In 2017, a scientist and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one. How and why could this happen? What is hijacking our fertility and our health?

The scientist who led that research team, Dr. Shanna Swan, joined us with her coauthor Stacey Colino in a conversation facilitated by Town Hall Senior Correspondent Steve Scher to unpack these startling discoveries. As contained in her book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race, Dr. Swan and her team examined 185 studies involving close to 45,000 healthy men. She and Colino shared what they discerned about how both lifestyle and chemical exposures are affecting our fertility, sexual development, and general health as a species. With accessible explanations of the threats and repercussions, they presents an urgent wake-up call to action in protecting our future.
