限制体外受精-胚胎移植(IVF-ET)成功率提高的原因是胚胎植入的失败。目前大多数患者通过体外受精(IVF)获得胚胎,但胚胎植入率仍为8％～13％,临床妊娠率(PR)约20％～25％,这意味着通过IVF得到的胚胎大多数植入失败。已建议用不同方法增加植入率,包括:①胚胎移植(ET)导管的改良。②ET过程中患者体位改变。③全麻下ET。④输送6个或更多胚胎。⑤共培养环境中孵育胚胎。⑥免疫球蛋白疗法。⑦纤维蛋白密
The reason for the limited success of IVF-ET is the failure of embryo implantation. At present, most patients get embryos by in vitro fertilization (IVF), but the rate of embryo implantation is still 8% ~ 13% and the clinical pregnancy rate (PR) is about 20% ~ 25%. This means that the majority of embryos obtained by IVF Into the failure. Different methods have been proposed to increase the implantation rate, including: (1) improvement of embryo transfer (ET) catheter. ② PET patient position during the change. ③ under general anesthesia ET. Transfer 6 or more embryos. ⑤ incubate embryos in co-culture environment. ⑥ immunoglobulin therapy. ⑦ fibrin dense
