A group of researchers report they successfully created artificial penises in rabbits by taking cells from the animals, growing the penile tissue in a lab, and then reimplanting it into the rabbits. Clearly this is encouraging news for owners of pet rabbits who suffer from erectile dysfunction. But does this mean the artificial penis will one day be available to humans and possible replace drugs like Viagra? Possibly. "We don't quite understand why it works, and it has yet to be replicated in anything more sophisticated than a rabbit," says one fertility expert at NYU. But "this could be a huge advance in the treatment of erectile dysfunction," says another. Talk to your doctor to find out if an artificial penis is right for you. Just wait about a decade to do so.
