Sexual function in multiple sclerosis. A 5-year follow-up study

Sexual dysfunction is known to occur in multiple sclerosis (MS). The purpose of the study is to describe the change in sexual function and symptoms in a longitudinal study. Forty-nine patients (27 females, 22 males) with definite MS were interviewed and examined with 5 years interval. The number of patients with sexual dysfunction increased significantly (p = 0.009) and involved females and males equally. Males usually had I or two symptoms of sexual dysfunction, while females frequently had 2 or more symptoms. It is concluded that the risk of sexual dysfunction increases over time. Further studies in treatment possibilities are needed.
