Objectives To evaluate the methodological bias and the reliability of the conclusions of systematic reviews on acupuncture for polycystic ovary syndrome. Methods We comprehensively searched PubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data to collect systematic reviews on acupuncture for polycystic ovary syndrome from the establishment time of databases to January 5th, 2018. The AMSTAR tool was applied for methodological quality assessment of included studies and the GRADE system was applied for evidence quality assessment of included outcomes of systematic reviews. Results A total of 11 systematic reviews were included. The results of assessment using AMSTAR showed that, among the 11 items, most problems occurred in Item 5 " Were there any lists of research articles included and excluded”, followed by Item 1" Was an‘a prior’design provided?”and Item 11" Were potential conflict of interest included?”. GRADE grading results showed that quality of evidence for the outcome measure were" low”or" very low”. Conclusions Current acupuncture treatment of polycystic ovary syndrome has a certain effect, however, the quality of evidence is low. Thus, physicians should apply the evidence to make decision on acupuncture for polycystic ovary syndrome with caution in clinical practice and consider the actual situation, combined with the patient’s value preferences and economic factors.
