Big Study Finds that “Gender-Reassignment” Wrecks Mental Health

Lawmakers, judges, activists, and doctors trying to justify “gender-affirmation” treatments in children have been using the argument that the scientific consensus supports their and that failure to offer them risks serious psychological harm to children in need of them.

But now a major, large-scale medical study from Finland–which is definitely not a conservative bastion–shoots all of that down.  This is high quality research, not only because of the sample size and the long term monitoring but because, following the scientific method unlike most such studies, it was a controlled study.  That is, it compared the results of individuals who got the treatments with those who did not get the treatments.

Here are some of the findings, from the study itself, Psychiatric Morbidity Among Adolescents and Young Adults Who Contacted Specialised Gender Identity Services in Finland in 1996–2019: A Register Study, published in Acta Paediatrica (my emphasis):

Gender-referred adolescents showed significantly higher psychiatric morbidity than controls both before (45.7% vs. 15.0%) and ≥ 2 years after referral (61.7% vs. 14.6%). Those referred after 2010 had greater psychiatric needs than earlier cohorts, both before (47.9% vs. 15.3%) and ≥ 2 years after (61.3% vs. 14.2%) referral. Among adolescents who underwent medical gender reassignment, psychiatric morbidity increased markedly during follow-up—rising from 9.8% to 60.7% in feminising gender reassignment and from 21.6% to 54.5% in masculinising gender reassignment. After adjusting for prior psychiatric treatment, all gender-referred adolescents had similarly elevated risks of psychiatric morbidity, with hazard ratios approximately three times higher than female controls and five times higher than male controls.

In other words, young people who seek treatment for gender dysphoria tend to have other psychiatric problems (particularly, as the study says elsewhere depression and anxiety), and those problems increase after they get treatment.  Those who have medical interventions–that is, hormone treatments and sex-reassignment surgery–have increased psychological problems.

But what about those other studies that purport to show how helpful these treatments are?

The bulk of the literature on adolescent GD [gender dysphoria] suffers from two very common shortcomings: A lack of control groups, making it unfeasible to estimate truly excessive morbidity, and small sample sizes that leave room for chance variation. . . .

Medical GR [gender reassignment] is often suggested to be beneficial, even vital, for the mental health of adolescents suffering from GD, but the evidence supporting subsequent improvements in mental health, quality of life or functioning is very limited. Many of the studies in this field are cross-sectional and unsuitable for assessing developments. The few longitudinal studies have been of low quality and provided inconsistent results. The sample sizes have been small; there usually has been no control group, follow-up periods have been short, and the measures of assessing changes in mental health have varied. Loss to follow-up has often been substantial.

So let’s follow the science.
