Polycystic ovary syndrome (PCOS) is a female-specific condition that is far more common than most believe. Even to this day, when I tell people that I work with women with PCOS I would say that 80% of people, men and women, have never heard of it. This is hard to believe when you know that between 10% - 15% of the entire female population has PCOS. This means there are around 300 - 500 million women in this world with PCOS.
