3D-printed perfused models of the penis for the study of penile physiology and for restoring erectile function in rabbits and pigs

3D-printed perfused models of the penis for the study of penile physiology and for restoring erectile function in rabbits and pigs

The intricate topology of vascular networks and the complex functions of vessel-rich tissues are challenging to reconstruct in vitro. Here we report the development of: in vitro pathological models of erectile dysfunction and Peyronie’s disease; a model of the penis that includes the glans and the corpus spongiosum with urethral structures; and an implantable model of the corpus cavernosum, whose complex vascular network is critical for erectile…

World’s first 3D-printed penis restores sex spark in pigs, rabbits

The penile implants enabled the rabbits and pigs to mate and reproduce biologically within weeks after the surgery.

World’s First 3D-Printed Penis Implant Successfully Restores Function in Pigs and Rabbits

Advancements in 3D bioprinting have taken a bold new step: a team of researchers from China, Japan, and the United States has successfully 3D-printed a fully functional penis and implanted it into rabbits and pigs, with promising results. This cutting-edge breakthrough in regenerative medicine could transform treatments for penile malformations, erectile dysfunction, and other sexual disorders. Engineering a Functional Organ with 3D Bioprinting …
