On the off chance that these muscles or tendons stretch or end up feeble, they're never again ready to help the uterus, causing prolapse. Uterine prolapse happens when the uterus hangs or slips from its typical position and into the vagina (birth trench). Uterine prolapse might be inadequate or complete. Uterine prolapse happens when pelvic floor muscles and tendons stretch and debilitate and never again give enough help to the uterus. Therefore, the uterus descends into or juts out of the vagina.
