Abstract： Objective： To study the effect of the therapy of Bushen Huoxue prescription combined with ovulation induction medicines on serum estradiol(E2)， endometrial thickness， serum anti- mullerian hormone(AMH)， and rates of ovulation and pregnancy in patients with polycystic ovary syndrome of kidney deficiency and blood stasis type. Methods：A total of 78 polycystic ovary syndrome patients who met the inclusion criteria were randomly divided into two groups，with 39 cases in each group. The control group was treated with clomiphene and 5 000-10 000 U of HCG was injected on the day of HCG injection； the combined administration group was additionally treated with Bushen Huoxue tang based on the treatment of the control group. Both groups were treated for three menstrual cycles，and the curative effects were evaluated after treatment. Serum levels of E2 and AMH before and after treatment were detected，and endometrial thickness on HCG injection day was measured. The final rates of ovulation and pregnancy of selected cases were followed up and counted，and the collected data were comprehensively analyzed. Results： Compared with the same group， there was no significant difference being found in the comparison of serum E2 before and after treatment(P＞0.05)，and after treatment，there was no significant difference being found in the comparison of serum E2 between the two groups(P＞0.05). After treatment， the serum E2 levels in the two groups on the day of HCG injection were higher than those before injection，and the above level in the combined administration group was higher than that in the control group， differences being significant(P＜0.01). After treatment， the endometrial thickness on the day of HCG injection was(9.37 ± 3.04) mm in the combined administration group，and(6.60±2.19) mm in the control group，the difference being significant(P＜0.01). Compared with the same group， there was no significant difference being found in the comparison of serum AMH before and after treatment(P＞0.05)；after treatment，the level of AMH in the combined administration group was lower than that in the control group，the difference being significant(P＜0.05). After treatment，the differences between the rates of ovulation and pregnancy in the two group were significant(P＜0.05)， and the above rates in the combined administration group were better than those in the control group. Conclusion： Bushen Huoxue prescription can effectively improve the E2 level and endometrial thickness on HCG injection day in patients with polycystic ovary syndrome of kidney deficiency and blood stasis type，so as to increase the rates of ovulation and pregnancy.
