A man from Massachusetts has become the first in the United States to undergo a successful penis transplant.
Thomas Manning, 64, had his penis amputated four years ago when he was diagnosed with penile cancer.
It took doctors at Massachusetts General Hospital in Boston 15 hours to complete the transplant, after a penis was provided by a donor.
A 21-year-old man in South Africa became the first to have a successful penis transplant in 2014, after a botched circumcision meant the organ had to be amputated.
Doctors said the heavy psychological toll of losing genitals means the procedure is particularly important.
