Structure
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.
Function
It helps (in males) stabilize the erect penis and (in females) tense the vagina during orgasm.
Ischiocavernosus compresses the crus penis, and retards the return of the blood through the veins, and thus serves to maintain the organ erect.
