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.
