All gender affirming care that is or has been provided to minors at scale is reversible. The standard for providing gender affirming care to minors is puberty blockers and social transition, never anything permanent like surgery. Personally, I don’t see any cause for concern about potential harm to minors from providing gender affirming care, but I do see the harm that is done to them when that care is denied and find it far more concerning given that a common result of that harm is the most permanent and irreversible outcome possible, suicide.
