RESUMO
Objective:To observe the effect of Zikun decoction (ZKD) in treatment of Yin deficiency and blood dryness in delayed menorrhea due to decreasing ovarian reservation．Method:A total of 60 cases were randomly divided into two groups．The observation group was given ZKD orally，and the control group was treated with complex packing estradiol tablets/estradiol and dydrogestero for three months．The control group began to take medicine on the first day of menstruation for 28 days, while the observation group began to take medicine on the fifth day of menstruation, and stopped taking medicine on the first day of the next menstruation. Three menstrual cycles were followed up. The clinical syndrome scores, follicle-stimulating hormone (FSH), luteinizing hormone (LH), inhibin B (INHB), FSH/LH, Estradiol (E2), anti-müllerian hormone (AMH), and antral follicle count (AFC) scores of the patients before and after treatment were compared.Result:After treatment, there was no significant difference in clinical efficiency between observation group and control group, but the traditional Chinese medicine syndrome score of observation group was significantly reduced (P<0.05), observation group and control group had the same curative effect in improvement of FSH, FSH/LH, AMH and AFC (P<0.05), but ZKD was better than complex packing estradiol tablets/estradiol and dydrogestero in improvement of INHB.Conclusion:ZKD has a good treatment effect in the treatment of DOR. It can effectively improve patients' sex hormone levels, increase antral follicle count, improve the ovarian reserve function and promote menstruation.
