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.
