Why Autism and Gender Dysphoria Travel Together

Transgender people are 3–6 times more likely to have autism than their cisgender peers, and it is expressed differently

Background

Autism and gender dysphoria co-occur far more often than chance would predict. Transgender people are 3–6 times more likely to receive an autism diagnosis than cisgender people.

This narrative review synthesizes the current evidence on why the two conditions overlap and what clinicians need to know.

Results

The overlap is consistent across age groups and study designs. Adolescents with autism are about twice as likely as neurotypical teens to identify as transgender. In children, formal gender dysphoria diagnoses occur more than four times as often in those with autism.

Autistic people of female-birth show the highest rates of transgender identity and non-heterosexual orientation.

People managing both identities face compounded challenges: higher rates of anxiety, depression, suicidal thoughts, and self-harm than those with either diagnosis alone. Some describe autism as a barrier to gender affirmation. Sensory sensitivities, for example, can make binding or hormone-related body changes intolerable. Others say autism helped them understand and accept their gender identity.

Why the two conditions overlap isn’t settled. Proposed explanations include differences in theory of mind, less cognitive flexibility, elevated prenatal testosterone, and overlapping cortical anatomy. None of these fully explains the association.

Practice Implications

1. When a patient discloses a transgender identity, ask about autism history, and vice versa.
2. Autistic patients may describe gender dysphoria differently, communicate distress less directly, or need more time in the diagnostic process. Use concrete language, avoid ambiguity, and confirm understanding.
3. Autism is not a contraindication to gender transition and doubting a patient’s transgender identity because they have autism crosses an ethical line.
