If you read the story, you see that the transplant was a success. It was "psychological concerns" (the wife) that made them take it back off. I could understand, but still...
"Hey, I just got one finally put back on and now you want it back off?!?"
That would be horrible. I guess she was having trouble coming to grips...wait, that's a bad choice of words...she was having trouble with the idea of another man's penis in the place of her husband's. Was weird for her (and him too, I imagine).
That's a pretty devoted, loving husband, because if you asked most men: "your wang or your wife",
somebody's gonna be packing a suitcase later that evening.
"Hell, I can get another wife...".
