Chinese surgeons have performed the world's first penis transplant on a man whose organ was damaged beyond repair in an accident this year. The incident left the man with a 1cm-long stump with which he was unable to urinate or have sexual intercourse. Doctors spent 15 hours attaching a 10cm penis to the year-old patient after the parents of a brain-dead man half his age agreed to donate their son's organ. The procedure, described in a case study due to appear in the journal European Urology next month, represents a big leap forward in transplant surgery; it required complex microsurgery to connect nerves and tiny blood vessels. The surgical team claims the operation was a success.
