Objective To evaluate the clinical efficacy of Zhuyun Yangmo Formula(composed of Dioscoreae Rhizoma,Corni Fructus,Cinnamomi Cortex,Cuscutae Semen,Chuanxiong Rhizoma,Angelicae Sinensis Radix,Lycii Fructus,Rehmanniae Radix Praeparata,Polygonati Rhizoma,Asini Corii Colla,Rubi Fructus,etc.)combined with Letrozole for the treatment of patients with infertility caused by follicular maldevelopment(FM)of kidney deficiency and blood stasis syndrome type.Methods Sixty patients with FM-caused infertility of kidney deficiency and blood stasis syndrome type treated at the Reproductive Medicine Department of Qingyuan Hospital of Traditional Chinese Medicine from February 2024 to August 2024 were randomized into a control group(30 cases,treated with Letrozole alone)and an observation group(30 cases,treated with Zhuyun Yangmo Formula plus Letrozole)for three menstrual cycles.Primary outcomes of maximum diameter of preovulatory follicles and serum levels of estradiol(E2),luteinizing hormone(LH),and follicle-stimulating hormone(FSH)in the two groups were observed before and after treatment.After treatment,the pregnancy rates in the two groups were compared.Results After treatment,serum E2,LH and FSH levels in both groups were significantly increased compared to those before treatment(P＜0.05),and the observation group showed significantly greater increase than the control group,with statistically significant differences(P＜0.01).(2)After treatment,both groups showed improvement in the maximum diameter of preovulatory follicles compared to that before treatment(P＜0.05),and the observation group demonstrated significantly better improvement than the control group,with a statistically significant difference(P＜0.01).(3)After 3 menstrual cycles of treatment,the pregnancy rate in the observation group was 40.00%(12/30),significantly higher than 16.67%(5/30)in the control group,with a statistically significant difference(P＜0.05).Conclusion Zhuyun Yangmo Formula combined with Letrozole demonstrates superior efficacy in improving follicular development,elevating serum E2,LH and FSH levels,and increasing pregnancy rates in patients with FM-caused infertility of kidney deficiency and blood stasis syndrome type when compared to Letrozole monotherapy alone.

Objective To evaluate the clinical efficacy of Yishen Pojian Formula(YSPJF)combined with Letrozole in treating infertility due to ovulatory dysfunction in polycystic ovary syndrome(PCOS)patients of kidney deficiency and blood stasis type.Methods Sixty PCOS patients diagnosed as ovulatory-dysfunction-induced infertility(kidney deficiency and blood stasis type)at the Reproductive Medicine Department of Qingyuan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from February 2024 to December 2024 were randomized into an observation group and a control group using a random number table,with 30 cases in each group.The control group received Letrozole alone,while the observation group received YSPJF combined with Letrozole.Both groups were treated for three menstrual cycles and followed up for three months.The changes in traditional Chinese medicine(TCM)syndrome scores,serum levels of sex hormones[follicle-stimulating hormone(FSH),luteinizing hormone(LH),testosterone(T),and anti-Müllerian hormone(AMH)],ovarian function parameters[antral follicle count(AFC),maximum follicle diameter(FD),and endometrial thickness(EM)]in the two groups were observed.Moreover,the ovulation rate and pregnancy rate were compared.Results(1)After treatment,the TCM syndrome scores of the two groups were lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(2)After treatment,the serum FSH of the two groups was higher than that before treatment(P＜0.05),and the levels of serum LH,T,and AMH were lower than those before treatment(P＜0.05),and the increase of the serum FSH level and the decrease of the levels of serum LH,T,and AMH in the observation group were significantly superior to those in the control group,the differences being all statistically significant(P＜0.05).(3)After treatment,AFC was reduced(P＜0.05)and FD and EM were elevated(P＜0.05)in both groups compared with those before treatment,and the reduction of AFC and the elevation of FD and EM in the observation group were significantly superior to that in the control group(P＜0.05).(4)After treatment,the ovulation rate and pregnancy rate of the observation group were 90.00%(27/30)and 50.00%(15/30),respectively,which were higher than those of the control group[70.00%(21/30)and 30.00%(9/30)],and the differences were statistically significant(P＜0.05).Conclusion YSPJF combined with Letrozole exerts significant clinical efficacy for PCOS patients with infertility due to ovulatory dysfunction of kidney deficiency and blood stasis type,and the combined therapy is effective on alleviating TCM syndromes,modulating sex hormone levels,improving ovarian function,and elevating ovulation rate and pregnancy rate.
