Overview
Sexual problems are often experienced by people with MS, but they are very common in the general population as well. Sexual arousal begins in the central nervous system, as the brain sends messages to the sexual organs along nerves running through the spinal cord. If MS damages these nerve pathways, sexual response — including arousal and orgasm — can be directly affected. Sexual problems also stem from MS symptoms such as fatigue or spasticity, as well as from psychological factors relating to self-esteem and mood changes.
Treating Sexual Problems
Both men and women with MS may experience difficulty achieving orgasm or loss of libido. They and their partners can benefit from instruction in alternative means of sexual stimulation, such as the use of a vibrator, to overcome slow arousal and impaired sensation. Abnormal sensations and spasms can often be controlled through use of medication. Techniques such as intermittent catheterization or medication can control urinary leakage during intercourse.
