To quote the newly-formed Society for Evidence-Based Gender Medicine (SEGM), a group of 100 international clinicians:

The history of medicine has many examples in which the well-meaning pursuit of short-term relief of symptoms has led to devastating long-term results… The “gender affirmative” model commits young people to lifelong medical treatment…, dismisses the question of whether psychological therapy might help to relieve or resolve gender dysphoria and provides interventions without an adequate examination.

Truth right here.
