Arteries of male pelvis (overview)

The arterial blood supply of the male pelvis is primarily derived from the common iliac arteries (Read more!), which arise from the bifurcation of the abdominal aorta at the level of the fourth lumbar vertebra (L4) and further divide into the internal iliac arteries and external iliac arteries at the level of the sacroiliac joints. These vessels, along with a few other contributors, ensure a rich and regionally specialized blood supply to the pelvic organs, musculoskeletal structures, and lower abdominal wall.

The internal iliac artery is the main source supplying arterial blood to the pelvic cavity. It enters the pelvis and further divides into anterior trunk and posterior trunk, which give rise to multiple visceral and parietal branches. These include arteries that supply the bladder, prostate, rectum, ductus deferens, penis, and perineum, as well as muscular and skeletal structures of the gluteal region.

Although primarily directed toward the lower limb, the external iliac artery also contributes to the pelvic region. Before passing beneath the inguinal ligament (Read more!) to become the femoral artery (Read more!) , it gives off the inferior epigastric artery and deep circumflex iliac artery (Read more!), which supply parts of the lower abdominal wall. In males, the inferior epigastric artery gives rise to the cremasteric artery, which enters the inguinal canal and supplies the coverings of the spermatic cord.

Overall, the arterial blood supply to the male pelvis is complex and highly organized, supporting a wide range of functions and ensuring adequate blood supply to pelvic organs, muscles, and urinary and reproductive structures. At the same time, pelvic arteries maintain vascular connection with the arteries of the abdomen and lower limb.
