[Electrophysiologic studies in the descending perineum in women].

Seventy five female patients (mean age: 55 +/- 13 years) were included into the study. Electromyography of the perineum with study of the intramuscular activity of the external anal sphincter was done and measures of the sacral reflex latency were obtained by stimulation of the cavernous nerve of the clitoris, recording in the external anal sphincter muscle. Neurogenic syndromes of pudendal nerve either isolated or associated with muscular disorders have been shown to be correlated with descending perineum. In our study, we investigated whether a history of obstetrical or surgical interventions is related to the occurrence of this syndrome. We did not find any significant relationship.
