A major Finnish study spanning up to 25 years has found that medical gender reassignment for adolescents and young adults under 23 does not reduce their need for specialist psychiatric care.
It also found that in those who underwent hormonal or surgical interventions, psychiatric morbidity increased markedly.
The research, published in Acta Paediatrica on April 4, examined all 2,083 individuals who contacted Finland’s specialised gender identity services before age 23 between 1996 and 2019, matched against 16,643 controls from the general population.
The median follow-up was nearly five years, with some cases tracked for a full quarter-century.
Among those who received medical gender reassignment, 38 per cent of the cohort, the proportion requiring specialist-level psychiatric treatment rose sharply.
For those seeking feminising treatment (natal males) the number of people needing specialised psychiatric help jumped from 9.8 per cent before referral to 60.7 per cent at least two years after.
For natal females transitioning to males, the number went up from 21.6 per cent to 54.5 per cent.
Overall, gender-referred adolescents showed far higher psychiatric morbidity than matched controls both before referral (45.7 per cent vs 15.0 per cent) and afterwards (61.7 per cent vs 14.6 per cent).
Even after adjusting for prior psychiatric history, those who attended gender clinics remained three to five times more likely to need specialist psychiatric care than their peers.
The authors note that psychiatric needs “do not subside after medical gender reassignment” and that, in some individuals, the interventions “appear to be linked to deterioration in mental health”.
Referrals after 2010 showed even greater psychiatric burden, both before and after contact with the services.
Finland was among the first European countries to conduct systematic evidence reviews of “gender-affirming” care for minors.
Its national guidelines already prioritise thorough assessment and treatment of co-occurring mental health conditions over routine hormonal or surgical interventions, especially for those whose gender distress emerged or intensified during adolescence.
The country’s two gender clinics have adolescent psychiatry departments, reflecting the recognition that most young people presenting with gender dysphoria have significant underlying psychological issues.
This latest study adds to a growing body of Finnish research – including earlier work on functioning, suicide mortality and desistance risks – suggesting that medical transition does not address the broader mental health challenges faced by this population.
Suicide rates, while elevated compared with the general population, were largely explained by pre-existing psychiatric morbidity rather than gender dysphoria itself.
Supporting the study’s results are its nationwide scope, use of objective register data rather than self-reports and long follow-up period.
It arrives as several European countries – including Finland, Sweden and England – have restricted or paused routine medical transitions for minors pending better evidence, shifting emphasis towards holistic mental healthcare.
Observers note that the findings challenge the assumption that gender transition is a straightforward solution to psychological distress in youth.
Critics, including some LGBTQ-activist commentators, claim the increase in psychiatric contacts reflects heightened monitoring and surveillance bias inherent in Finland’s integrated care model, rather than genuine worsening.
They also point to the journal and question aspects of the methodology.
The researchers themselves caution that longer-term outcomes remain uncertain and call for continued careful assessment of co-occurring conditions such as autism, depression, anxiety and trauma.
In their view, medical gender reassignment alone appears insufficient to resolve – and in some cases may fail to prevent the intensification of – the serious psychological problems that frequently accompany adolescent gender distress.
“The considerable severe psychiatric morbidity prior to contacting the gender identity services, and its increase over time, suggest that for some of these adolescents, gender dysphoria may be secondary to other mental health challenges,” the authors wrote in their conclusion.
“This underscores the need to thoroughly assess and appropriately treat mental disorders among those seeking gender reassignment before and after undergoing irreversible medical treatments.
“Psychiatric needs must be adequately met.”
