Pregnancy and trauma incurred during childbirth, particularly with large babies or after a difficult labor and delivery, are the main causes of muscle weakness and stretching of supporting tissues leading to uterine prolapse. Loss of muscle tone associated with aging and reduced amounts of circulating estrogen after menopause also may contribute to uterine prolapse. In rare circumstances, uterine prolapse may be caused by a tumor in the pelvic cavity.
