Recurrent miscarriages happen when women have three or more consecutive miscarriages before reaching 20 weeks of pregnancy. This happens in between 0.5 and 1 percent of pregnancies.
At the Center for Fertility and Reproductive Endocrinology at Magee-Womens Hospital of UPMC, we will do a comprehensive evaluation to identify possible and likely causes for your recurrent miscarriages. This evaluation will include hormonal tests, endometrial biopsies, genetic studies, immunologic evaluations, and other imaging tests.
There are many possible causes for recurrent pregnancy losses. These include hormonal and metabolic concerns, such as undiagnosed thyroid diseases or unstable diabetes; abnormalities in the uterus, such as fibroids, polyps, and uterine septum; blood disorders; genetic abnormalities; and chronic uterine infections.
Managing recurrent miscarriages in an effort to carry a pregnancy to term focuses on treating the specific cause of the recurrent miscarriages. However, 50 percent of couples — despite a thorough evaluation — will have no identifiable cause for their multiple losses.
