What the studies show

Clinic follow-up studies of gender-dysphoric children consistently find that for most, gender dysphoria resolves by adolescence or adulthood without medical transition. The largest followed 139 boys seen in Toronto at about age 7 and reassessed them at about 21: 87.8% no longer had gender distress, including 86.4% of those who had met the full childhood diagnosis, while 12.2% still did (Singh et al., 2021). In Amsterdam, 63% of 127 children referred before age 12 no longer had gender dysphoria by their mid-teens; it persisted more often in girls (50%) than boys (29%), and persistence was associated with more intense childhood distress and with having socially transitioned (Steensma et al., 2013). Most desisters in these studies grew up same-sex or bisexually attracted. A compilation of 11 such studies put desistance at roughly 60% to 90% (Cantor, 2016). German insurance records point in a similar direction among older youth: only 36.4% of those diagnosed in 2017 still carried the diagnosis five years later (Bachmann et al., 2024).

Studies of socially transitioned children report the opposite pattern. Of 317 children who fully transitioned at ages 3 to 12, 94% identified as trans about five years later and about 60% had started blockers or hormones (Olson et al., 2022). Whether this reflects the children selected for transition or an effect of transition itself is the central unresolved question. Social transition has been argued to be an intervention that likely increases persistence (Zucker, 2020), while a study of 85 children found those who later transitioned already identified strongly with the other sex beforehand (Rae et al., 2019). A systematic review found no study following children forward with a suitable comparison group and concluded that neither benefit nor harm of social transition has been shown (Hall et al., 2024).

Limits of the evidence

The desistance studies drew on single clinics and older, broader diagnostic criteria that included milder cases, often under therapy aimed at reducing cross-gender behavior, and in Amsterdam the 80 children who did not return were counted as desisters. The persistence studies used volunteer, mostly affluent and supportive families, with no formal diagnosis and short follow-up. Neither body of evidence reflects today's caseload, which is predominantly adolescent girls, and none can separate the effect of transition from pre-existing differences between children.
