Dorsal nerve of the penis is the deepest division of the pudendal nerve that passes through the deep perineal pouch and supplies the skin of the penis.
Dorsal nerve of the penis accompanies the internal pudendal artery and runs forward along the margin of the inferior ramus of pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.
As described above, the dorsal nerve of penis supplies the skin of penis. It pierces the inferior layer of the urogenital diaphragm and gives a branch to the corpus cavernosum of penis. It then passes forward, accompanying the dorsal artery of penis on to the dorsum of the penis. It ends on the glans penis.
