How come we can transplant a lot of organs from organ donors but we can't donate genitals for gender reassignment surgery?

If I died, I'd be more than glad to donate my dick and balls to someone who wanted to become a male. Why can't we take genitals from dead men and women for gender reassignment surgery?

the genitals have a really extensive nerve and blood supply which would be a nightmare to transplant.  That said, so does the face, and face transplants have advanced amazingly since 2005, so it could be something they figure out in the future.

however, so much of your genitals are involuntarily controlled by your emotions and brain, so all the nerves would have to be matched up just right for it to function.  Liver and kidney are controlled moreso by chemicals, not emotions like getting an erection, so the nervous attachment would be a lot more complicated.
