Researchers at Wake Forest University in North Carolina constructed a functional male genitalia in rabbits that allowed the animals to mate and produce offspring. The research could someday lead to normal penile function in men with damaged erectile tissue.
On a collagen scaffold, which provided the organ structure, Atala and his group grew smooth muscle and endothelial cells, the same cells that make up blood vessels, harvested from rabbit erectile tissue.
The scaffold and cells were implanted into 12 rabbits, where the tissue continued to develop .
Someday F2M transgenders will be able to be the men/man they always wanted to be.
