September is PCOS Awareness Month. Polycystic Ovary Syndrome, often shortened to PCOS, is a hormonal condition where your ovaries produce excess hormones. This results in a hormonal imbalance that can cause irregular menstrual cycles, high androgen levels, and cysts in the ovaries. According to the World Health Organization, PCOS affects 8-13% of reproductive-aged women, but up to 70% of affected women go undiagnosed worldwide.
