Abstract: Polycystic ovary syndrome（PCOS） has been studied and discussed as one of the hottest topics for decades since it was firstly described in 1935. Evaluation and management of PCOS have been argued for long time because of its high heterogeneity and complex mechanism. Referring to various international diagnostic criteria and consensus of PCOS， recently a new diagnostic criteria and consensus based on the data of Chinese population has been issued by Chinese Society of Obstetrics and Gynecology，although there were still so many troubles and deviations in application. This review focused on the following topics，pubertal PCOS， diagnosis and typing of PCOS， and the clinic pathway of management for PCOS with infertility. Three of the most popular problems on PCOS practices were reviewed as follows：caution on the diagnosis and management for puberty girls with symptoms like PCOS， interpretation for the Chinese criteria and consensus on typing of PCOS， and emphasis on the opportune clinical pathway of management of PCOS with infertility.
