That's one small step for rabbit penises, and potentially one giant hop for restorative surgery. An experiment that gave rabbits lab-grown penises capable of fathering offspring won the most votes in msnbc.com's 2010 Weird Science Awards contest. Cells of penile tissue were grown on scaffolds of cartilage. When the creations took on the right shape, they were grafted onto rabbits that had their penises removed. After the transplants, the rabbits were able to breed ... like rabbits. The procedure could someday be used to heal humans as well. The photos at right show an experimenter working on the penile tissue, and an X-ray image of the restored penis.
