A prolonged bulbocavernosus reflex latency (that is more than 45 msec.) or the absence of a reflex response of the bulbocavernosus muscles during electrical stimulation of the glans penis is considered a sign of neurological disease. Since only a few experimental studies have been performed in man related to the neurophysiological mechanism of erection, and since the results of these studies were contradictory the diagnostic validity of bulbocavernosus reflex measurement was reassessed. We determine whether men with abnormal bulbocavernosus reflex latencies have concomitant organic erectile dysfunction as confirmed by nocturnal plethysmographic and rigidity recordings. The bulbocavernosus reflex was recorded in 90 subjects and 19 had abnormal bulbocavernosus reflex latencies. Of these 19 subjects 8 had normal nocturnal erections, thus, confirming a diagnosis of psychogenic impotence. These results cast some doubts on the validity of bulbocavernosus reflex measurement for the diagnosis of organic erectile dysfunction due to a neurological disease. © 1989 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited byYILMAZ U, SOYLU A, ÖZCAN C, KUTLU R and GÜNEŞ A (2018) EVOKED CAVERNOUS ACTIVITYJournal of Urology, VOL. 167, NO. 1, (188-191), Online publication date: 1-Jan-2002.Fabra M, Frieling A, Porst H and Schneider E (2018) Single Potential Analysis of Corpus Cavernosum Electromyography for the Assessment of Erectile Dysfunction: Provocation, Reproducibility and Age Dependence-Findings in 36 Healthy Volunteers and 324 PatientsJournal of Urology, VOL. 158, NO. 2, (444-450), Online publication date: 1-Aug-1997.Stief C, Thon W, Djamilian M, Allhoff E and Jonas U (2018) Transcutaneous Registration of Cavernous Smooth Muscle Electrical Activity: Noninvasive Diagnosis of Neurogenic Autonomic ImpotenceJournal of Urology, VOL. 147, NO. 1, (47-50), Online publication date: 1-Jan-1992.Bemelmans B, Van Kerrebroeck P, Notermans S, Wijkstra H and Debruyne F (2018) Motor Evoked Potentials from the Bladder on Magnetic Stimulation of the Cauda Equina: A New Technique for Investigation of Autonomic Bladder InnervationJournal of Urology, VOL. 147, NO. 3 Part 1, (658-661), Online publication date: 1-Mar-1992.Stief C, Djamilian M, Anton P, de Riese W, Allhoff E and Jonas U (2018) Single Potential Analysis of Cavernous Electrical Activity in Impotent Patients: A Possible Diagnostic Method for Autonomic Cavernous Dysfunction and Cavernous Smooth Muscle DegenerationJournal of Urology, VOL. 146, NO. 3, (771-776), Online publication date: 1-Sep-1991.Bemelmans B, Meuleman E, Anten B, Doesburg W, Van Kerrebroeck P and Debruyne F (2018) Penile Sensory Disorders in Erectile Dysfunction: Results of a Comprehensive Neuro-Urophysiological Diagnostic Evaluation in 123 PatientsJournal of Urology, VOL. 146, NO. 3, (777-782), Online publication date: 1-Sep-1991.
