目的:探讨来曲唑(LE)联合FSH在多囊卵巢综合征(PCOS)患者IVF-ET或ICSI中的应用及效价分析。方法:回顾性分析接受IVF-ET/ICSI治疗的170名PCOS不孕患者,分为LE组(LE-FSH组,n=59)与对照组(GnRHa-FSH组,n=111)。比较组间促排卵、妊娠结局、...目的:探讨来曲唑(LE)联合FSH在多囊卵巢综合征(PCOS)患者IVF-ET或ICSI中的应用及效价分析。方法:回顾性分析接受IVF-ET/ICSI治疗的170名PCOS不孕患者,分为LE组(LE-FSH组,n=59)与对照组(GnRHa-FSH组,n=111)。比较组间促排卵、妊娠结局、每周期治疗费用及药物效价比。结果:LE组和对照组FSH用药天数分别为6.3±1.9 d vs 13.0±2.3、用药量为615.6±284.6 IU vs l 504.9±424.9 IU,组间比较有显著性差异(P<0.01);hCG注射日E2值分别为1 965.3±1119.7 pmol/L vs 12 660.2±7 254.2 pmol/L,获卵数分别为6.5±3.3 vs16.6±7.9,组间比较均有显著性差异(P<0.01);受精率、胚胎种植率分别为66.1%vs71.6%,25.58%vs 23.63%,临床妊娠率为49.12%vs 34.48%,组间比较无显著性差异(P>0.05);中-重度OHSS发生率分别为O%和6.89%,组间比较差异有显著性(P<0.01)。LE组每刺激周期药费(2 877±1 240元)及每妊娠周期药费(3 014±1581元)显著低于对照组(6 561±1 852元、8774±1970元)(P<0.01),治疗效价比分别为5 959元vs 30 067元。结论:LE联合促卵泡素可有效运用于PCOS患者的IVF-ET中,较传统的GnRHa-FSH促排卵相比,无OHSS的发生、费用低、效价比高,且不影响妊娠率和种植率。展开更多
