In this episode we head into the future to learn about a controversial technology that could change the face of reproduction. Researchers are developing a technology called in vitro gametogenesis (IVG), which can reprogram human cells–like a skin cell–to become eggs or sperm. With IVG we could reach a future where anyone could produce either eggs or sperm, in potentially limitless quantities. This could open up a whole world of new options for how humans reproduce. Startup companies are working to bring this science to the public in ways that bypass the usual research routes for new reproductive technologies. When would it be ethically acceptable to try IVG to make a baby? How can we ensure the technology will be used ethically, including how it should be regulated?
