The internal pudendal artery is an artery that branches off the internal iliac artery, providing blood to the external genitalia.
The internal pudendal artery is the terminal branch of the anterior trunk of the internal iliac artery. It is smaller in the female than in the male.
Path
It exits the pelvic cavity through the greater sciatic foramen to enter the gluteal region.
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.
