What does sex have to do with human reproduction? Within the next 20 to 30 years or so, perhaps not much. At least that's how Henry T. Greely sees it. He's the Director of the Center for Law and Biosciences at Stanford University. He's also the author of a new book called The End of Sex and the Future of Human Reproduction. In this edition of Up Next, Greely talks about the coming revolution in reproduction, which, he says, will not only increasingly divorce sex from making babies, but also give parents more and more control over what genes their children will have.
