Therefore, in this experiment, we employed HE staining to assess the impact of moxibustion on the ovarian morphology of PCOS rats, and then the effect of moxibustion on PCOS was observed from the aspects of body weight, serum testosterone level, fasting blood glucose (FBG), serum insulin level, insulin sensitivity index (ISI) and insulin resistance level (HOMA-IR). Here, INS is linked to Insulin resistance.
