I do not understand that study. How do the manage to connect the genital nerves to provide a sense of touch here? I am not saying it is impossible, mind you...
They don't actually have to reconnect anything, and what they transplant in doesn't start out with any nerves it seems.
As they explain in the full paper, by seeding the matrix with both epithelial and smooth muscle cells, upon transplantation the tissue underwent vascularization and innervation, aka blood vessels from the surrounding tissue infiltrated, expanded, and integrated into the transplant, and likewise nerves from the surrounding tissue did so as well.
