Sexual dysfunction in female patients with relapsing-remitting multiple sclerosis.

INTRODUCTION: Sexual dysfunction (SD) is one of the common symptoms of multiple sclerosis (MS) and is often underdiagnosed, especially in women. Relapsing-remitting multiple sclerosis (RRMS) is the most widespread form of the disease, but the data on SD occurrence in this particular group of patients is limited. The aim of the study was to analyze the associations between demographic factors, symptoms and signs of MS, psychiatric comorbidities and SD in female patients with RRMS.

MATERIAL & METHODS: A subgroup of 86 sexually active women with RRMS out of 218 total MS respondents was analyzed. Exclusion criteria included active relapse, EDSS score equal or higher than 6.5, and current pregnancy. All patients completed questionnaires including demographic data, questions about symptoms and signs of MS, Female Sexual Function Index (FSFI) for sexual performance, Patient Health Questionnaire 9 (PHQ-9) for depression, and Fatigue Severity Scale (FSS) for fatigue evaluation.

RESULTS: According to FSFI, SD occurred in 21 (27.27%) of the respondents. SD occurrence was associated with depression ( p  < .05) and speech disturbances ( p  < .04). A negative effect on sexual performance was associated with depression intensity ( p  < .003), fatigue intensity ( p  < .05), more advanced age at diagnosis ( p  < .02), lower education level ( p  < .05), and smaller area of residence ( p  < .002).

CONCLUSIONS: SD in women with RRMS is mostly associated with psychosocial parameters. Patients who are more depressed, presenting speech problems, less educated, and from smaller towns, should be considered high-risk for sexual dysfunction.
