Sexual Dysfunction in MS
A 37-year-old woman presents to her primary care clinic with a chief complaint of depression. She was diagnosed with relapsing multiple sclerosis (MS) at age 29 and is currently taking an injectable preventive therapy. Over the past 6 months, she has had increased marital strain secondary to losing her job because “I couldn’t mentally keep up with the work anymore.” This has caused financial difficulties for her family. In addition, she tires easily and has been napping in the afternoon. She and her husband are experiencing intimacy difficulties, and she confirms problems with vaginal dryness and a general loss of her sexual drive.
Sexual dysfunction in MS is common, affecting 40% to 80% of women and 50% to 90% of men with MS. It is an “invisible” symptom, similar to fatigue, cognitive dysfunction, and pain.1-3
There are three ways that MS patients can be affected by sexual dysfunction, and they are categorized as primary, secondary, and tertiary. Primary sexual dysfunction results from demyelination/axonal destruction of the central nervous system, which potentially leads to altered genital sensation or paresthesia. Secondary sexual dysfunction stems from nonsexual MS symptoms, such as fatigue, spasticity, tremor, impairments in concentration/attention, and iatrogenic causes (eg, adverse effects of medication). Tertiary sexual dysfunction involves the psychosocial/cultural aspects of the disease that can impact a patient’s sexual drive.
SYMPTOMS
Like many other symptoms associated with MS, the symptoms of sexual dysfunction are highly variable. In women, the most common complaints are fatigue, decrease in genital sensation (27%-47%), decrease in libido (31%-74%) and vaginal lubrication (36%-48%), and difficulty with orgasm.4 In men with MS, in addition to erectile problems, surveys have identified decreased genital sensation, fatigue (75%), difficulty with ejaculation (18%-50%), decreased interest or arousal (39%), and anorgasmia (37%) as fairly common complaints.2
TREATMENT
Managing sexual dysfunction in a patient with MS is dependent on the underlying problem. Some examples include
- For many patients, their disease causes significant anxiety and worry about current and potentially future disability—which can make intimacy more difficult. Sometimes, referral to a mental health professional may be required to help the patient
with individual and/or couples counseling to further elucidate underlying intimacy issues. - For patients experiencing MS-associated fatigue, suggest planning for sexual activity in the morning, since fatigue is known to worsen throughout the day.
- For those who qualify for antidepressant medications, remember that some (eg, selective serotonin reuptake inhibitors) can further decrease libido and therefore should be avoided if possible.
- For women who have difficulty with lubrication, a nonpetroleum-based lubricant may reduce vaginal dryness, while use of a vibrator may assist with genital stimulation.
- For men who cannot maintain erection, phosphodiesterase inhibitor drugs (eg, sildenafil) can be helpful; other options include alprostadil urethral suppositories and intracavernous injections.
The patient is screened for depression using the Patient Health Questionnaire, which yields a score of 17 (moderately severe). You discuss the need for active treatment with her, and she agrees to start an antidepressant medication. Bupropion is chosen, given its effectiveness and lack of adverse effects (including sexual dysfunction). The patient also is encouraged to use nonpetroleum-based lubricants. Finally, a referral is made for couples counseling, and a 6-week follow-up appointment is scheduled.
CONCLUSION
Sexual dysfunction in MS is quite common in both women and men, and the related symptoms are often multifactorial. Strategies to address sexual dysfunction in MS require a tailored approach. Fortunately, any treatments for sexual dysfunction initiated by the patient’s primary care provider will not have an adverse effect on the patient’s outcome with MS. For more complicated cases of MS-associated sexual dysfunction, urology referral is recommended.
