The myth: "People with schizophrenia shouldn't have children — they'll pass it on, and they can't be good parents anyway." This idea has appeared in everything from old textbooks to family arguments, and it carries echoes of explicit eugenics policies that targeted people with mental illness in the early 20th century.
Many people with schizophrenia raise children well; genetic risk to offspring is real but modest, and decisions about having children belong to the individual and their partner — not to outside judgement.
The historical context
This myth has uglier roots than most. In the early 20th century, dozens of US states had compulsory sterilisation laws, often targeting people with serious mental illness. Buck v. Bell (1927), the US Supreme Court case that upheld sterilisation in Virginia, included Justice Oliver Wendell Holmes's notorious phrase "three generations of imbeciles are enough." Similar policies operated across Europe and the Americas. The full picture is documented by historians and is part of why this myth carries unique weight.
What the genetics actually show
Schizophrenia has a substantial genetic component, but the absolute risk to children is often lower than people fear:
- The general population risk is around 1%.
- Having one parent with schizophrenia raises a child's lifetime risk to roughly 10%.
- Having two parents with schizophrenia raises it further, but estimates vary.
- An identical twin of someone with schizophrenia has roughly a 40–50% chance of also developing it — illustrating that even with identical genes, environmental and developmental factors matter.
The NIMH summarises the genetics as polygenic — many small effects combining with environmental factors. Most children of parents with schizophrenia do not develop the condition.
Can people with schizophrenia parent well?
The honest answer is: yes, often, particularly when treatment is consistent and supports are in place. Research on parents with serious mental illness shows wide variability; some struggle, many do well, and outcomes for children depend heavily on:
- Whether the parent is engaged in treatment
- Stability of housing and income
- Presence of a supportive partner or extended family
- Access to mental health and parenting support services
- Avoidance of substance use
The same factors that predict good parenting outcomes in the general population (stability, support, low chronic stress) predict them in parents with schizophrenia. The diagnosis itself is not destiny.
Pregnancy considerations
Pregnancy in someone with schizophrenia is a planned, supported process for many couples today. Key questions usually involve:
- Medication during pregnancy. Many antipsychotics can be continued in pregnancy with shared-decision-making between the patient and prescriber. Stopping medication during pregnancy is associated with significant relapse risk; the FDA's pregnancy and lactation labelling provides risk information.
- Postpartum risk. Schizophrenia has elevated postpartum relapse risk, so a clear postpartum plan with the treatment team matters. See postpartum psychosis and supporting pregnancy with schizophrenia.
- Genetic counselling. The genetic counselling field can give individualised risk estimates without prescribing decisions.
- Sleep, nutrition, and stress. All matter more than usual.
Why the myth persists
- Old stigma. Eugenic-era thinking was never fully dismantled, just made less explicit.
- Selective stories. News coverage focuses on rare cases of harm; the everyday reality of millions of parents living with serious mental illness is invisible.
- Family pressure. Well-meaning relatives sometimes warn against parenthood, often more from fear than evidence.
- Internalised stigma. Many people with the diagnosis quietly assume they shouldn't have children, even when they want them.
What people considering parenthood may find useful
- A treatment team that knows how to manage psychiatric medication in pregnancy
- A genetic counsellor for individualised risk information
- A postpartum plan that includes psychiatric monitoring
- A supportive partner, family, or community
- Realistic budgeting and housing planning
- Early-intervention readiness for any future signs of psychiatric difficulty in the child — not from a place of fear, but of preparedness
The decision to have children belongs to the individual and their partner. Outside parties — including clinicians, family members, and well-meaning friends — can offer information, but should not impose conclusions.
The bottom line
The genetic risk to children of parents with schizophrenia is real but moderate. Many people with schizophrenia raise children successfully, particularly when treatment is sustained and supports are in place. The blanket "you shouldn't have kids" message is a relic of an earlier era's stigma — not a conclusion modern evidence supports.
