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.
Additional recommended knowledge
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:
In females In males Description
Inferior rectal artery Inferior rectal artery to anal canal
Perineal artery Perineal artery supplies transversus perinei superficialis muscle
Posterior labial branches Posterior scrotal branches -
Artery of bulb of vestibule Artery of bulb of penis supplies bulbourethral gland
Dorsal artery of clitoris Dorsal artery of penis -
Deep artery of clitoris Deep artery of penis to corpus cavernosum penis
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.
