Chinese herbal medicine for subfertile women with polycystic ovarian syndrome.

Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, affecting 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives and insulin sensitizers, have been widely used to improve the symptoms and signs for PCOS. Recently, many studies have been published considering Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS.
