External pudendal artery

The external pudendal artery and its branches.

The External pudendal artery is a small artery in the pelvis that supplies blood to the skin and muscles in the perineum and genitalia. It is a branch of the femoral artery, which is the main artery of the lower limb.

Structure

The external pudendal artery originates from the femoral artery in the upper part of the femoral triangle. It then passes medially and downwards to reach the perineum and genitalia. It gives off several branches, including the inferior labial artery and perineal artery.

Function

The external pudendal artery supplies blood to the skin and muscles of the perineum and genitalia. It also contributes to the blood supply of the scrotum in males and the labia in females.

Clinical significance

Knowledge of the external pudendal artery is important in surgical procedures involving the perineum and genitalia. Damage to this artery can lead to ischemia and tissue necrosis.
