PURPOSE: We evaluated whether disrupting genital central nervous system pathways is associated with subjective reports of sexual dysfunction in women with multiple sclerosis. MATERIALS AND METHODS: We performed pudendal somatosensory evoked potential testing in and had sexual questionnaires completed by 14 women with a mean age of 47 years who had multiple sclerosis. RESULTS: The mean expanded disability status score was 5. All but 1 woman reported the desire for sexual intercourse. There was a high rate of dissatisfaction with their sex life and all study participants had concomitant bladder and bowel function problems. The most common sexual complaint was difficult or no orgasm, which was statistically associated with abnormalities or absence of 1 or both pudendal cortical evoked potentials. Fatigue and arousal disorders were also common. CONCLUSIONS: Women with multiple sclerosis have a high self-reported rate of sexual dysfunction, which decreases quality of life. Electrodiagnostic data imply that pudendal somatosensory innervation is necessary for normal female orgasmic function. More study is needed to confirm these findings.
