The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection. They arise from cell bodies in the inferior hypogastric plexus where they receive the pre-ganglionic pelvic splanchnic nerves (S2-S4).

There are both lesser cavernous nerves and a greater cavernous nerve.

Clinical considerations

These nerves are susceptible to injury following prostatectomy.

Nerve-Sparing prostatectomy was invented for surgeons to avoid injuring the nerves and causing erectile dysfunction complications. During surgery, a doctor may apply a small electrical stimulation to the nerve and measure the erectile function with a penile plethysmograph. [Dr. Peter Scardino's Prostate Book, Avery, 2005 ] This test aids the surgeon in identifying the difficult to see nerves. [Blue Torch [http://www.bluetorchmed.com] December 2007]
