I could be missing something, but I have read all of your comments here, and I don't see you linking any studies.

What is this article you speak of? Please attached your link to this study directly so I know what you are talking about.

Trans people who undergo HRT (what I assume you are calling chemical castration) undergo the treatment with informed consent. They are aware of the permanent changes it does to then body and have to sign off on it. I don't know anyone who thinks that HRT is "reversable."

True, if you stop HRT, you may stop having some of the characteristics, but there's a good shot you've already lost any fertility and may of the changes are permanent. No one is pretending HRT is 100% reversible. No one is out there trying to convince people they need to transition. Transition is a personal choice some people make, under informed consent.
