Scientists Grow Artificial Penis in Lab

It's now possible to replace a defective, damaged, or diseased penis with a penis grown in a laboratory - in rabbits.

The new penises have blood vessels and nerves that allow them to become fully functional. Indeed, the replacement penises worked like a charm. The rabbits were able to get erections, mate with females, and get females pregnant with normal, healthy pups.

While human trials are still far off, recent accomplishments make this goal highly credible.
