PCOS is an endocrine disorder (disease due to hormonal imbalance) in which there is excessive production of androgen (androgens are usually thought of as male hormone, but the female body also produces a small amount of androgen naturally by the ovaries). It is the condition in which multiple cysts( fluid-filled sacs) are formed in the ovaries. That’s why it is called polycystic and it prevents the ovaries from their normal functioning. It leads to various clinical manifestations such as menstrual irregularities, obesity, infertility, etc.
