摘要 目的:比较不同年龄组长方案体外受精-胚胎移植(IVF-ET)临床、实验室指标及妊娠结局的差异。方法:回顾性分析2009年10月~2011年11月在河南省人民医院生殖医学研究所接受新鲜周期长方案降调节IVF-ET助孕治疗的患者,其中符合入选标准的共1 834周期,根据女方患者的年龄分为4组[A组(≤25岁)、B组(26~30岁)、C组(31~35岁)和D组(≥36岁)],比较不同年龄组间的不孕年限、内膜厚度、基础卵泡刺激素(FSH)、体重指数(BMI)、促性腺激素(Gn)天数、Gn总量、卵子数目、2PN数目、可利用胚胎数目、h CG日E2/成熟卵子数、移植胚胎数、孕囊数、临床妊娠率、胚胎种植率、早期流产率,分析年龄对IVF/ICSI-ET临床及实验室指标的影响。结果:4组间内膜厚度、基础FSH、BMI、Gn天数、绒毛膜促性腺激素使用日(h CG日)E2/成熟卵子数、妊娠率和宫外孕率比较差异无统计学意义(P〉0.05),但是各组间不孕年限、Gn总量差异有统计学意义,两两比较任意两组间的不孕年限、Gn总量均有统计学意义(P〈0.01);各组之间卵子数目、2PN数目、可利用胚胎数目、移植胚胎数比较差异有统计学意义(P〈0.05);而A、B、C与D组的种植率、早期流产率比较差异有统计学意义(P〈0.05)。结论:1卵巢储备功能好的高龄患者进行长方案IVF-ET助孕可以得到理想的妊娠率,因此长方案对于部分高龄患者仍然是首选。2随着年龄的增加,促排卵药物使用量增加,获卵数及可利用胚胎数减少,胚胎种植率下降,流产率增加,可见年龄通过多个方面影响IVF-ET的过程及结局。
