I am only aware of smaller studies such as this that are about generalized mental health. This is definitely something that needs more funding.

I have worked with and met hundreds of people who transitioned. There is an extensive problem of suicidal ideation amongst people who are denied medical treatment for one reason or another. It is almost universal that they are suffering stress, depression, anxiety, and/or PTSD directly resulting from the effects of going through a puberty they didn’t want, and the resulting discrimination from that.

I have never seen a case of someone who merely had puberty delayed before transitioning regretting it. I can’t say that it never happens, as everyone is their own person. While I do personally know people who have died after being denied medical coverage for transition.

It makes sense to strive towards filtering out those who don’t need medical intervention, just don’t completely block those who actually do need it. Cutting funding for medically necessary treatment is also a form off blocking since many can’t afford it otherwise.

Even if there was a cherrypicked case out there, the vast majority of suicides are by those who are denied medical treatment and/or suffer discrimination.

By forcing puberty, politicians are forcing these teens to face a future where for example they have to live as a woman with a male sounding voice or beard. Needing more expensive and painful treatments to partially reverse such as facial feminization surgery. That is life full of discrimination and didn’t have to be.
