[Penile neuropathy: clinical and electrophysiologic study. Report of 186 cases]

Penile neuropathy is a common disease due to lesion of the sensory branch of the pudendal nerve, ie, the dorsal nerve of the penis. Sexual disorders (deterioration of erection) and sensory signs (hypoesthesia or paresthesia of the penis) are noted in patients with penile neuropathy. Electrophysiological recordings help guide the diagnosis (reduction of the sensory velocity of the dorsal nerve of the penis). Many etiologies can be found (traumatic, toxic, compressive), but the most common lesion is neuropathy related to diabetes.
