Blood: The Science, Medicine, and Mythology of Menstruation by Jen Gunter

Get empowering, period-positive, no-nonsense facts about the science, medicine, and myths surrounding menstruation from Dr. Jen Gunter, New York Times bestselling author of The Vagina Bible !

"The world's most famous and outspoken gynecologist” (The Guardian) fights myths and fearmongering with real science, inclusive facts, and shame-free advice on the topic that impacts more than 72 million Americans every menstruation.

Most women can expect to have hundreds of periods in a lifetime. And yet few are given the tools to understand the science of their own cycle, how it changes over their lifetime, and how it connects to their overall health.

Despite its significance, most education about menstruation focuses either on increasing the chances of pregnancy or preventing it. And while both are crucial, women deserve to know more about their bodies than just what happens in service to reproduction. Instead, the patriarchy has weaponized menstruation through outdated cultural norms, medical dismissal, inadequate menstrual accommodations, and useless products. To distinguish medicine from mythology, people need information. To advocate for ourselves, we need to know how our bodies work. Consequently, many people suffer in silence, thinking their bodies are uniquely broken, or they turn to disreputable sources.


This is the true curse, and the way we break that curse is with knowledge.


In this practical, inclusive guide to menstruation, Dr. Jen Gunter delivers empowerment through knowledge. She explains what’s typical, what’s concerning, and when to seek care, while also examining the historical and social myths which keep women uninformed and disenfranchised. Written with the no-nonsense expertise and frank, fearless wit that have made Dr. Gunter today’s most trusted voice in women’s health, Blood gives women the tools to take back control of their bodies and kick menstrual shame to the curb. Period.
