Pure scifi until we have a comprehensive mastery of the adaptive immune system and/or can grow whole organ systems in cocultured vats. This would kill any living person you did it to.
I'd say it also has to do with the people most loudly claiming to be trans look like homeless aids victims who dress from a circus clown goodwill. People who just wanna live their lives end up blending in, while the most toxic elements rise to the surface. My suspicion is that the obsession with refusing to call normal trans folks he/she, especially when it is an unprompted response, may be a sign of someone in denial about their desire to plunder tranny butthole. For reference, check out the recently created Theryn Meyer thread , and see how many responses are either garbage tier "He's mentally ill hurr hurr" or " I would SMASH".
So far, all of our ventures in genital transplants have involved simply replacing the parts they already would've had. Male subjects getting penises, female subjects getting vaginas. The path to putting that in practice with humans seems relatively straightforward. Trying to get a male body to accept a vagina or a female body to accept a penis tosses a whole monkey wrench in there that I haven't seen any studies address just yet. The motivation to figure it out is definitely there (humans are weird little fuckers, after all), but I'm not expecting to see the technology come to fruition any time soon.
This is all set dressing without resolving the fundamental problem. People are greedy and want what they can't have. If we master genital transplants, then chromosomes, "girlhood," and every other unattainable quality of biological sex will be coveted instead.
What many people forget in cases like this is that people can want something, set realistic expectations, get it, and come out satisfied. It's all about having a healthy attitude. No material thing can singlehandedly fix a mental health problem, but that doesn't mean we should all stop having material things.
The problem is that changing your sex is not a realistic goal. You can't change your sex. We can invent a surface layer that you can change, "gender," because it had no meaning in the first place, but dysphoria is a desire to change sex. The realistic goal is to tackle the idea it's not acceptable for a man to behave in a traditionally feminine way. And to become comfortable in your own body, because it's not going to change.
Sure, you can't literally change your sex with current technology, and holding out hope for it is unrealistic. But there's also nothing inherently wrong with an adult considering the options available and deciding that surgery is good enough, just like there should be nothing wrong with people finding that psychiatric treatment better suits their needs. Like any other surgery - it's all well and good if you really just want to fix your nose, but if you're a 50-year-old trying to look 20, it's an exercise in futility and public embarrassment.
