Dorsal nerve of the penis
|Nerve: Dorsal nerve of the penis|
Pudendal nerve, its course through the lesser sciatic foramen, and branches, including dorsal nerve of the penis at bottom left.
Transverse section of the penis. (Dorsal nerve visible at top.)
|Latin||nervus dorsalis penis|
The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.
Piercing the inferior layer it gives a branch to the corpus cavernosum penis, and passes forward, in company with the dorsal artery of the penis, between the layers of the suspensory ligament, on to the dorsum of the penis, and ends on the glans penis.
It innervates the skin of the penis.
Dorsal Penile Nerve and Circumcision in Males
A recent clinical comparison evaluated post-surgical pain outcomes in boys receiving either pudendal nerve or dorsal penile nerve block after circumcision (the local anesthetic was a mixture of lidocaine, bupivacaine, fentanyl, and clonidine). Compared with pudendal nerve blockage, boys with dorsal penile nerve block had higher pain scores in the 48 hours postsurgery, and a higher proportion of patients with dorsal nerve blockage consumed post-surgical analgesics than patients with pudendal nerve blockage. The results support the notion that pudendal nerve blockage was more effective in treating post-circumcision pain than dorsal penile nerve blockage.
