Internal pudendal artery

  • The internal pudendal artery (latin: arteria pudenda interna) is a branch of the anterior division of the internal iliac artery.

    The internal pudendal artery leaves the pelvic cavity via the infrapiriform foramen, then it turns around the ischial spine and passes anteriorly along the lateral wall of the ischioanal fossa.

    The internal pudendal artery gives off the following branches:

    • inferior rectal artery,
    • perineal branches,
    • urethral artery,
    • penile bulb artery (for a male),
    • vestibular bulb artery (for a female).

    The internal pudendal artery supplies the lower part of the rectum, perineal muscles, urethra, scrotum and bulb of the penis (in males), labia majora and bulb of the vestibule (in females).
