The National institute for health and care excellence (Nice) is currently holding a consultation on the treatment of gender dysphoria for children and young people. The primary development source which they are relying on is the flawed Cass review. The most likely recommandation is for gender explorative therapy (i.e. conversion therapy). We must show that other evidence displays (can’t contest their developmental sources) that it is ineffective and that gender affirmative approaches are more beneficial. Gender explorative therapy doesn’t support people initially socially transitioning. The evidence you use must be linkable to a measurable metric.

I’m sure there is other research out there which may be beneficial (which I haven’t included in this list). So if you find any more then you should link it in the comments.
