Well, that first successful penile transplant that doctors performed several months ago appears to have worked...extremely well!

The 21-year-old man, who has not been identified, had had his penis amputated three years ago to save his life after suffering gangrene from a botched circumcision. In December, Dr. Andre van der Merwe from Stellenbosch University in Cape Town and a team of fellow surgeons performed a nine-hour surgery to transplant what he described as a "good normal penis" harvested from an organ donor.

The doctor told BBC News recently that the patient's girlfriend has reported that she is about four months pregnant and this showed that the "transplant worked."

"This is what we intended, that he should be able to stand up and be able to urinate and have intercourse," Van der Merwe said. "So it is a milestone for him."
