Charles B. Penrose, A Text-book of Diseases of Women
“ Extreme uterine prolapse sometimes occurs in a nulliparous woman in whom the perineal supports are naturally weak. In such women there exists a condition of relaxation identical in results with subcutaneous laceration of the perineum.Anything that increases the specific gravity of the uterus will make it sink somewhat lower in the pelvis. Subinvolution, congestion from inflammation, or retroflexion may do this. In such cases, however, the prolapse never becomes extreme, rarely extending beyond a slight sinking of the uterus. ”
