文摘Objective:To evalvate efficacy of Qizi Yusi Pills(QYP),a Chinese medicine compound preparation,on in vitro fertilization-embryo transfer(IVF-ET)in women of advanced reproductive age.Methods:This multicenter,randomized,double-blind,placebo-controlled trial was conducted from June 2018 to October2019.A total of 124 patients were randomly allocated to either the QYP group or the placebo group using a stratified block randomization design,with 62 patients in each group.All patients completed controlled ovarian stimulation using a standard gonadotropin-releasing hormone agonist(GnRH-a)long protocol.As the QYP group,QYP was administered while the control group received placebo.QYP and placebo were administered for a total of 24 to 30 days from the day of GnRH-a pituitary downregulation to transvaginal oocyte retrieval.Both medications were taken orally at doses of 10 g three times each day.The primary outcome was cumulative pregnancy rate,and the secondary outcomes were periodic medication,follicular status,serum hormone and endometrial receptivity.Follow-up continued until 4 weeks after delivery.Maternal and neonatal complications,such as gestational diabetes,were also observed.Results:Overall,119 patients completed the study,60 in the QYP group and 59 in the placebo group.Per protocol(PP)analysis revealed that 6-month cumulative pregnancy rate in the QYP group was significantly higher than that in the placebo group[43.33%(26/60)vs.25.42%(15/59),P=0.040].Additionally,more oocytes were retrieved from the QYP group than those from the placebo group(8.95±3.12 vs.7.85±1.91,P=0.022).Moreover,the endometrial thickness of HCG day in the QYP group was significantly higher than that in the placebo group(11.78±2.27 mm vs.10.68±2.07 mm,P=0.012).Maternal and neonatal complications between the two groups were not significantly different(P>0.05).Intention-to-treat analysis was in line with PP results.Conclusions:QYP can enhance ovarian reserve capacity and ovarian response,and possibly promote endometrial receptivity.QYP effectively improves cumulative pregnancy rates in older patients(≥35 years)undergoing IVF-ET.(Registration No.ChiCTR1800014427).

文摘Objective:Congenital uterine anomalies are common;however,their effects on artificial insemination by husband(AIH)and the period during which AIH is converted to in vitro fertilization(IVF)are unclear.We examined the influence of uterine malformations on reproductive outcomes following AIH and the optimum number of AIH cycles before resorting to IVF-embryo transfer(IVF-ET).Methods:We retrospectively recruited 168 patients with uterine malformations(anomalous group)undergoing AIH between January 2011 and December 2016.Meanwhile,168 patients with infertility but with normal uteri(normal group)were matched as controls according to age.Results:The clinical pregnancy rate was similar in both groups(12.4%vs.12.3%,P=0.950);the cancellation(21.6%vs.4.4%,P<0.001),early pregnancy loss(35.7%vs.11.4%,P=0.032),and preterm birth rates(21.4%vs.2.9%,P=0.038)were higher in the anomalous group,resulting in lower term birth(32.1%vs.74.3%,P=0.001)and live birth rates(50.0%vs.77.1%,P=0.034).After two AIH cycles,the clinical pregnancy rate was lower(3.6%vs.23.1%,P=0.037)among women with uterine anomalies than among those with normal uteri.There was no difference in the pregnancy rates(52.5%vs.53.7%,P=0.908)between the two groups of patients with unsuccessful AIH who then underwent IVF-ET.Conclusions:IVF-ET can be performed immediately after two unsuccessful AIH cycles in patients with uterine malformations.In patients undergoing AIH or IVF,uterine malformations increase the risk of adverse obstetric outcomes.
