Abstract：Polycystic ovary syndrome(PCOS)is a common reproductive endocrine disease characterized by hyperandrogenemia,insulin resistance,ovulation disorders,and polycystic changes in the ovaries.Exosomes,as key mediators of intercellular communication,carry microRNAs(miRNAs)that play a crucial role in the pathogenesis of PCOS.Exosomal miRNAs participate in the glycolysis process of granulosa cells,improve energy metabolism disorders,affect the proliferation of granulosa cells and follicular development,and improve the local ovarian inflammation response by influencing macrophage polarization.Meanwhile,the abnormal expression of exosomal miRNAs is closely related to hyperandrogenemia,adipocyte differentiation,and insulin resistance.These findings reveal that exosomal miRNAs are involved in the occurrence and development of PCOS by regulating granulosa cell function,inflammatory response,hyperandrogenemia,and metabolic processes,providing new targets for its diagnosis and treatment.
