Radiolab Presents: Gonads

Radiolab Presents: Gonads is a multi-episode journey deep into the parts of us that let us make more of us. Longtime staff producer and host Molly Webster explores the primordial roots of our drive to reproduce, introduces a revolutionary fertility procedure that sounds like science fiction, reveals a profound secret about gender that lives inside all of us, and calls on writers, educators, musicians, artists and comedians to debate how we’re supposed to talk to kids about sex.

Check out Misconceptions, part of a special exploration of fertility and reproduction from Romper & Radiolab.

Radiolab is supported in part by Science Sandbox, a Simons Foundation initiative dedicated to engaging everyone with the process of science. And the Alfred P. Sloan Foundation, enhancing public understanding of science and technology in the modern world. More information about Sloan at
