Our guest is Dr. Jen Gunter, who is board-certified in OB/GYN and pain medicine, and who writes about the intersection of women's health, sex, science, and pop culture for The New York Times. She joins us via Skype to discuss her new book, which is her second: "The Vagina Bible." Does eating sugar cause yeast infections? Does pubic hair have a function? Should you have a vulvovaginal care regimen? Will your vagina shrivel up if you go without sex? What's the truth about the HPV vaccine? Such are the questions explored in this thorough, useful, myth-busting, and best-selling book.
