There are a lot of ciswomen who have their ovaries removed for any number of reasons. My housemate had hers removed several years ago and she's still alive. She did go through a short amount of time where she said she felt like a robot, just emotionless, and was briefly suicidal until her doctor prescribed some oestrogen tablets. So I doubt just removing the source of sexual hormones would kill anyone, especially when it comes to transmen who are supplying their own hormones via injections, creams, gels, patches, etc.
This does sound very interesting, although I think it would be much easier if biologists would find a way to clone a penis and testicles using a trans man's own tissue samples. A Build-A-Cock workshop, if you will. Create a cock. Harvest. Put patient under. Slice and dice. Connect the appropriate nerves and blood vessels. Suture and glue. Shove Percocet down throat. Allow time for healing. Introduce trans man to hand lotion, tissues, and adult videos. Wait. Log results. Make adjustments where needed. Try and try again until you get it just right. Celebrate with pizza, ice cream, and beer. Repeat.
And yes, I do believe this can and will happen. They're probably working on it right now, as we speak, in some underground laboratory. Blokes are so hung up about being hung, you know they're working hard to perfect penis processes. Guys lose their genitals all the time because we're stupid and do stupid things with our willies. Then you have some guys that are born with misshapen or defective genitals. Loads never quite develop their junk and are self-conscious about it. Then there are many who are just peeved that Mum and Dad allowed some git to mutilate their tools at birth via circumcision. [I know I would be pissed!] So there are a hundred reasons why this needs to be funded, and reason #101 is so that trans men can finally attain their true forms.
That, and I think it'd be hilarious to slap someone in the face with my junk.
