[Ejaculation disorders in multiple sclerosis: Prospective study of 44 patients]

To analyze in a descriptive way the ejaculation disorders during MS and to study the correlations between dysejaculations, other sexual, urinary and anorectal disorders.

Prospective, monocentric, non-interventional study. Ejaculation disorders were assessed by Premature Ejaculation Profile (PEP) scores, intravaginal latency, and the Male Sexual Health Questionnaire - Ejaculation (MSHQ-Ej). The sexual disorders were evaluated by the International Index of Erectile Function (IIEF15) and the Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ).

Forty-four men of mean age 46.8 (±10.3) years, with an average EDSS of 5.0 (±1.5) were included. According to the MSHQ-Ej score, ejaculation disorders were present in 28 out of 44 patients included (64%); 26/44 (59%) had an orgasm disorder, 23/44 (52%) a delay in ejaculation, 26/44 (59%) a decrease in ejaculation flow, 24/44 (55%) decreased ejaculated volume, 18/44 (41%) decreased ejaculation frequency, 15/44 (33%) ejaculatory pain and 11 34 (25%) showed systematic non ejaculation. The PEP score showed premature ejaculation in 14 patients (32%). The intra-vaginal latency time was less than 1minute in 6 patients (13.6%). There was a statistically significant correlation between ejaculation disorders and erectile dysfunction (P<0.05, correlation coefficient at 0.53) but no statistically significant correlation between ejaculation disorders and urinary or ano-rectal disorders.

Dysejaculation was present in 64% of MS. These disorders were mainly characterized by a decrease in the volume of the ejaculation, the strength of ejaculation and the delay in ejaculation.
