摘要 目的评价高龄(≥40岁)不孕妇女体外受精助孕的临床结局。方法回顾性分析356例高龄不孕妇女共409个取卵周期的临床资料,按年龄分40岁、41岁、42岁、43岁、≥44岁5组,比较各组的一般临床资料及结局。结果高龄妇女的平均不孕年限(6.51±4.35)年,81.4%为继发性不孕。随着年龄增加,取卵周期数逐渐减少,用药时间缩短,用药量减少,获卵数减少,其中26个周期未获取卵子,41岁以上各组获卵数≤5个的比例占50%以上。共298个(72.9%)周期进行胚胎移植,移植周期妊娠率为15.4%。各年龄组取卵周期临床妊娠率分别为19.1%、9.3%、6.8%、5.1%和4.1%,妊娠率和种植率从41岁开始急速下降。45岁以上取卵25个周期,无一例妊娠。多因素logistic回归分析显示高龄妇女体外受精-胚胎移植后妊娠与年龄和移植胚胎数显著相关。结论高龄妇女行体外受精-胚胎移植的妊娠率低而流产率高,≥45岁妇女无妊娠发生,应尽量避免高龄生育。
