Dorsal nerve of the penis nerve conduction velocity: a new technique.
In the evaluation of a possible peripheral neuropathic process as the etiology of erectile dysfunction, studies of the dorsal nerve of the penis may be unique in that they allow examination of the most distal segment of pudendal nerve in isolation. This study describes a new technique using a simple traction device for elongation of the penis to determine the orthodromic nerve conduction of the dorsal nerve of the penis. With stimulation at the glans, and recording at the base of the penis, the value obtained in 20 normal subjects was 36.2 +/- 3.2 m/s with an amplitude of 2.29 +/- 1.08 mV.
