Pigs, rabbits get 3D-printed penis to restore erectile function in a ‘world-first’ | The penile implants enabled the rabbits and pigs to mate and reproduce biologically within weeks after the surgery.
3D-printed models of the penis can facilitate the study of penile physiology and the repair of penile defects, as shown via a reconstructed and implanted corpus cavernosum that restored erectile function and mating capacity in rabbits and pigs.
Recruitment of intracavernously injected adipose-derived stem cells to the major pelvic ganglion improves erectile function in a rat model of cavernous nerve injury. Ferretti, L. et al.
