摘要 目的探讨注射绒毛膜促性腺激素(HCG)后不同时间取卵对体外受精-胚胎移植(IVF-ET)周期妊娠结局的影响。方法按照注射HCG后的不同取卵时间分组,A组(n=41)34~<36 h取卵,B组(n=589)36~38 h取卵。以行常规IVF-ET或卵胞浆内单精子注射的辅助生育治疗周期为研究对象,以获卵率、受精率、临床妊娠率、早期流产率等为观察指标,回顾分析注射HCG后不同时间取卵对IVF-ET周期妊娠结局的影响。结果 A组获卵率、受精率均低于B组,分别为65.8%(321/488)和71.5%(6 318/8 833)、80.4%(258/321)和82.8%(5 233/6 318),差异均有统计学意义(P<0.05)。A组临床妊娠率低于B组,分别为29.7%(11/37)、40.5%(223/551);而其早期流产率则高于B组,分别为18.2%(2/11)、4.9%(11/223),差异均有统计学意义(P<0.05)。结论注射HCG后36~38 h取卵或能改善IVF-ET周期的妊娠结局。
