A large population-based study using health administrative data from Ontario examines whether endometriosis is associated with an increased risk of congenital anomalies in offspring — with findings that suggest increased monitoring may be warranted for affected pregnancies.
MedicalResearch.com: What is the background for this study? The study was conducted using health administrative data in Ontario. The data was from 2006 to 2021, which resulted in over 1.4 million mother-baby pairs. Endometriosis is an inflammatory condition where the uterine lining grows outside of the uterus, which can result in painful menstruation, intercourse and bowel movements. Roughly 10% of reproductive aged patients have endometriosis, and of those, 30–60% have infertility.
