ORIGIN:  Part of pubococcygeus of the levator ani. It is at the inner aspect of puborectalis which takes origin from the inner aspect of pubis.

 

INSERTION:  Sides of the vaginal wall.

 

ACTION:  Forms part of pelvic floor (or diaphragm). The pubovaginalis is an important voluntary sphincter of vaginal wall assisting the non-pelvic floor voluntary sphincter known as the sphincter vaginae in the deep perineal pouch of the female. When well developed, this pelvic floor sphincter assists vaginal sexual climax probably because it increases contact with penis at intercourse. It also helps to cure stress incontinence, especially after childbirth in the so-called Kegelís exercises.

 

NERVE:  Nerve to levator ani from sacral and coccygeal nerves and the inferior rectal nerve
