Women have been left out of the scientific research for decades and, as a result, women's biology is often misrepresented or completely ignored.
The truth is, women's biology is complex. It's cyclic and inconsistent. But once we understand the physiological patterns and mechanisms of action, it becomes evident that feminine biology is a brilliant masterpiece.
Our goal is to demystify feminine biology using good science to empower women and improve women's health systems.
