Abstract： Objective： To observe the clinical effect of Xingqi Huoxue Decoction combined with estrogen and progesterone sequential therapy on scanty menstruation after induced abortion of qi stagnation and blood stasis type. Methods：A total of 350 cases of patients with scanty menstruation after induced abortion of qi stagnation and blood stasis type were divided into the study group and the control group according to the random number table method，with 175 cases in each group. The control group was treated with estrogen and progesterone sequential therapy，and the study group was treated with Xingqi Huoxue Decoction combined with estrogen and progesterone sequential therapy. Both groups were continuously treated for 3 menstrual cycles. Before and after treatment， traditional Chinese medicine syndrome scores were evaluated； menstrual volume and endometrial thickness were recorded； sexual hormone indicators [follicle stimulating hormone (FSH)， luteinizing hormone (LH)， estradiol (E2)， and prolactin (PRL)] were measured. The incidence of adverse drug reactions during the treatment was counted. Clinical effects were compared between the two groups. The recurrence rate during the 6-month follow-up after treatment was counted. Results：After treatment for 3 menstrual cycles，the total effective rate in the study group was higher than that in the control group (P＜0.05). Menstrual volume and endometrial thickness in the two groups were increased when compared with those before treatment (P＜0.05)； menstrual volume and endometrial thickness in the study group were more than those in the control group， differences being significant (P＜0.05). The contents of FSH，LH，and E2 in serum in the two groups were increased when compared with those before treatment， and PRL contents in serum were decreased， differences being significant (P＜0.05). The contents of FSH，LH，and E2 in serum in the study group were higher than those in the control group，and PRL content in serum in the study group was lower than that in the control group，differences being significant (P＜0.05). There was no significant difference being found in the comparison of incidence of adverse reactions between the two groups (P＞0.05). The recurrence rate in the study group was lower than that in the control group (P＜0.05). Conclusion：For patients with scanty menstruation after induced abortion of qi stagnation and blood stasis type， Xingqi Huoxue Decoction combined with estrogen and progesterone sequential therapy can enhance the clinical effects， promote endometrial repair and regeneration， regulate sex hormone levels， improve menstrual disorders， and reduce recurrence.
