摘要
目的 探索在拮抗剂方案中添加来曲唑对符合波塞冬分类标准"非预期低预后"人群促排结局的影响.方法 本研究回顾性分析2017年1月至2019年12月期间就诊于河南省人民医院生殖中心,满足波塞冬分类标准非预期低预后患者的体外受精/卵胞浆内单精子注射(in vitro fertilization/intracytoplasmic sperm injection,IVF/ICSI)资料共188周期,根据有无在拮抗剂方案中联合应用来曲唑进行分组,拮抗剂方案联合应用来曲唑者为观察组(n=74),未用来曲唑者为对照组(n=114),比较两组患者的一般资料、促排卵结局和妊娠结局.结果 两组患者的基础资料未见明显差异(P＞0.05);观察组的促性腺激素(gonadotropin,Gn)用量显著低于对照组[(1 896.40±701.47)vs(2 032.98±760.73),P＜0.05];观察组的平均获卵数[(9.27±4.32)vs(6.97±3.90),P＜0.05]、MII卵数[(7.56±3.82)vs(6.02±3.32),P＜0.05]及优质胚胎率(28.89％ vs 20.75％,P＜0.05)显著高于对照组;两组间中重度卵巢过度刺激综合征发生率、双原核数、D3可利用胚胎数、无可移植胚胎周期取消率、临床妊娠率、早期流产率、活产率比较均无明显差异(P＞0.05).结论 来曲唑联合应用拮抗剂方案用于波塞冬标准非预期低预后患者,可增加平均获卵数和MII卵数,提高优质胚胎率,减少Gn用量,但对新鲜移植周期妊娠结局可能有不利影响.
Abstract
Objective To explore the effect of adding letrozole to an antagonist regimen on the outcome of ovulation in-duction in a population meeting the classification criteria of Poseidon for"unexpected low prognosis".Methods This study retrospectively analyzed the in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)data of patients who visited the Reproductive Center of Henan Provincial People's Hospital from January 2017 to December 2019 and met the Poseidon classification criteria for unexpected low prognosis for a total of 188 cycles.The patients were divided into ob-servation group(n=74)treated with antagonist regimen combined with letrozole and control group(n=114)not treated with letrozole according to the presence or absence of letrozole in the antagonist regimen.The general data,ovulation in-duction outcomes and pregnancy outcomes were compared between the two groups.Results No significant difference was observed in the basic data between the two groups(P＞0.05);Gn consumption in the observation group was significant-ly lower than that of the control group[(1 896.40±701.47)vs(2 032.98±760.73),P＜0.05];the mean number of oocytes retrieved[(9.27±4.32)vs(6.97±3.90),P＜0.05],number of metaphase II(MII)[(7.56±3.82)vs(6.02±3.32),P＜0.05],and high-quality embryo rate(28.89％ vs 20.75％,P＜0.05)in the observation group were significantly higher than those of the control group;there were no significant differences in the incidence of moderate to severe ovarian hyperstimulation syndrome,the number of 2 pronuclear,the number of D3 available embryos,the can-cellation rate of cycles without transferable embryos,the clinical pregnancy rate,the early abortion rate,and the live birth rate between the two groups(P＞0.05).Conclusion Letrozole combined with antagonist regimen in patients with unexpected low prognosis of Poseidon criteria can increase the average number of oocytes retrieved and MII eggs,in-crease the rate of high-quality embryos,and reduce the dosage of Gn,but it may adversely affect pregnancy outcomes in fresh transplant cycles.
