To summarize the treatment of acupuncture for polycystic ovary syndrome （PCOS） in view of scientific principles and basic and clinical data. The relevant literatures have been retrieved through MEDLINE computerization. A control trial of 3 cases indicates ovulation induction of acupuncture. Basic and clinical study verifies that electro-acupuncture （EA） can regulate the disturbed endocrinal, neuroendocrinal and sympathetic nervous systems in PCOS women. It is known publicly that the high-class central activity is enhanced in human body after acupuncture and EA treatment because a series of neuropeptids are released, which is quite important in regulating central and peripheral nerve impulse of hypothalamus-pitu- itary-ovary （HPO） axis and hypothalamus-pituitary-adrenal （HPA） axis E2.31. EA has been applied repeatedly to the women who are diagnosed definitely as PCOS and has been found long-term therapeutic effects on neuroendocrinal parameters and ovulation induction. But, this study has not explained the mechanism of these efficacies. The basic study of laboratory evaluation on EA indicates that the regulation of EA on ovary function is relevant with the adjustment of sympathetic nervous system activity.
