Yes, but with parental permission

No the statistics show that once the transition child comes to a certain age of maturity they fall into deep depression and regret, often leading to mental health issues and even suicide. Aside from that, most procedures leave the patient in long term discomfort. It’s purely sick. It’s not responsible to allow a developing child to make such a decision and it’s definitely not the parents decision either. When the person matures and develops to say the age of 21 then let them decide for themselves at that point. Not before and decided by anyone else on their behalf.
