How is Retrograde Menstruation Linked to Endometriosis?
Endometriosis is a condition where endometrial-like tissue grows outside the uterus, causing pain and possibly infertility. Retrograde menstruation is one of the proposed mechanisms for the development of endometriosis. When menstrual blood containing viable endometrial cells flows backward into the pelvic cavity, these cells can implant on the peritoneal surface or other organs. Once implanted, these cells can proliferate and form endometriotic lesions.
