The Guardian in London reports that Chinese surgeons have performed the first successful transplant with a donor penis. But according to a 2003 news report, surgeons at Nil Ratan Sircar Medical College in Calcutta transplanted the penis of a 1-year-old who had been born with two to a 7-month-old born without one.
As the Guardian report mentions, there are a number of cases in the medical literature of men who have had their own penises reattached, the most spectacular of which involved the aborted repair of a lawn mower. The surgeons placed the man's organ into his forearm for 30 days while the attachment area healed. They concluded, "In penile amputation, replantation remains the treatment of choice."
There are more details (but not too many) in Dear Playboy Advisor, which includes the best penis questions we have been asked over the years.
