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:
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] [2]
In males, the internal pudendal artery also gives rise to the perforating arteries of the penis.
