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:
{| class="wikitable"
| '''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<ref>{{Dorlands|a_61|12156483}}</ref>, while others consider it a branch of the [[perineal artery]].<ref>{{eMedicineDictionary|Urethral+artery}}</ref>
In males, the internal pudendal artery also gives rise to the perforating arteries of the penis.
