厚度偏薄的子宫内膜对体外受精-胚胎移植及冻融胚胎移植妊娠率的影响

摘要

探讨厚度偏薄的子宫内膜对体外受精-胚胎移植(in vitro fertilization and embryo transfer,IVF-ET)及冻融胚胎移植(freezing-thawing embryo transfer,FET)临床妊娠率的影响.方法2008年12月至2010年4月在河南省人民医院对218周期子宫内膜厚度在6 ～7.9mm之间的IVF-ET及FET患者进行回顾性分析,比较子宫内膜厚度在6～7.9mm之间的IVF-ET及FET患者的临床妊娠率有无差异.结果子宫内膜厚度在6～7.9mm之间的IVF-ET组与FET组患者的临床妊娠率分别为35.6％和50.7％,差异有统计学意义(P＜0.05).结论 子宫内膜偏薄患者FET的临床妊娠率高于IVF-ET的临床妊娠率.%Objective To compare the pregnancy rate between IVF-ET patients and FET patients both with thinner endo-metrial thickness. Methods Between Dec 2008 and Apr 2010,We made retrospective clinical analysis to 218 ovulation induction cycles of IVF-ET and FET patients with endometrial thickness of 6 - 7. 9mm, in order to compare the pregnancy rate between these IVF-ET and FET patients in Henan Provincial Peoples Hospital. Results The pregnancy rate of IVF-ET group is 35. 6% while in FET group it is 50. 7% with significant differences (P < 0. 05). Conclusion Patients with thinner endometrial have higher pregnancy rates when FET than IVF-ET treated them.
