Abstract： 目的 探讨体外受精-胚胎移植中移植胚胎在子宫腔中的深度对临床妊娠率的影响.方法 在腹部B超引导下测量92例胚胎移植患者的移植胚胎与宫底之间的距离,并取其距离平均数0.75 cm进行分组.组1(44例)的移植胚胎距离宫底＞0.75 cm,组2(48例)的移植胚胎距离宫底≤0.75 cm.分析两组的妊娠结局.结果 组1、组2患者的年龄分别为(32±3)和(31±4)岁,获卵数分别为(14±7)和(14±6)个,移植胚胎数分别为(2.3±0.6)和(2.2±0.5)个,两组分别比较,差异均无统计学意义(P＞0.05).组2的移植胚胎距宫底的距离平均为(0.50±0.21)cm,明显小于组1的(1.02±0.21)cm,两组比较,差异有统计学意义(P＜0.01);但组2的临床妊娠率为58.3%(28/48),显著高于组1的36.4%(16/44),两组比较,差异有统计学意义(P＜0.05).组2的胚胎植入率(33.0%)也高于组1(22.2%),但两组比较,差异无统计学意义(P＞0.05).结论 胚胎移植的深度对临床妊娠率有显著影响,移植胚胎的位置在子宫底处更有利于提高临床妊娠率.
