[Neurophysiological studies in 200 impotent men: the value of the bulbocavernous reflex and of penile evoked potentials].

After having investigated 200 males with impotence, the authors conclude that the study of the bulbocavernous reflex and the penile evoked potentials are of a certain importance when a neurological origin is suspected as the cause of the impotence. The usual urological investigations during the work-up of impotence should always be carried out in order to improve the insight into the relationships between the different examinations.
