Peripheral nerve conduction studies and bulbocavernosus reflex in the investigation of impotence.

Abstract

Patients with erectile dysfunction underwent sensory and motor conduction and bulbocavernosus reflex tests to determine the incidence of peripheral nerve involvement. Of a total of 111 patients, abnormal sensory conduction was found in 87 (78%), abnormal motor conduction in 56 (50%), and abnormal bulbocavernosus reflex in 40 (36%). Most of these patients had other medical problems. Objective evidence of peripheral nerve involvement helped in the management of these patients.
