Wake Forest University’s Institute of Regenerative Medicine, which has successfully grown human bladders in the lab using only a few extracted cells sprayed onto a chemical frame that mimics the body’s tissues, has so far been unsuccessful at regenerating penises because of the organ’s complexity.
However, it announced in a November journal article a success with rabbit penises. Four of the 12 rabbits with lab-grown phalluses successfully impregnated females, and in an unexpected finding, the new penises appear not to lessen sexual desire, in that all 12 of the rabbits began mating within one minute of meeting females.
