What the trial is, and whether it could suit you

Gender dysphoria (GD) is a significant suffering lasting more than 6 months in a subject, with regard to the discrepancy felt between his or her gender identity and his or her birth sex.

International best practice guidelines recommend early treatment from the start of pubertal development to block pubertal progression, with the possibility of hormonal transition by administering sex hormones of the desired sex usually around the age of 15.5. However, in order to reduce the psychosocial consequences of GD, more and more referral teams are carrying out this transition from the age of 13.5, although no study has been published to show its benefit compared with a transition at the age of 15.5.
