Ignoring the diversity of these experiences and focusing only on those who were effectively “born in the wrong body” could cause harm. That is the argument of a small but vocal group of men and women who have transitioned, only to return to their assigned sex. Many of these so-called detransitioners argue that their dysphoria was caused not by a deep-seated mismatch between their gender identity and their body but rather by mental-health problems, trauma, societal misogyny, or some combination of these and other factors. They say they were nudged toward the physical interventions of hormones or surgery by peer pressure or by clinicians who overlooked other potential explanations for their distress.

The concerns of the detransitioners are echoed by a number of clinicians who work in this field, most of whom are psychologists and psychiatrists. They very much support so-called affirming care, which entails accepting and exploring a child’s statements about their gender identity in a compassionate manner. But they worry that, in an otherwise laudable effort to get TGNC young people the care they need, some members of their field are ignoring the complexity, and fluidity, of gender-identity development in young people. These colleagues are approving teenagers for hormone therapy, or even top surgery, without fully examining their mental health or the social and family influences that could be shaping their nascent sense of their gender identity.
