Nerves of the male pelvis (English)

The lumbar, sacral and coccygeal plexuses give off several pelvic branches such as the obturator nerve, pudendal nerve, rectal nerves, scrotal nerves, and dorsal penis nerve. These nerves provide motor and sensory innervation to the muscles and skin of the pelvis. Lumbar and sacral splanchnic nerves provide the pelvis with autonomic innervation via the superior hypogastric plexus. This plexus gives off the left and right hypogastric nerves that merge with the pelvic splanchnic nerves to form the inferior hypogastric plexus. The superior and inferior hypogastric plexus further divide into smaller plexuses, forming the [ano]rectal plexuses, vesical plexus, deferential plexus, and prostate plexus. These subplexuses provide autonomic innervation to the male pelvic viscera and glands including the rectum, urinary bladder, testis, epididymidis, prostate and seminal glands.
