Sexual Motivation in Persons with Multiple Sclerosis: A Controlled Cross-Sectional Study

Area of Science:

• Neuroscience
• Psychology
• Sexual Health

Background:

• Sexual motives significantly influence sexual behavior.
• Multiple Sclerosis (MS) is a chronic neurological condition impacting physical and emotional well-being, often affecting sexual function.
• Understanding sexual motives in MS is crucial for addressing sexual health concerns.

Purpose of the Study:

• To investigate and compare sexual motives between individuals with multiple sclerosis (MS) and a matched control group.
• To identify specific factors and sub-factors of sexual motivation that differ between persons with MS and controls.

Main Methods:

• A cross-sectional study involving 157 persons with MS and 157 propensity score-matched controls.
• The Reasons for Having Sex (YSEX) questionnaire was used to assess 140 distinct sexual motives.
• Statistical analysis included calculating mean differences in primary and sub-factor scores, sexual satisfaction, and importance of sex.

Main Results:

• Persons with MS reported lower engagement in sex for Physical, Emotional, and Insecurity motives compared to controls.
• Specific physical motives (Pleasure, Experience seeking) and emotional motives (Love and commitment) were significantly reduced in the MS group.
• The overall importance of sex was lower in individuals with MS.

Conclusions:

• Multiple sclerosis is associated with a reduction in the diversity and frequency of sexual motives, particularly those related to physical pleasure and experience seeking.
• Healthcare professionals should consider evaluating sexual motivation in individuals with MS presenting with decreased sexual desire or other sexual dysfunctions.
• These findings highlight the importance of addressing sexual health in the comprehensive management of multiple sclerosis.
