目的 探讨接受冻胚移植(FET)患者移植前1日雌二醇(E2)浓度变化对妊娠结局的影响.方法 选取360例接受FET助孕治疗且内膜准备方案为自然周期方案(NC)及激素替代周期方案(HRT)的不孕患者作为研究对象,根据移植前1日E2浓度的变化分为3组.A组244例,移植前1日E2≥100 pg/mL;B组48例,移植前1日E2<100 pg/mL;C组68例,移植前1日E2<100pg/mL+注射人绒毛膜促性腺激素(HCG).随访并分析3组患者的一般资料、临床特征、妊娠结局.结果 3组患者的一般资料差异无统计学意义(P>0.05),妊娠结局中,3组患者的生化妊娠率分别为3.28%、2.08%、4.41%;早期流产率分别为18.02%、22.22%、13.79%;多胎妊娠率分别为10.81%、22.22%、3.44%,差异均无统计学意义(P>0.05).3组患者的临床妊娠率分别为45.49%、18.75%、42.65%;活产率分别为 37.29%、14.58%、36.76%,差异有统计学意义(P<0.05).NC 方案中,3组患者的临床妊娠率分别为49.18%、19.05%、47.73%,差异有统计学意义(P<0.05).HRT方案中,3组患者的临床妊娠率分别为44.26%、18.52%、33.33%,差异有统计学意义(P<0.05).结论 移植前1日雌二醇(E2)浓度变化与临床妊娠率呈显著相关,对于接受FET且E2<100 pg/mL的患者,内膜准备时添加小剂量的人绒毛膜促性腺激素(HCG)可以提高临床妊娠率,FET内膜准备时NC方案和HRT方案对妊娠结局没有影响.
Abstract
Objective To explore the impact of changes in estradiol(E2)concentration on pregnancy outcomes in patients un-dergoing frozen embryo transfer(FET)on the first day before transplantation.Methods A total of 360 infertile patients who received FET assisted pregnancy treatment with natural cycle(NC)and hormone replacement cycle(HRT)endometrial preparation regimens were se-lected as the study subjects.They were divided into three groups based on the changes in E2 concentration on the day before transplanta-tion.There were 244 cases in group A,with E2≥100 pg/mL on the day before transplantation,48 cases in group B,with E2<100 pg/mL on the day before transplantation,and 68 cases in group C,with E2<100 pg/mL+injection of human chorionic gonadotropin(HCG)on the day before transplantation.The general information,clinical characteristics,and pregnancy outcomes of three groups of patients were fol-lowed up and analyzed.Results There was no statistically significant difference in general information among the three groups(P>0.05).In terms of pregnancy outcomes,the biochemical pregnancy rates of the three groups were 3.28%,2.08%,and 4.41%,respec-tively.The early miscarriage rates were 18.02%,22.22%and 13.79%,respectively.The multiple pregnancy rates were 10.81%,22.22%,and 3.44%,respectively,and the differences were not statistically significant(P>0.05).The clinical pregnancy rates of the three groups were 45.49%,18.75%,and 42.65%,respectively.The live birth rates were 37.29%,14.58%,and 36.76%,respective-ly,with statistically significant differences(P<0.05).In the NC protocol,the clinical pregnancy rates of the three groups were 49.18%,19.05%,and 47.73%,respectively,with statistically significant differences(P<0.05).In the HRT regimen,the clinical pregnancy rates of the three groups of patients were 44.26%,18.52%,and 33.33%,respectively,with statistically significant differences(P<0.05).Conclusion The change in estrogen(E2)concentration on the day before transplantation is significantly correlated with clinical pregnancy rate.For patients receiving FET with E2<100 pg/mL,adding a small dose of human chorionic gonadotropin(HCG)during endometrial preparation can improve clinical pregnancy rate.NC and HRT regimens during FET endometrial preparation have no effect on pregnancy outcome.
