Hang on, hang on, are you sure puberty blocking drugs are reversible? I think you may be wrong there. Blocking hormones at a key stage in development is going to have a long term impact. For one thing, the size your todger increases considerably around that age. There is also going to be potential long term impacts on bone health, muscular development, prostate health, testicular development and fertility. The purpose of puberty blocking drugs is not to delay development of secondary sexual characteristics, it is to prevent them.
Personally, I would make such treatments illegal to administer to children. People that have had not been happy with their gender have traditionally had a very long line of doctors willing to use them as their guinea pigs wanting to make their name on the back of their condition. I was talking to a doctor the other week in relation to a penis related project that I am working on. He was telling me that actually the leading area of medical study into the penis at present is working out how to change the whole penis structure into a usable third type of sex organ for those who do not wish to be men. There are all kinds of insane looking surgical procedures being suggested. It seems like a free for all. Ultimately, surgery is only ever going to be a hack and slash job. It seems like medical science lead by social pressure rather than accepting the medical reality of the situation.
It is a tricky area when it comes to adults, because I think a lot of the time they are willing victims. I don't think that the mental area is explored to its full extent. There is considerable correlation between mental illness and long term mental problems even after procedures have been carried out. But kids usually can not appreciate the long term impact of a decision such as that to take hormone blocking drugs. I suspect there are a lot of kids once they actually go through puberty that their gender identity becomes very firmly male, and the issue goes. I suspect it is not as well documented because effectively they are not the ones with the problem. I think there is also a tendency to ignore that tieing together gender, which is a social construct, and sex, which is the biological status, is something that is probably learned. I would rather medicine encouraged people to accept their sex and let them know that they could live whatever gender they wish.
Penis related project? With that username?
