文摘目的探讨促性腺激素激动剂(GnRH-a)联合小剂量人绒毛膜促性腺激素(hCG)诱发排卵对卵巢高反应患者体外受精-胚胎移植的临床结局影响。方法回顾性分析2016年12月至2017年12月在南京医科大学附属妇产医院本中心采取GnRH拮抗剂方案进行控制性超促排卵,行体外受精/卵胞浆内单精子注射(IVF/ICSI)助孕的546例患者的临床资料,将因卵巢高反应分别使用GnRH-a联合5000 U hCG促排卵(hCG大剂量组,n=159)及GnRH-a联合2000 U hCG促排卵(hCG小剂量组,n=212)的患者作为研究组,同期采用标准的hCG 10000 U促排卵的患者作为对照组(n=175),比较各组患者的治疗结局。结果三组患者促性腺激素(Gn)启动剂量及用药时间比较,差异均无统计学意义(P>0.05)。hCG大剂量组患者hCG促排卵日血清雌二醇(E2)水平[(17513.52±4846.85)pmol/L]及hCG小剂量组患者[(20384.11±7754.78)pmol/L]显著高于对照组患者[(16678.67±3826.79)pmol/L](P=0.000)。两研究组的获卵数、2PN数、胚胎数、优胚数及优胚率方案高于对照组(P<0.05),同时hCG大剂量组优胚率均高于hCG小剂量组(P<0.05)。hCG大剂量组、小剂量组与对照组三组间卵巢过度刺激综合征(OHSS)率(1.3%、0.5%、2.9%)发生率比较,差异无统计学意义(P>0.05)。结论对于GnRH拮抗剂方案的高反应患者,采用减量联合促排卵方案,可提高优胚率及可移植胚胎数,不增加OHSS发生率。
