Multiple sclerosis (MS) is a degenerative disease that affects the central nervous system. When a person has MS, their immune system attacks the protective covering of their nerves, damaging the avenues of communication between the brain and the body. Common symptoms of MS are vision problems, sensory loss, tingling, numbness, muscle spasms, tremors, lack of coordination, fatigue, dizziness, bladder and bowel dysfunction, and sexual dysfunction.

In some cases, testosterone-lowering medications may be considered for individuals who have committed sexual offenses in order to reduce their sex drive and the likelihood of them repeating the offense. Pharmacological interventions vary depending on the severity of the offense and the risk of reoffending, but some examples of medications used to reduce sex drive are selective serotonin reuptake inhibitors (SSRIs), cyproterone acetate (CPA), and gonadotropin-releasing-hormone (GnRH)-agonists. For very severe cases, GnRH-agonists may be used in combination with CPA.

Many women experience changes in their sexual function as they undergo menopause and the drop in estrogen that menopause causes. Estrogen is one of the main female sex hormones that supports vaginal lubrication and healthy vaginal tissues. As such, postmenopausal women may be more prone to vaginal dryness, decreased vaginal elasticity, vaginal itchiness, and discomfort or pain during sexual activity due to their decreased levels of estrogen.

Many experts acknowledge that sexual function is an important component of a person’s overall health and therefore something that should be assessed and treated by health care providers. Nevertheless, most medical definitions of sexual function and the validated tools used to measure sexual function remain very cisgendered and heteronormative (i.e., dealing only with cisgender heterosexual sex). This situation highlights a major gap in the evaluation and treatment of sexual dysfunction in transgender, non-binary, and other gender diverse individuals.
