Cavernous nerves of penis
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). Additional recommended knowledgeThere are both lesser cavernous nerves and a greater cavernous nerve. Clinical considerationsThese nerves are susceptible to injury following prostatectomy. Nerve-sparing prostatectomy was invented for surgeons to avoid injuring the nerves an causing erectile dysfunction complications. During surgery, a doctor may apply a small electrical stimulation to the nerve and measure the erectile function.[1] This test aid the surgeon in identifying the difficult to see nerves.[2] ReferencesGray's Anatomy, 1918 edition
