Effect on Guizhi-Fuling decoction and Danggui-Shaoyao decoction combined with metformin for follicle numbers and ovarian volume of fueling the polycystic ovarian syndrome

Objective To evaluate the efficacy of Guizhi-Fuling decoction and Danggui-Shaoyao decoction combined with metformin in patients with polycystic ovarian syndrome. Methods A total of 120 patients with fueling the polycystic ovarian syndrome were enrolled and divided into two group by random number table method, the treatment group (60 patients) and the control group (60 patients). Patients in the control group were treated with metformin, and those in the treatment group with Guizhi-Fuling decoction and Danggui-Shaoyao decoction plus metformin for 6 menstrual cycle. The vagina or rectum two-dimensional ultrasound was detected by follicle numbers (FN) and ovarian volume (OV). The height, weight, BMI calculation were recorded and evaluated before and after treatment. Results After treatment and follow-up, the OV (2.4 ± 1.5 cm3vs. 4.7 ± 2.6 cm3, t=5.935; 1.6 ± 0.8 cm3vs. 2.9 ± 1.3 cm3, t=-6.597), FN (8 ± 2 vs. 10 ± 2, t=-5.477; 6 ± 1 vs. 8 ± 2, t=-6.928) and BMI (20.5 ± 2.6 kg/m2vs. 23.8 ± 2.7 kg/m2, t=-6.866; 20.1 ± 1.3 kg/m2vs. 22.6 ± 1.7 kg/m2, t=-9.074) of the treatment group were significantly lower than those of the control group (P<0.01). Conclusions The Guizhi-Fuling decoction and Danggui-Shaoyao decoction combined with metformin can reduce the weight, ovarian volume, follicle numbers of PCOS patients.
