[Lesion of the dorsal nerve of the penis in Peyronie's disease].

Twelve patients with La Peyronie disease underwent complete neurophysiological investigation of the perineum including evaluation of the nerve conduction velocity of the dorsal nerve of the penis. A significant reduction was observed in this velocity with a reduction in the amplitude of the sensory potential in patients with associated disorders of erection or sensory disturbances (paraestesiae of the glans). A compressive lesion of the dorsal nerve by hard nodules buried in the dermis of the dorsal surface of the penis was suspected.
