1、适当的降调节在体外受精-胚胎移植长方案治疗中的价值何畏,俞炽阳,王凤英,李红梅,龙玲,曲宗银,邓丽,姚春丽(第三军医大学西南医院妇产科生殖中心,重庆400032)摘要:目的探讨使用促性腺激素释放激素激动剂降调节在体外受精-胚胎移植治疗中的意义。方法回顾分析我中心2008年1~12月185位例因不孕不育接受体外受精-胚胎移植助孕的长方案治疗周期共187个。根据促性腺激素使用前患者是否达到降调标准,分为达标组(A组,n=95)与未达标组(B组,n=92)。分析比较两组患者年龄、使用GnRH-a和Gn剂量、获卵数、成熟卵数、受精率、优质胚胎率、临床妊娠率等之间的差异。结果A
2、、B两组的临床妊娠率分别为48.94%和32.61%,达标组A组显著高于未达标组B组(P<0.05);继续妊娠的观察中,二者的流产率无明显差别;达标组A组使用GnRH-a和Gn的剂量略大于未达标组B组,但两组间的差异无统计学意义。实验室资料显示两组的获卵数、MⅡ卵数以及受精率均较接近,均无明显差异(P>0.05);而在优质胚胎获得率的对比中,达标组A组(43.70%)明显高于未达标组B组(31.80%)(P<0.05)。结论在体外受精-胚胎移植的长方案治疗中,垂体降调节达标者的临床妊娠率高于未达标者。可见降调节是否充分和适当对助孕治疗的结局有重要意义。本中心现行的降调
