Scientists at the Wake Forest Institute for Regenerative Medicine could be offering new hope to men with genital abnormalities or injuries in as little as five years, thanks to one of their many tissue engineering endeavors: lab-grown penises. While that may sound a little far-out, these guys are among the world leaders in regenerative medicine and they've achieved some remarkable things in the past. Back in 1999, they became the first in the world to successfully implant a lab-grown organ into humans—a bladder.
