Sexual dysfunction is an under-recognised epilepsy comorbidity. In women it can affect desire, arousal, lubrication, orgasm, satisfaction and pain, and the causes can include epilepsy itself, medication, reproductive hormones, mood, relationship factors and fear of seizures.
It is more common than routine clinic discussion suggests
A 2026 scoping review found that sexual problems are common in people with epilepsy but remain poorly assessed and under-treated.
Reported prevalence varies widely because studies use different populations, definitions and questionnaires.
There is rarely one cause
Seizure burden, depression, anxiety, stigma, relationship stress, endocrine dysfunction and medication can all contribute.
That means a sexual problem should not automatically be attributed to epilepsy itself.
Hormones and antiseizure medicines may contribute
Enzyme-inducing antiseizure medicines can alter circulating sex hormones and binding proteins.
Other medicines—including some psychiatric treatments commonly used alongside epilepsy care—can affect libido, arousal or orgasm.
Fear of seizures during sex is a real issue
Some people avoid sexual activity because they fear having a seizure during intimacy or worry about a partner’s reaction.
Education about the person’s actual seizure risk and communication within the relationship can be as important as medication changes.
Sexual symptoms can be a quality-of-life signal
Reduced desire or arousal may coexist with fatigue, endocrine disturbance, mood disorder, pain or medication toxicity.
Addressing the symptom can therefore uncover other treatable health problems.
Treatment evidence in epilepsy is limited
The 2026 review found that although treatments for sexual dysfunction exist, epilepsy-specific evidence for management is limited.
Assessment should therefore focus on reversible contributors, medication review, endocrine or gynaecological issues, psychological health and appropriate specialist referral.
Clinicians need to ask
Sexual health is often omitted from epilepsy consultations unless the patient raises it first.
Normalising the question can reduce embarrassment and help identify a substantial but hidden part of epilepsy-related quality of life.
