MS and sexuality:
addressing a taboo subject with kindness
Understanding the sexual disorders related to multiple sclerosis, finding the words to talk about it, and discovering medical and relational solutions to maintain a fulfilling intimate life despite the disease
Sexuality is one of the aspects of life most profoundly affected by multiple sclerosis — and one of the least addressed in consultations. Neither patients often dare to talk about it, nor do caregivers always think to ask the question. As a result: the vast majority of sexual disorders related to MS remain unaddressed, while solutions exist. This guide addresses this topic with the kindness and rigor it deserves: understanding the neurological mechanisms that explain these disorders, knowing the available therapeutic options, finding the words to talk about it with your doctor and your partner, and discovering how MS can transform a couple's intimate life without necessarily destroying it.
1. Why does MS affect sexuality?
Multiple sclerosis can affect sexuality through three distinct interrelated and potentiating mechanisms — what specialists call the primary, secondary, and tertiary causes of sexual disorders in MS.
Primary causes
(direct neurological)
Direct lesions of the nerve pathways involved in the sexual response: spinal centers for erection and lubrication, genital sensory pathways, brain centers of desire.
Secondary causes
(symptoms of MS)
Debilitating fatigue, spasticity, pain, bladder disorders, cognitive disorders — all symptoms that indirectly disrupt sexual life without direct lesions of the genital pathways.
Tertiary causes
(psychological and relational)
Depression, anxiety, fear of partner judgment, changes in body image, changes in roles within the couple, fear of disease progression.
Iatrogenic causes
(effects of treatments)
Some treatments for MS or its symptoms (antidepressants, antiepileptics, beta-interferons) can have significant sexual side effects.
🧠 The taboo within the taboo: brain lesions and desire
In MS, lesions can affect the brain areas involved in sexual desire and emotional response to intimacy. A person may see their desire diminish or disappear without it being related to their feelings for their partner — it is a direct neurological consequence of the disease, not a signal about the relationship. Understanding and explaining this mechanism to their partner is often liberating for both members of the couple.
2. Specific sexual disorders: what women and men experience
Sexual disorders related to MS affect women and men differently, with specific manifestations that deserve to be known for better identification and treatment.
👩 In women with MS
Lubrication disorders: Vaginal dryness related to a disturbance of local autonomic innervation is common and can make intercourse painful. It is often effectively treated with suitable lubricants or local hormonal treatments. Orgasm disorders: Difficulties in reaching orgasm or changes in its quality and intensity are reported by many women with MS — related to lesions of the pelvic sensory pathways. Genital hypoesthesia: A decrease in sensitivity of the external genital organs, which can make stimulation insufficient or altered. Dyspareunia: Pain during intercourse, related to dryness, spasticity of the perineal muscles, or sensory disorders. Desire disorders: A decrease or absence of sexual desire, of neurological, hormonal origin, or related to fatigue and depression.
👨 In men with MS
Erectile dysfunction: Difficulty in obtaining or maintaining a satisfactory erection is the most frequently reported symptom, affecting 50 to 75% of men with MS at some point in their lives with the disease. It results from lesions of the spinal pathways controlling reflex and/or psychogenic erection. Ejaculatory disorders: Premature, delayed, absent, or retrograde ejaculation — ejaculatory disorders are common and can be very distressing for the man and his partner. Genital hypoesthesia: A decrease in sensitivity of the penis making stimulation insufficiently perceived to trigger a satisfactory erectile or ejaculatory response. Desire disorders: Decreased libido related to fatigue, depression, the effects of certain medications, or lesions of the brain circuits of desire.
💑 Common issues for both
Sexual fatigue: Sexual activity requires physical effort that fatigue MS can make difficult, even impossible at certain times. Perineal spasticity: Involuntary contractions of the perineal muscles can interfere with intercourse and cause discomfort or pain. Bladder issues during intercourse: The fear of urinary or fecal leaks is a major source of anxiety that can completely block sexuality. Hypersensitivity or pain: Some people experience painful hypersensitivity to touch in the genital areas. Heat-related fluctuations: The Uhthoff phenomenon (worsening of symptoms with body heat, especially during physical exertion) can temporarily amplify all sexual disorders.
3. The silence that costs: why this topic is not addressed
Despite their frequency and significant impact on quality of life, sexual disorders related to MS remain deeply underreported in medical consultations. Two-thirds of patients do not bring it up spontaneously — and half of caregivers do not ask the question. This double silence is maintained by well-identified barriers on both sides.
🤐 Patients' side: barriers to speaking out
- Shame and cultural taboo around sexuality
- Belief that the doctor is not the right person to talk to
- Fear of appearing superficial in light of the seriousness of the illness
- Lack of medical vocabulary to describe the disorders
- Feeling that nothing can be done
- Concern about hurting or worrying their partner
🩺 Caregivers' side: barriers to asking the question
- Lack of specific training on neurological sexual disorders
- Consultations too short to address this topic
- Fear of making the patient uncomfortable
- Prioritization of "more urgent" symptoms (motor, cognitive)
- Feeling that it is outside their area of expertise
- Stereotypical representations of the sexuality of chronic patients
“It took me three years to dare to talk about it to my neurologist. I thought it was a luxury complaint compared to my other symptoms. When I finally brought up the topic, she told me it was one of the disorders that impacted the quality of life of her patients the most and that a lot could be done. I should have spoken up much earlier.”

Talking about your sex life with your doctor is difficult — but it is possible, and it is necessary to access care. Here are some strategies to overcome this hurdle.
Prepare for the consultation
Write down what you want to say before the consultation. List the disorders you are experiencing, how long, how often, and what impact they have on your quality of life. Having written notes avoids memory blocks related to the stress of addressing a delicate topic and allows you to be precise even if emotion takes over.
Open the topic directly
A simple and direct sentence works better than circumlocutions: "I would like to talk to you about my sex life — MS has effects that I have never discussed with you." This wording clearly indicates the topic, anchors the issue in the disease (and not in your personal intimacy), and opens a legitimate medical discussion.
Use medical vocabulary
Using medical terms ("erectile dysfunction", "lubrication disorders", "difficulty reaching orgasm", "pain during intercourse") helps to objectify the subject and clearly place it in the medical register rather than personal. If you do not know the terms, simply describing what you feel is enough — the doctor will make the connection.
Request a specialized referral
If your general practitioner or neurologist does not feel comfortable with this topic, ask them to refer you to a sexologist, an andrologist (for men), a specialized gynecologist, or a physical medicine and rehabilitation (PMR) physician who will be trained in sexuality in neurological diseases. This referral is legitimate and normal.

The idea that "nothing can be done" is one of the most damaging myths regarding sexuality in MS. Many therapeutic options exist and can significantly improve sexual disorders — whether they are primary, secondary, or tertiary.
5.1 For erectile dysfunction
Phosphodiesterase type 5 (PDE5) inhibitors — sildenafil, tadalafil, vardenafil — are effective in the majority of men with MS experiencing erectile dysfunction. They do not restore desire (which depends on other mechanisms) but allow erection in the presence of sexual stimulation. Other options exist for refractory cases: intracavernous injections, vacuum devices, penile implants.
5.2 For lubrication and sensitivity disorders in women
Water-based or silicone-based lubricants (non-hormonal, easily available at pharmacies) can help compensate for vaginal dryness. Local hormonal treatments (vaginal estrogens) may be prescribed after hormonal assessment. Appropriate genital stimulation devices can help compensate for decreased sensitivity. Perineal physiotherapy exercises (with a physiotherapist specialized in perineology) effectively treat spasticity of the pelvic floor muscles.
5.3 For urinary disorders during intimacy
The fear of urinary leaks is one of the most significant barriers to sexuality in MS. Practical strategies can significantly reduce this risk: emptying the bladder immediately before intercourse, limiting drinks in the hours prior, choosing positions that exert less pressure on the bladder, using light protection for psychological safety. If urinary disorders are severe, a review of bladder treatment with the doctor can significantly improve the situation.
5.4 For fatigue and energy management
MS fatigue is one of the most common obstacles to a satisfying sex life. Some coping strategies: choose times of the day when energy is highest (often in the morning or early afternoon), plan intimate times rather than waiting for spontaneous impulse (which no longer comes), adapt positions to reduce physical effort, integrate rest periods before and after intimacy.
| Disorder | Main therapeutic options | Who to consult |
|---|---|---|
| Erectile dysfunction | PDE5 (sildenafil, tadalafil), injections, VAD | Neurologist / Andrologist |
| Vaginal dryness | Lubricants, local estrogens, vaginal moisturizers | Gynecologist / MPR |
| Perineal spasticity | Muscle relaxants, botulinum toxin, perineal physiotherapy | MPR Doctor / Physiotherapist |
| Desire disorders | Treatment of depression, sex therapy, hormone therapy | Sexologist / Psychiatrist |
| Orgasm disorders | Adaptation of stimulations, sex therapy, vibrostimulation | Sexologist / MPR |
| Genital pain | Neuropathic treatments, TENS, perineal physiotherapy | Neurologist / MPR / Physiotherapist |

Sexual disorders related to MS do not only affect the sick person — they transform the couple's intimate life. The partner may interpret disinterest or sexual difficulties as a sign of rejection, loss of love, or their own attractiveness. This misinterpretation, if not corrected, can create an emotional distance that further exacerbates the disorders.
6.1 Finding the words
The conversation about sexuality and MS is probably one of the most difficult for a couple. A few principles to approach it: choose a calm moment, outside the bedroom and away from a tension-filled episode related to sexuality. Talk about your feelings ("I feel...") rather than blaming or explaining. Clearly distinguish love and desire from physiological functioning ("It's not because I don't love you or I'm not attracted to you — it's my neurology that isn't cooperating like before"). Invite the partner to express what they are experiencing on their side.
💬 Approaching sexuality with your partner: concrete approaches
Choose the right moment
Outside the bedroom, away from tension, calm moment. Not just before or after intercourse. Not in the middle of fatigue or pain.
Talk about yourself first
Start by expressing what you are experiencing, without accusing or interpreting the partner. "I feel..." rather than "You are no longer..."
Invite to co-create
This is not a one-way problem. "What do you feel? How could we adapt things together?"
Reinvent intimacy
Sexuality can evolve, adapt, take new forms. The goal is not to "find" the past but to build a new possibility.
Consult together
Going together to the sexologist or MPR doctor transforms the issue from an individual problem to a couple challenge — which is what it really is.
Preserve tenderness
Non-sexual physical contacts (hugs, massages, hand in hand) maintain the emotional bond even when sexuality is suspended.

Access the training →7. The psychological dimension: depression, body image, and self-esteem
Sexual disorders in MS are deeply linked to the psychological health of the person. Depression — which affects 50% of MS patients during their lifetime — reduces desire, alters sexual response, and erodes motivation to maintain an intimate life. Changes in body image (visible fatigue, walking difficulties, spasticity, tremors) can profoundly affect self-esteem and confidence in one's own body as a desirable body.
Caring for one's psychological health is not an option in MS — it is a full medical component of care. An appropriate antidepressant treatment, psychological follow-up, or couple's therapy can radically transform the intimate life of a person with MS, regardless of medical solutions for physical disorders.

MS can erode motivation for all activities of life, including activities that maintain emotional bonds and self-esteem (outings, shared leisure, physical activity). The motivation chart helps identify and plan activities that maintain well-being and relational energy — an indirect but powerful pillar of intimate life.

Cognitive disorders related to MS (slowed processing, concentration difficulties, working memory) can affect the quality of relational interactions and, by extension, intimate life. A person whose cognitive abilities are better preserved communicates better with their partner, more easily maintains a strong emotional bond, and benefits from better overall well-being that supports sexual life.
Regular cognitive stimulation — via the CLINT app from DYNSEO for adults, specifically tailored to the cognitive profiles common in MS — indirectly contributes to maintaining a quality relational and intimate life. The DYNSEO cognitive tests allow tracking the evolution of cognitive functions and informing the care team to adapt the management.

For health professionals who support patients with MS, addressing sexuality in consultation is both a professional responsibility and a relational challenge. Here are the approaches recommended by the learned societies of neurology and sexology.
- Systematically ask the question — "How has your intimate life been since the onset of the disease?" integrated into the standard anamnesis, just like fatigue or walking
- Use a standardized questionnaire — such as the MSISQ-19 (Multiple Sclerosis Intimacy and Sexuality Questionnaire) to objectify the disorders without requiring direct oral conversation
- Normalize the subject — "Many of my patients with MS talk to me about changes in their intimate life — do you have anything to share about this?"
- Do not minimize — Avoid saying "It's normal with the disease" without offering support. Sexual disorders deserve as much attention as motor disorders
- Refer to the right specialists — Sexologist, rehabilitation physician, specialized gynecologist, andrologist, perineal physiotherapist depending on the nature of the disorders
- Involve the partner — Offer a couple's consultation with a sexologist or specialized psychologist when the relationship is impacted

Access the training →10. Reinventing intimacy: beyond genital sexuality
MS sometimes invites us to broaden the conception of sexuality beyond the genital-centered sexual act. This broadening is not a consolation or resignation — it is often a discovery that enriches intimate life far beyond what it was before the disease.
Sensual massages, shared body care, non-sexual physical tenderness, non-coital erotic games, erotic communication, exploration of new forms of stimulation — all dimensions of intimacy that can be maintained, even intensified, regardless of the physical limitations imposed by MS. This reinvention of intimacy generally requires talking, negotiating, and creating together — which can paradoxically deepen a couple's complicity beyond what it was.

The partner of a person with MS also experiences profound transformations in their intimate life. They may feel rejected, guilty about their own desires, exhausted by the accumulation of the caregiver role and the partner role, or deeply alone in their questions. These feelings are legitimate and deserve to be taken into account.
The caregiver has the right to express their own emotional and intimate needs in mutual respect. They have the right to seek individual psychological support to navigate this evolution. And they have the right to refuse to be defined solely by their caregiver role — including in the intimate relationship. The quality of the couple's life with MS largely depends on both partners' ability to mutually grant this right to their own existence.

Sexual disorders related to MS affect the vast majority of patients and have a profound impact on quality of life and couple life. They are traceable, manageable, and often improvable through a combination of medical, psychological, and relational solutions. The first step is to break the silence — with your doctor, with your partner, with yourself.

Q1 Do sexual disorders necessarily occur with MS?
No — sexual disorders are not inevitable and their severity varies considerably from one patient to another. They depend on the location of the lesions, the form of the disease, and associated symptoms. Some patients experience little or no sexual disorders, even after several years of illness. Others are affected from the early stages. Regular monitoring and open dialogue with one's doctor can help detect and treat these disorders as early as possible.
Q2 Do MS disease-modifying treatments have effects on sexuality?
Some treatments can have sexual side effects. Beta-interferons can sometimes induce fatigue and flu-like syndrome that indirectly reduce desire. Some symptomatic treatments (antispasmodics, antidepressants, antiepileptics used for neuropathic pain) have documented sexual effects. If you suspect that your treatment is affecting your sexuality, do not stop the treatment but discuss it with your neurologist — therapeutic alternatives can often be found.
Q3 Can sexuality trigger or worsen an MS relapse?
No — sexual activity does not trigger or worsen MS relapses. However, Uhthoff's phenomenon (temporary worsening of symptoms with an increase in body temperature related to exertion) can cause a temporary worsening of symptoms during and just after intercourse. This worsening is transient and disappears with cooling — it does not correspond to a relapse and does not require any specific treatment.
Q4 Are there resources or support groups for couples living with MS?
Yes — several resources exist in France: the French League Against Multiple Sclerosis (LFSEP) offers support groups and information on living with MS. The CRFSEP (Reference Centers for Multiple Sclerosis) provide multidisciplinary follow-ups sometimes including sexologists. Patient associations offer forums and exchange groups. Sexologists specialized in chronic illnesses work privately. Teleconsultation with a sexologist is possible and reimbursed under certain conditions since 2022.
