| 摘 要： | 近10余年来，在体外受精一胚胎移植（IVF-ET）周期中应用促性腺激素释放激素激动剂（GnRH-a）进行控制性卵巢刺激（COS）已成为普遍采用的方法，其主要原因是GnRH-a可以促进卵巢内多个卵泡同步发育和成熟，抑制内源性黄体生成素（LH）峰，阻遏卵泡过早黄素化及卵子早熟。由于GnRH-a在IVF-ET进行降调节COS中的应用不同，可将COS方案分为长方案和短方案。第一段]

| Abstract: | To investigate the effects of the down-regulation on quality of oocyte.The protocols,age,down-regulation days before Gn and the level of LH on the day of hCG injection are not significantly related to the rate of normal fertilization and cleavage.The age between 25-35 years old and LH≤5 IU/L on the day of hCG injection,have higher rate of good-quality embryo,embryo implantation and pregrancy.The embryo's aneuploid rate is higher when the age raise up.The number of retrieval oocyte don't affect the embryo's aneuploid rate.The way of insemination and control ovarian stimulation protocols affect the embryo's aneuploid rate. |
