Why you should listen
Katsuhiko Hayashi is a professor in the department of genome biology at Osaka University’s Graduate School of Medicine, where he leads the team that created mice with two dads, generating viable mouse eggs from the skin cells of two biologically male parents. He is a pioneer of in vitro gametogenesis (IVG), an exciting, experimental and ethically fraught field that could bring species back from the brink of extinction and see the development of "artificial" human embryos.
