Yeah, I think having one would be better than nothing. I do wonder if it still works normally or if it needs lots of structural help (medicinal or pumping or whatever). Or maybe it only works for peeing and “appearing normal.” We might have to wait to see what this first guy reports.
What if he finds out his junk now responds to the donor’s “fantasies?” That could be weird. “Hey, suddenly I’m into women with hairy armpits and legs!” I may be up too late even to think such weird stuff.
Other transplant recipients have reported acquiring tastes and preferences of deceased donors so it’s not totally out of the question although just how that might be the case is beyond my ability to reason it out. Epigenetics? You got me.
There are transplant recipients who report full function, although patients in the position of the man in this article would have to be on testosterone treatment for life to maintain functionality.
There is a doctor near here who has pioneered regrowing them on a collagen “lattice,” although some penile tissue must remain in order to get the cell culture to repopulate that “lattice.” I guess you could grow one as big as you wanted via that method, lol.
