To comprehensively understand the current status of animal model of polycystic ovary syndrome(PCOS) in China，to make animal modeling more rigorous and scientific in the future.Methods:Related literature in China National Knowledge Infrastructure(CNKI)，Chinese Science Citation Database(CSPD) and Chinese Citation Database(CCD) from January 1，2017 to March 10，2021 was retrieved，and the animal species and drugs used for PCOS modeling，as well as the modeling duration and model evaluation were analyzed.Results:Rats aged 21～24 days were most used for PCOS modeling by androgen and letrozole.The most modeling duration was 20～30 days.Shed cell of vaginal smears，biochemical indexes and pathological indexes were selected for model evaluation.Conclusion:As there are various PCOS modeling methods，mature modeling methods should be selected as far as possible in animal modeling.Moreover，researchers should continuously explore new modeling methods and establish PCOS animal models that are more consistent with clinical characteristics.
