Internal Pudendal Artery

Peer Review Status: Internally Peer Reviewed


The internal pudendal artery may arise in common with the obturator or the umbilical.

It may end as a perineal artery, with the artery to the penis arising from the internal iliac.

In some cases, it splits into two vessels, one of which remains in the pelvis to supply pelvic viscera.

The internal pudendal is necessarily, always a branch of the anterior division of the internal iliac artery.

The dorsalis penis artery may arise from profunda femoris or femoral artery.

The inferior rectal artery is typically a branch of the internal pudendal artery.
