or the suicidal 12 year old with long standing gender dysphoria for whom other interventions have been ineffective.
But other interventions have not been taking place. I’m completely against a PB trial, but if this is an argument for who should be included, we need these children to have undergone long term therapy (as in years, not months) to look at the underlying causes of distress and help to resolve them, bearing in mind that puberty itself is the “cure” in many cases- ie even assuming you assume there will be this cohort, we’re years away from identifying who might be part of it.
I don’t see any way this trial could be done in an ethical or safe manner.
