internal pudendal artery

A branch of the internal iliac artery. The internal pudendal artery leaves the pelvic cavity through the greater sciatic foramen alongside the inferior gluteal artery, below the piriformis muscle; the artery then reenters the pelvis, running into the ischiorectal fossa via the lesser sciatic foramen. Its branches include the posterior scrotal, posterior labial, perineal, and inferior rectal arteries and the deep artery of the penis or clitoris, the dorsal artery of the penis or clitoris, and the artery of the bulb of the penis.

The indirect branch of the sciatic artery arises from the internal pudendal artery in male and from the superior gluteal artery in female (Table I).
[25] reported the origin of prostatic arteries as follows: internal pudendal artery (56%), common gluteal-pudendal trunk (28%), obturator artery (12%), and inferior gluteal artery (4%).
Among its branches, there are the superior gluteal artery, the inferior gluteal artery and the internal pudendal artery that go out from the pelvis through the greater ischiatic foramen to the gluteal region (Moore & Dalley, 2004).
In the extrapelvic course of the inferior gluteal artery was observed that one of its branches, called ischiatic artery, is a long and thin vessel that is related to the ischiatic nerve; and that the internal pudendal artery in this region sends only muscular branches to irrigate the muscles of this region (Williams et al., 1979).
In the anatomic piece was observed that this artery started from the internal pudendal artery and its caliber was larger than the ones observed in the pieces of routine studies, and its syntopy with the ischiatic nerve was also different from the ones found and described in the literature.
(1976) stated that the internal pudendal artery in the rabbit (Oryctolagus cuniculus) is the continued common iliac artery.
