We’re in an age of organ transplants so it was inevitable we’d get around to penises. Dr Anthony Atala has been working on the problem since 1999 and he’s had considerable success – in rabbits.
No human beings so far, but his team at the Wake Forrest Institute in North Carolina, US is close. Another five years, they say.
Which is very good news for any man who has lost his penis either through genital defects, injury or perhaps surgery for an aggressive case of penile cancer.
At present the only treatment option for these men is to have a penis constructed with skin and muscle from the thigh or forearm. Sexual function can be restored with a prosthesis placed inside.
