Sexual dysfunction in women with multiple sclerosis: prevalence and impact on quality of life

Background Sexual function is a component of quality of life, and sexual dysfunction entails reduced satisfaction with life and impaired mood and quality of relationships and affects not only the individual's quality of life, but her partner's life as well. Since Sexual Dysfunction (SD) is among the most common complaints of patients with Multiple Sclerosis (MS), this study was conducted to determine the prevalence of SD among women with MS and its effect on quality of life. Materials and methods This cross-sectional study was conducted in 2018 on 300 women with MS aged 22-50 years in Isfahan, Iran, selected through systematic random sampling. Data were collected using the standard Female Sexual Function Index (FSFI) and MSQOL-54 and analyzed in SPSS using descriptive and analytical statistics. Results The overall prevalence of SD was found as 69.8% in women with MS, with the dimension of sexual desire being affected in 38.6% of the cases, sexual arousal in 38.6%, lubrication in 23.7%, orgasm in 37.3%, satisfaction in 23.4% and pain in 16.9%. SD was found to have significant relationships with age, duration of marriage, fatigue, EDSS and the combined physical and mental health aspects of quality of life (P < 0.05). Moreover, logistic regression analysis revealed that there was a higher probability of a sexual dysfunction among patients with MS and a high fatigue score [1.228(1.003 to 1.504); P = 0.047]. The mean score of the combined physical and mental health aspects of quality of life was lower in the group of women with MS and SD compared to those without SD, and the difference between the two groups was statistically significant (P < 0.05). Conclusion Sexual dysfunction is highly prevalent among women with MS and affects various dimensions of quality of life. Greater attention should be paid to the sexual problems faced by MS patients in order to improve their quality of life.
