Urogenital prolapse, also known as pelvic organ prolapse (POP), occurs when the muscles and tissues supporting the pelvic organs (such as the bladder, uterus, and rectum) weaken, causing one or more of these organs to drop or press into or out of the vagina. This condition is common among women, particularly those who have had multiple vaginal deliveries, are postmenopausal, or have other risk factors.
