Abstract
An orthodromic nerve conduction technique of the dorsal nerve of the penis was described in 27 normal men. The mean compound nerve action potential was 12.0 plus or minus 6.1 .mu.V. The nerve conduction velocity was 24.4 + 3.2 ms when the penis was at rest. Gentle stretch of the penis with a 1-lb weight increased the conduction velocity to 33.0 + 3.8 ms. Since the dorsal nerve of the penis has an important role in erection the new methodology may be useful in the evaluation of male impotence.
