Cesarean section damage to the reproductive system is mainly in the uterus, which may lead to uterine scar diverticula, placenta implantation, etc., as well as the possibility of post-surgical infections. A C-section requires an incision in the uterus to remove the fetus. It takes about two years for the uterine incision to heal after the surgery, and a scar will form after healing. Sometimes the scarred area in the lower part of the uterus does not heal well and a uterine scar diverticulum may form. Scarred uterine diverticula may cause menstrual disorders and symptoms of drenching menstrual periods. When a woman with a scarred uterus becomes pregnant again, if the placenta grows over the scar, placenta implantation may occur, increasing the chance of postpartum hemorrhage during another delivery. Postoperative infections and pelvic inflammatory disease may also occur after a cesarean section, which in turn affects the fallopian tubes and ovaries and may lead to secondary infertility or ectopic pregnancy.
