摘要
ICSI技术目前在辅助生殖领域已经成为一项不可或缺的常规技术,但总体上讲IVF/ICSI的成功率在30-40%左右,结果并不令人十分满意,笔者从事实验室ICSI技术5年的时间,在这几年中,随着患者数量及经验的增长,对此技术的掌握日趋稳定和成熟.通常我们会假设纺锤体的位置在第一极体附近,故我们在进行ICSI操作时会将极体置于6点或是12点的位置,然后在3点处进针,但在工作中发现似乎在6点处会获得更多的优质胚胎,于是前瞻性的将获卵数>6个的病人分半,一半将极体放在6点一半放在12点,以比较两者的受精率.卵裂率.优胚率及不同ET患者妊娠率,期待会对临床工作有一定的指导作用,从而获得更高的成功率,这无论是对患者或是对一个生殖中心来讲都是非常重要的。
The technology of ICSI has been used for a long time. In general , the pregnancy rate of this technology has been maintained at 30% ～40%. But the result is not very satisfied. In my work I found that the site of the first polar body at 6 point or at 12 point will have a different result. Then at the 6 point will lead to a higher pregnancy rate. So I divided the patients who gained more than 6 MII oocytes apart. Half of them the polar body are at 6 point and the rest at 12 point. Then compare the cleavage rate good quality embryos rate and the pregnancy rate between them.
