Here's where I have the problem. SRS surgery fundamentally stops a human being from performing the biological function of reproduction permanently and forever. FFS, hormones, all that stuff can alter a person, and from what I understand if one were to remove the estrogen, the changes would eventually revert. But Srs is a one and done kind of thing. There is no going back and there won't be any gonads so there would be no sex specific hormones. I can't help but to keep coming down on the side of doctors who would always want the real life experience as a way of determining a person who is wrongly sexed, if you know what I mean.
I think from a medical perspective a doctor will always want to fall on the side of least harm from a risk perspective, therefor it's better to deny the 5 people who may benefit from the 500 who would commit suicide immediately after such an operation. Even if the ratio was lower, I don't think any doctor would be willing to take such a chance. They would rather have 95% satisfied patients than potentially 50% satisfied. It may even affect their ability to practice medicine with enough bad outcomes.
This issue is always 2 sides, what we may want or desire or think may be good for us, and the people on the other side who are saddled with the risks of medical malpractice should it all go sour. So to me in the end, you can wish for anything you want (meaning modify your body at will), but what you can really convince someone to do is something different.
