小剂量长效GnRH-a黄体中期卵巢刺激方案的临床效果分析

目的:探讨小剂量长效促性腺激素释放激素激动剂(GnRH-a)黄体中期控制性卵巢刺激方案临床效果及对体外受精-胚胎移植(IVF-ET)的影响。方法:回顾性分析行IVF-ET治疗的患者资料,按照黄体中期使用的GnRH-a剂量不同分为两组,1组GnRH-a用量为1.25mg(1/3支),共154周期;2组GnRH-a用量为0.94mg(1/4支),共100周期,比较临床效果和IVF-ET结局。结果:两组对象卵巢刺激的时间及用药量比较差异无统计学意义(P>0.05),启动日及人绒毛膜促性腺激素(hCG)日卵泡?素(FSH)、黄体生成素(LH)、雌激素(E2)、孕激素(P)等水平两组差异无统计学意义(P>0.05)。两组启动日未达降调节标准比率差异有统计学意义(3.25%与10.00%,P<0.05),hCG日LH>5.0U/L的比率差异有统计学意义(1.95%与9.00%,P<0.05)。两组卵巢过度刺激综合征发生率差异无统计学意义(3.90%与7.00%,P>0.05);获卵数、优质胚胎率两组差异无统计学意义(P>0.05),1组的正常受精率较2组高,差异有统计学意义(P<0.05),移植周期妊娠率差异无统计学意义(57.33%与46.88%,P>0.05);胚胎种植率、早期流产率两组差异均无统计学意义(P>0.05)。结论:1.25mg与0.94mg剂量GnRH-a在黄体中期控制性卵巢刺激方案中,可以得到几乎相同妊娠结局,对于卵巢正常反应的人群,1.25mg剂量的效果更好些。

Comparison of clinical effects of different low-dose long-acting gonadotropin-releasing hormone agonist in long protocol of controlled ovarian stimulation

Objective:To explore the influence and clinical effects of the low-dose long-acting gonadotropin-releasing hormone agonist(GnRH-a)in the long protocol of controlled ovarian stimulation for in vitro fertilization and embryo transfer(IVF-ET).Methods:The clinical data of IVF-ET treatment were analyzed.According to the doses of GnRH-a used at mid-luteal phase,the women were divided into two groups:group 1(1.25mg,a total of 154 cycles)and group 2(0.94mg,a total of 100 cycles).The clinical effects of controlled o...
