Hormonal birth control creates pervasive changes in a woman's body from top to bottom, including the brain.

In this episode of Bulletproof Radio, I talk with Sarah E. Hill, Ph.D., who leads research in the rapidly expanding field of evolutionary psychology. She’s currently a professor and research psychologist at Texas Christian University studying the effects of hormonal birth control on women.

She’s also the author of the book: “This is Your Brain on Birth Control: The Surprising Science of Women, Hormones, and the Law of Unintended Consequences.” It’s an enlightening read that verifies what millions of women have always suspected, but no one confirmed for them until now: The pill changes women.

“Is the best way to prevent pregnancy to totally rewrite everything that creates the experience of being a who a woman is?” Sarah asks.

With more than 50 scientific publications and multiple prestigious research grants to her credit, Sarah has become an authority on the application of evolutionary ideas to human behavior and psychology. She’s been quoted in The New York Times, The Washington Post, Scientific American and The Economist.

“Our sex hormones are part of the signaling architecture that our brain using to create the experience of being the person that we are,” Sarah says. “When we change women’s sex hormones—which is what we do with the birth control pill—it’s going to change all sorts of activities in terms of psychological functioning.”

In our interview, Dr. Hill shares her incredible research findings that has uncovered the many ways that the pill changes women’s brains, bodies and lives.
