Abstract
Diagnostic tools of impotence are the matter of interest of many investigators. Recent publications cast some doubts about the relevance of sacral latency for diagnosing especially autonomic fraction of the neurogenic impotence. Our aim of this study was to evaluate the new test probably specific for discovering the autonomic impotence, the so called Single Potential Analysis of the Cavernous Electric Activity (SPACE). The procedure is minimally invasive, reproducible and easy to perform, where recording of the potentials during flaccidity and after sexual stimulation (injection of papaverine + manual self stimulation), are quite diagnostic for the increased duration and amplitude of the potentials in contrast to the normal behavior of the muscle in the normal subjects. On that previous fact the diagnosis in built, where it reveals the dramatic decrease in the tone controlling the smooth muscle contraction; the sympathetic tone, that produces non-synchronization of the smooth muscle cells. Sacral latency has many advances but$ is of less or no value in diagnosing the impotence due to autonomic neuropathy, which is efficiently discovered by SPACE.
