What is the cause of poly cystic ovaries syndrome?

HCAS.: Pcos is best described at hcas - hyperandrogenism and chronic anovulation syndrome. It is frequently the result of obesity that produces excess androgens from the subcutaneous fat deposed all over the body; that in turn inhibits monthly ovulation starting a vicious circle of hormonal imbalance that can only be stopped with weight loss and/or metformin/ocps.
