Abstract :Objective: In this study, the bulbocavernosus reflex insert ignore into journalissuearticles values(BCR);, pudendal evoked potentials insert ignore into journalissuearticles values(PEP`s); and tibial evoked potentials insert ignore into journalissuearticles values(TEP`s); in 10 cases with the diagnosis of definite Multiple Sclerosis insert ignore into journalissuearticles values(MS);, between the ages of 21-58 insert ignore into journalissuearticles values(Mean Age: 32.2); were investigated. In 8 of the 10 cases, an erectile impotence complaint was present. Methods: In order to exclude clinical pictures that can cause impotence, detailed neurological and urological examinations were made in all the subjects. In all the patients, bulbocavernosus reflexes insert ignore into journalissuearticles values(obtained by stimulating the penis dorsal nerve and recording with a needle electrode from the bulbocavernosus muscle);, pudendal evoked potentials insert ignore into journalissuearticles values(obtained by stimulating the penis dorsal nerve and recording from the scalp); and tibial somatosensory evoked potential insert ignore into journalissuearticles values(obtained by stimulating the posterior tibial nerve and recording from the scalp); were investigated. The results were compared with the normal values of Department of Neurophysiology Laboratory, and the values higher than the upper limit of the normal value insert ignore into journalissuearticles values(mean+2SD); were accepted as abnormal. Results: TEP`s and the PEP`s were found to be abnormal in all patients in the study insert ignore into journalissuearticles values(100%);; while the BCR’s in three patients with erectile impotence were abnormal. In the remaining 5 patients with impotence and the two patients without impotence complaints, the BCR latencies were found to be normal. Conclusion: It was concluded that in the neurophysiological assessment of impotence in MS to aid the diagnosis, the BCR investigation is net a valuable method.
