Have organs ever been successfully transplanted from male to female?
I have never heard of blood being segregated by sex (and yet there would be hormones present).
The brain would have to “learn” the processing/processes perhaps. But the article says that communicating with the new body itself would require relearning (as stroke patients and limb transplant patients must do).
I think some organs have, but they need to be a match. I don’t think this would work for whole bodies. Hey, if they can give me an 18-year old body...
