>>12438263I recall a proof of concept test where lab grown rabbit penises were implanted onto rabbits and two thirds of the rabbits went on to have sex with ejaculation. Lab grown bladders are also used today in humans, granted it is only like 10 people worldwide.
It also stands to reason that non-vital organs will be the first ones to be lab grown and implanted since there's less risk involved, this type of technology could have realistic uses in cosmetic procedures (growing skin, ears, noses) and giving men large penises. The demand for a procedure that gives one a massive penis is enormous.
