摘　　要：Aim: Extensive neurophysiological investigations were carried out in 100 healthy subjects and 84 patients with penileerectile dysfunction. Methods: Following examinations were performed, spinal and scalp somatosensory evoked poten-tials (SEPs) to stimulation of the dorsal nerve of penis, motor evoked potentials (MEPs) from bulbocavernosus (BC) inresponse to scalp and spinal root stimulation, and measurement of sacral reflex latency (SRL) from anal sphincter (AS).Results: In the healthy subjects, the mean sensory total conduction time (sensory TCT), as measured at the peak of thescalp P1 (P40) wave was 39.73 ms. The mean sensory central conduction time (sensory CCT = spinal-to-scalp conductiontime) was 28.98 ms. The mean peripheral conduction time (PCP) was 9.40 ins. Transcranial brain stimulation was per-formed by using a magnetic stimulator during voluntary contraction of the examined muscle. Spinal root stimulation wasperformed at rest. Motor total conduction time (motor TCT) to BC muscles was 20.48 ms. Motor central conductiontime (motor CCT) to sacral cord segments controlling BC muscles was 14.42 ms at rest. The mean SRL was 35.13 ms.Conclusion: Combined or isolated abnormalities of SEPs, MEPs, and SRL were found in patients with erectile dysfunc-tion.
