摘      要：Aim: Electrophysiological monitoring of the activity of the penile sympathetic skin responses (PSSR) in healthy menand patients with erectile dysfunction (ED). Methods: PSSR were recorded from the skin of penis with disk elec-trodes at the time of electric stimulation of left median nerves. Results: PSSR were recorded from all the healthymen and almost all the patients. In healthy men the latency of P_0, the latency of N_1, the duration of N_1 and the ampli-tude of N_1 were 1249 ± 111 ms, 2239 ± 286 ms, 1832 ± 505 ms and 470 μV (median), respectively. In ED patientsthe latency of P_0, the latency of N_1, the duration of N_1 and the amplitude of N_1 were 1467 ± 183 ms ( P 0.01), 2561± 453 ms (P 0.05), 2560 ± 861 ms (P 0.01 ) and 91 μV (P 0.01), respectively. The normal latency of Powas less than 1471 ms. The normal amplitude of N1 was more than 235μV. According to this normal value, of 20 pa-tients 11 showed longer latency of P_0, and 14 showed lower amplitude of N_1 as compared with those of normal ***: PSSR can be used as an electrophysiological method in assisting the diagnosis of ED.(Asian J Androl 2001; Mar; 3: 45-48)
