Clinical trial of dydrogesterone combined with granulocyte colony-stimulating factor in the treatment of patients with thin endometrial infertility
Objective To explore the effects of dydrogesterone combined with granulocyte colony-stimulating factor(G-CSF)on blood flow parameters and sex hormone levels in patients with thin endometrial(TE)infertility.Methods TE infertility patients were randomly divided into control group and treatment group.All patients were treated with freezing-thawing embryo transfer.The control group was treated with desdrogesterone after ovulation monitoring by vaginal ultrasound,10 mg each time,bid,and stopped until the 14th day after ovulation.In treatment group,G-CSF was given on the basis of control group,and the endometrial thickness and hemodynamic parameters were monitored by vaginal ultrasound 3 days later,and then embryo transfer was performed.Blood flow parameters,ultrasound parameters,endometrial morphology,sex hormone levels[follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),progesterone(P)]and pregnancy status were compared between the two groups.Results There were 49 cases in treatment group and 49 cases in control group.After treatment,endometrial thickness in treatment group and control group were(9.59±1.35)and(7.89±1.14)mm;follicle diameter were(19.35±1.58)and(17.75±1.42)mm;uterine volume were(92.68±7.85)and(85.69±6.74)cm3;PI were 1.29±0.27 and 1.74±0.32;RI were 0.32±0.09 and 0.50±0.11;peak systolic/end-diastolic velocity(S/D)were 2.03±0.28 and 2.21±0.25;P were(45.98±5.75)and(39.15±5.78)nmol·L-1;E2 were(462.58±58.42)and(339.45±45.97)pg·mL-1;FSH were(12.18±2.58)and(9.42±1.42)U·L-1;LH were(29.42±4.18)and(22.25±3.40)U·L-1;there were statistically significant differences between the two groups(all P＜0.05).The clinical pregnancy rate(51.02％)and implantation rate(57.14％)in treatment group were higher than those in control group(30.61％and 36.73％),and the differences were statistically significant(all P＜0.05).Conclusion Dydrogesterone combined with G-CSF can improve blood flow parameters,endometrial thickness and sex hormone levels in TE infertility patients,and help to increase the embryo implantation rate.
