[The bulbocavernosus reflex in controls and patients with potency disorders].

The bulbocavernosusreflex (BCR) was examined in 34 controls and in 98 patients with disturbances of potency. The shortest and longest latencies, the mean and the temporal dispersion out of ten successive reflex responses were measured. Additionally the smallest and largest side differences were determined when recording reflex responses simultaneously from the right and left bulbocavernosus muscles. BCR measurements revealed pathological results in 57 patients. Most sensitive parameters were the temporal dispersion and maximum side difference.
