Sexual health is one of the quieter casualties of how schizophrenia care is organised. Psychiatric appointments rarely include it; primary care visits for people with severe mental illness are often less frequent than they should be; and stigma — both internalised and external — keeps a lot of conversations from happening at all. The result is higher rates of unintended pregnancy, undiagnosed sexually transmitted infections, and intimate-partner difficulties than the general population. None of this needs to be the case.
People with schizophrenia have the same right to satisfying intimate lives, accurate sexual health information, and respectful contraception and STI care as anyone else — and they often need clinicians to bring it up first.
The honest data picture
A 2018 systematic review in Schizophrenia Bulletin (Hughes et al.) reported elevated rates of HIV, hepatitis B, hepatitis C, and other STIs in people with severe mental illness compared with the general population. Risk factors include lower rates of consistent condom use, higher rates of injection drug use in some subgroups, and reduced access to consistent primary care. Importantly, sexual functioning itself — desire, arousal, orgasm — is also frequently affected by both the illness and its treatment.
What antipsychotics do to sexual function
Hyperprolactinaemia
Several antipsychotics — especially risperidone, paliperidone, and the older typicals (haloperidol, fluphenazine) — block dopamine in the pituitary, causing prolactin levels to rise. High prolactin causes:
- Reduced libido in all genders
- Erectile dysfunction
- Vaginal dryness
- Menstrual irregularities or absence (amenorrhoea)
- Sometimes nipple discharge (galactorrhoea), even in men
If you suspect prolactin issues, a simple blood test confirms it. See hyperprolactinaemia overview.
Sedation and motivation
Heavy sedation, blunted motivation (negative symptoms), and the combination of antipsychotics with antidepressants can all affect interest in sex.
Direct sexual dysfunction
Most antipsychotics can cause some degree of sexual dysfunction independent of prolactin — through anticholinergic effects, blood pressure changes, or central nervous system effects. The frequency varies by medication. See sexual side effects.
What can help
- Tell your prescriber. Sexual side effects are one of the most common reasons people quietly stop their medication. Most prescribers welcome the conversation and can often help.
- Switching antipsychotics — aripiprazole and brexpiprazole tend to lower prolactin; lurasidone, ziprasidone, and quetiapine are also relatively prolactin-sparing.
- Adjunctive aripiprazole — sometimes added at low dose to a prolactin-raising antipsychotic to bring prolactin down.
- Treating contributing conditions — depression, sleep problems, thyroid issues, low testosterone, diabetes-related vascular issues.
- PDE5 inhibitors (sildenafil, tadalafil) — prescribed for erectile dysfunction; effective in many men with antipsychotic-related ED.
- Lubricants and arousal time — practical, simple, often overlooked.
STI screening: what is recommended
The CDC STI screening recommendations apply to everyone, with some adjustments for people at higher risk:
- HIV — at least once for all adults aged 13–64; more often for people with risk factors
- Hepatitis C — at least once in adulthood; more often if injection drug use
- Hepatitis B — at least once in adulthood; vaccination is widely available
- Chlamydia and gonorrhoea — annually for sexually active people under 25 and those at higher risk
- Syphilis — annually for higher-risk populations
If you have not had these screenings, asking your primary care doctor or a sexual health clinic is an entirely normal request. CDC GetTested can find local testing sites.
Contraception
Contraception is a particularly important conversation for people of childbearing potential who take antipsychotics, for two reasons:
- Some antipsychotics (the prolactin-raising ones) can suppress ovulation enough to mask fertility issues but not reliably enough to prevent pregnancy. People sometimes assume they cannot get pregnant on these medications and find out otherwise.
- Some antipsychotics have specific risks in pregnancy that warrant planning, not surprises. Valproate, in particular, is contraindicated in pregnancy because of major birth defect risk.
Long-acting reversible contraception (LARC) — IUDs and implants — is highly effective, low-maintenance, and reduces the daily burden of remembering pills. Discuss options with a primary care doctor or gynaecologist. See schizophrenia and fertility and parenting while on antipsychotics.
You have unprotected sex and need emergency contraception (effective up to 5 days after, most effective in the first 72 hours), believe you have been exposed to HIV (post-exposure prophylaxis works best within 72 hours), or experience symptoms of an STI (genital sores, unusual discharge, pelvic pain, painful urination).
Intimacy, partners, and disclosure
Beyond labs and pills, intimacy itself is worth attention. People with schizophrenia date, marry, partner, and have rich romantic and sexual lives. Issues that come up include:
- How and when to disclose a diagnosis to a partner
- Managing intimacy during periods of higher symptoms
- Talking to partners about medication side effects on sex
- Concerns about heritability when planning a family — see genetic counselling
Couples therapy, peer support, and writing about intimacy by people with lived experience can all help. See dating with schizophrenia.
Trauma-informed sexual healthcare
Rates of sexual violence and trauma history are higher among people with severe mental illness. A trauma-informed approach to pelvic exams, STI testing, and sexual history-taking is the standard of care. You can ask for a chaperone, ask for a smaller speculum, ask to pause, or ask to defer parts of an exam. A clinician who reacts well to those requests is worth keeping.
The bottom line
Sexual health is health. The most useful single thing many people with schizophrenia can do is open one short conversation — with a primary care doctor, a sexual health clinic, or a trusted psychiatrist — about screening, contraception, or side effects. The information is usually reassuring, and the small problems caught early stay small.
