[Neurophysiologic evaluation of erectile dysfunction]

The bulbocavernosus reflex and pudendal evoked responses were obtained in a group of 12 healthy male subjects and in 38 impotent men. The dorsal nerve of the penis was stimulated electrically. Responses were recorded over the bulbocavernosus muscle by a percutaneous method and over the cerebral cortex from the Cz-2 point.
