| 摘 要： | 目的:探讨IVF-ET周期中不同胚胎选择体系对妊娠结局的影响。方法:将530个IVF-ET周期随机分为3组,按不同的胚胎选择方法选择胚胎进行移植。A组:228个移植周期,根据d3胚胎常规评分方法选择胚胎;B组:140个移植周期,根据d3胚胎常规评分结合原核评分选择胚胎;C组:162个移植周期,根据d3胚胎常规评分结合胚胎早期分裂选择胚胎。将C组进一步分为移植胚胎中有早裂胚胎和无早裂胚胎二组。比较各组的临床妊娠率和单胚着床率。结果:B组的临床妊娠率和单胚种植率为37.86%和21.77%,与A组(33.33%和20.56%)比均无统计学差异(P>0.05);而C组(45.06%和30.88%)均显著高于A组(P<0.05);C组移植胚胎中有早裂胚胎者的临床妊娠率和单胚着床率为55.68%和38.38%,分别显著高于移植胚胎中不含早裂胚胎者(32.43%和21.94%)(P<0.05)。结论:d3胚胎常规评分结合胚胎早期分裂选择的胚胎移植,可以提高IVF-ET周期的临床妊娠率和单胚着床率。 |

| Abstract: | Objective:To evaluate the influence of different embryo-selective systems on the clinical outcome in IVF/ICSI cycles. Methods:A total of 530 IVF/ICSI cycles were assigned into 3 groups randomly:transferred embryos were chosen by the d3 quanlity in group A,pronuclear grade and early-cleaving were added to the selecting system in group B and group C,separately. The clinical outcome of each group was compared,and cycles with or without early-cleaving embryos were also analysed. Results:The clinical pregnancy r... |
