Artemisinin has been widely used as a first-line antimalarial drug in routine clinical
practice. In recent years, it has been reported that Artemisinin also has some significant
anti-inflammatory, anti-tumor and immune-modulating effects. The investigators' previous
studies discovered that Artemisinin dramatically reduced serum androgen levels and improved
poly-cystic ovary syndrome(PCOS) in animals. Preliminary study by the investigators found
that artemisinin derivatives are capable of reducing both androgen levels and improving
insulin resistance, two clinical characteristics of PCOS. Thus artemisinin derivatives has
the potential effect to alleviate PCOS symptoms. The current study aims to investigate the
effect of artemisinin on improving PCOS and serum androgen levels in PCOS subjects.
