A review of the electromyographic criteria in sexual performance.

Given that the criteria for sexual performance including males considered normal is not clear in available literature, the authors sought a way to choose standards that would leave no doubts as far competence of performance and neurophysiological integrity in the control of sexual performance. The results found in more than 5,000 electromyographic evaluations on erectile dysfunction were equivalent to the results from a previous research, "The electromyographic gold standard to male sexual capacity", where normal males were evaluated according to the latency period, amplitude and morphology. To classify the results as "The gold standard", we used a selected and accurate method that excluded any doubts about the sexual performance. These men had the installation capacity, maintenance and control of their ejaculation, totally voluntary. The similarity between the clinical picture and the electromyographic events, suggests that the amplitude and the morphology, beyond the latency period, may indicate the quality of neurotransmission.
