摘要目的 探讨无创性内膜刺激胚胎移植(stimulation of endometrium embryo transfer,SEET)技术在冻融胚胎移植(frozen-thawed embryo transfer,FET)周期中对妊娠结局的影响.方法 回顾性分析2016年3月-2017年2月在本中心进行体外受精-胚胎移植(IVF-ET)并首次行单囊胚FET的不孕症患者的临床资料,按移植方式分组:A组(实验组)57个周期,FET时采用SEET技术;B组(对照组)56个周期,FET时采用传统囊胚移植技术.结果 A组采用SEET技术后的胚胎种植率(64.9％)和临床妊娠率(64.9％)显著高于B组(44.6％,44.6％).结论 SEET技术可以显著提高临床妊娠率,为改善IVF结局提供了一种新的移植策略.

abstractsObjective To study the effect of non-invasive stimulation of endometrium embryo transfer (SEET) on pregnancy outcome in the frozen-thawed embryo transfer (FET) cycles.Methods Retrospective analysis was performed in the patients with their first in vitro fertilization (IVF) and FET cycle in our reproductive medicine center from March 2016 to February 2017.All the patients were undergoing single FET,and based on the procedure of transfer,they were divided into two categories:group A (SEET group) included 57 cycles,which used SEET during FET;group B (control group) included 56 cycles,which used conventional blastocyst transfer during FET.Results The implantation rate and clinical pregnancy rate in the SEET group (64.9％,64.9％) were statistically significantly higher than those in control group (44.6％,44.6％).Conclusion During FET cycles,SEET could increase the clinical pregnancy rate,which may provide a new strategy of embryo transfer for IVF outcome improvement.
