The Your Vagina Is a Universe
How the Science of the Vaginal Microbiome Can Change Your Life

The vaginal microbiome is the next revolution in women’s health.

There is a living world within that you have yet to discover. Your Vagina Is a Universe introduces you to the vaginal microbiome: billions of microbes that keep the vagina in balance, shift with each menstrual cycle, and are in constant communication with the gut and wider body. This ecosystem shapes how we conceive, how we are protected from infection and disease, and how we age. The vaginal microbiome is one of the most promising frontiers in women’s health, yet most women don’t know it exists.

Ara Katz, science communicator and cofounder of Seed Health, wants to change that. She braids this new research with practical ways to care for your body, guided by what the vaginal microbiome teaches us. You’ll learn to read odor and discharge as information; why infections return; which products help or harm; and how food, sleep, stress, and sex can influence changes in your body across your life, from pregnancy through menopause.

Katz offers a new lens on the body, a new language for what we feel, and an antidote to the vagina’s long history of neglect and shame. A call to understand and to act, the book pairs rigorous science with deep tenderness, inviting every woman to remember the home that is her body.
