Recurrent miscarriage should be distinguished from sporadic pregnancy loss that implies intervening pregnancies that reached viability. Maggie Donovan, PA-S2. University of South Dakota . Physician Assistant Studies Program. Recurrent pregnancy loss (RPL) is an important issue in reproductive health and is commonly defined as two or more clinically recognized failed pregnancies before 20 weeks of gestation. Recurrent pregnancy loss has been found to affect 1%-5% of couples trying to conceive and the mechanism of nearly 50% of cases of RPL remains unknown. Generally accepted mechanisms of RPL include uterine abnormalities, immunologic factors such as antiphospholipid antibody syndrome, and genetic abnormalities. Some hypothesized mechanisms that remain controversial are endocrine factors, inherited thrombophilia disorders, paternal sperm abnormalities, infections, environmental, and psychological factors. This review evaluates past and current research to assess which mechanisms are empirically supported as underlying causes of recurrent pregnancy loss. . Mark Hasegawa-Johnson. April 6, 2020.
