A new study discovered a mechanism underlying the benefits of vitamin D supplementation for PCOS.
Polycystic ovary syndrome (PCOS) is a common hormonal disorder, affecting approximately 6%-10% of reproductive-aged women. PCOS is characterized by irregular menstrual cycles, low fertility, polycystic ovaries and excessively high levels of androgens. Androgens are steroid hormones that promote male characteristics. The two main androgens are androsterone and testosterone.
