Electrical stimulation of the dorsal nerve of the penis elicited reflex tonic erections of the penile body and reflex bulbospongiosus muscle activity, flips and ejaculations. The tonic erections of the penile body are independent from contractions of the bulbospongiosus muscle and appear to be the result of a neurovascular process. Our observations suggest that reflex bulbospongiosus muscle activity, flips and ejaculations are a single complex reflex response, which we define as reflex ejaculatory response. Two parameters predicted the occurrence and type of reflex response. The visualization of bulbospongiosus muscle activity during surgical isolation of the dorsal nerve of the penis was sufficient to anticipate the elicitability of reflex ejaculatory responses. The latter, together with a systemic systolic pressure > 73mmHg., warranted the elicitability of reflex tonic erections. The similarities found in the physiology of rat tonic penile body erections and of human erections make this model promising for further elucidation of sexual function. Moreover, the present model may prove useful for the investigation of neurogenic erectile dysfunction, and of neurogenic ejaculatory disorders. © 1993 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited bySUGAYA K, OGAWA Y, HATANO T, KOYAMA Y, MIYAZATO T and ODA M (2018) EVIDENCE FOR INVOLVEMENT OF THE SUBCOERULEUS NUCLEUS AND NUCLEUS RAPHE MAGNUS IN URINE STORAGE AND PENILE ERECTION IN DECEREBRATE RATSJournal of Urology, VOL. 159, NO. 6, (2172-2176), Online publication date: 1-Jun-1998.
