Function[edit]
It helps flex the anus, and (in males) stabilize the erect penis or (in females) tense the vagina during orgasm. Kegel exercises (also known as pelvic floor exercises) can help tone the ischiocavernosus muscle.
Ischiocavernosus compresses the crus penis, and retards the return of the blood through the veins, and thus serves to maintain the organ erect.
Fibers[edit]
It arises by tendinous and fleshy fibers from the inner surface of the tuberosity of the ischium, behind the crus penis; and from the rami of the pubis and ischium on either side of the crus.
From these points fleshy fibers succeed, and end in an aponeurosis which is inserted into the sides and under surface of the crus penis.

- PURPOSE: The bulbospongiosus muscle is part of the superficial muscular layer of the perineum and pelvic floor. Its morphology remains controversial in the literature. Therefore, we reinvestigated the fascial arrangement and fiber courses of the bulbospongiosus muscle and its topographical relation

- AIMS: The purpose of the present study was to determine the contribution of the external urethral sphincter (EUS), the ischiocavernous (IC), or the bulbospongiosus (BS) on the control of micturition, copulatory behavior and semen expulsion in male rats. We hypothesized that the EUS contributes to ma
