ABSTRACT：Polycystic ovarian syndrome (PCOS) is a prevalent reproductive endocrine metabolic condition in women of childbearing age.Insulin resistance is a key pathogenic feature of polycystic ovarian syndrome. Hyperinsulinemia and hyperandrogenism have a simultaneous effect on reproductive axis function, resulting in follicular development abnormalities, infertility, and lipid metabolism disorders. Duntulishui Acupuncture is used to treat the etiology and pathogenesis of PCOS patients who have spleen and kidney deficiency, as well as to prevent water from accumulating. According to the five-element theory, it focuses on Guanyuan, Zhongji, Sanyinjiao, Zusanli, and Fenglong, treats the spleen and kidney together, promotes qi and water, and regulates the cycle in conjunction with ovarian physiology, with the goal of regulating glucose and lipid metabolism, alleviating insulin resistance, promoting follicle development, and improving ovarian function.
