Autophagy is a unique self-degradative process of cell death that directly participates in and influences the onset，progression，and outcome of polycystic ovary syndrome(PCOS).Inhibiting granular cell autophagy，promoting oocyte autophagy，and suppressing theca cell autophagy can effectively prevent and ameliorate ovarian damage in PCOS patients.Both Chinese medicine monomers and compound formulas have been shown to effectively regulate ovarian cell autophagy.
