OBJECTIVE: To observe the efficacy of Danzhi Xiaoyao Pill (DXP) in anovulation infertility patients with polycystic ovary syndrome (PCOS) of pathogenic fire derived from stagnation of Gan-qi (PFDSG) complicated insulin resistance (IR). METHODS: Sixty PCOS patients were randomly assigned to two group, the integrative medical treatment group (Group A) and the Western medical treatment group (Group B), 30 cases in each group. All patients took Metformin and Diane-35. Those in Group A took DXP additionally. The therapeutic course for all was 3 menstrual cycles. After treatment the ovulation was induced by oral administration of letrozole or injection of menotropins (HMG). The therapeutic efficacy was compared between the two groups. RESULTS: The levels of insulin, luteinizing hormone, and testosterone were obviously lower after treatment than before treatment in the two groups (P < 0.05). There was no statistical difference between the two groups after treatment. There was no statistical difference in body mass index (BMI) between the two groups before and after treatment (P > 0.05). Better effects were obtained in Group A in improving symptoms such as agitation and irritability, fullness in the chest and hypochondrium, swollen pain in the breast before menstruation, bitter and dry mouth, oligomenorrhea, abnormal color and amount of menstruation, and pulse and tongue (P < 0.05, P < 0.01). The ovulation rate was 86.1% (93/108 cases) in Group A, obviously higher than that in Group B (65.5%, 74/113 cases). The clinical pregnancy rate was 60.0% (18/30 cases) in Group A, obviously higher than that in Group B (36.7%, 11/30 cases), showing statistical difference (P < 0.05). CONCLUSIONS: DXP could improve the ovulation rate and the pregnancy rate in anovulation infertility patients with PCOS complicated IR. It also could significantly improve Chinese medical syndromes, showing obvious advantages over using Western medicine alone.
