| 摘 要： | 目的探讨体外受精移植优质胚胎数量对临床妊娠率和多胎率的影响。方法对患者年龄<35岁的829个体外受精-胚胎移植(IVF-ET)及卵胞浆内单精子注射(ICSI)周期,按移植优质胚胎数量分为四组:0组移植0个优质胚胎,1组移植1个优质胚胎,2组移植2个优质胚胎,3组移植3个优质胚胎,分析各组临床妊娠率和多胎率的差异。结果2、3组与0、1组比较,种植率和临床妊娠率显著升高(P<0.05),但2组与3组之间的种植率和临床妊娠率无显著性差异。3组的多胎率较0、1、2组显著升高(P<0.05),尤其是三胎率较2组显著升高(P<0.05)。结论移植优质胚胎数量影响种植率、临床妊娠率和多胎率。对于<35岁的患者,为获得满意的临床妊娠率并尽可能预防多胎,尤其是三胎的发生,移植2个优质胚胎已足够。

| Abstract: | Objectives: To investigate the influence of number of high-quality embryos transferred on clinical pregnancy rate and multiple pregnancy rate in in vitro fertilization/embryo transfer(IVF-ET).Methods: A total of 829 IVF-ET and ICSI cycles of the patients aged <35 years were analyzed retrospectively.Cases were divided into 4 groups according to the number of high-quality embryos transferred(Group 0: no high-quality embryo transferred;Group 1: one transferred;Group 2: two transferred;Group 3: three transferre... |
