and they came back normal. In fact, the only test that came back abnormal is a Factor V test (positive for one copy). Could this cause my early miscarriages?
Thanks.
