Although there are many potential causes of PID, gonorrheal infection is one of them. Chronic Inflammation of the uterine tubes can occlude them resulting in infertility. Prolapsed uterus - the uterus is almost directly above the vagina. In fact, the cervix, the neck region, of the uterus extends into the upper vagina. Ligaments hold the uterus in proper position so that it does not prolapse or herniate into the vagina.
Severe prolapse can result in the uterine cervix protruding from the vaginal opening.
Surgical repair is typically required to restore the uterus to its proper anatomical position.
