Path

It then curves around the sacrospinous ligament to enter the perineum through the lesser sciatic foramen.

It travels through the pudendal canal with the internal pudendal veins and the pudendal nerve.

Branches

The internal pudendal artery gives off the following branches:

Some sources consider the urethral artery a direct branch of the internal pudendal artery^[1], while others consider it a branch of the perineal artery.^[2]

In males, the internal pudendal artery also gives rise to the perforating arteries of the penis.
