目的在使用常规体外受精与胚胎移植(in vitro fertilization and embryo transfer,IVF-ET)方式治疗不孕症的过程中,难免会出现全部卵子不受精或受精低下的现象,但对于是否应用卵胞浆内单精子显微注射(intracytoplasmic sperm injection,ICSI)技术对未受精卵补救授精一直存在争议。目前,随着对短时受精研究的逐渐深入,早期补救ICSI的应用正成为生殖医学工作者研究的热点。因其应用后获得了理想的受精率、优质胚胎率,达到了提高妊娠率、减少周期取消率的目的 ,故其优势远远大于晚补救ICSI。
OBJECTIVE: In the process of infertility treatment by in vitro fertilization and embryo transfer (IVF-ET), it is inevitable that all oocytes will not fertilize or fertilize, but whether or not to apply oocyte cytoplasm It has been controversial that intracytoplasmic sperm injection (ICSI) technique is used to fertilize unfertilized eggs. At present, with the gradual deepening of the research on short-term fertilization, the application of early recovery ICSI is becoming a hot issue for reproductive medical workers. Because of its application to obtain the desired fertilization rate, high-quality embryo rate, to achieve the purpose of raising the pregnancy rate, reduce the cycle cancellation rate, so the advantage is far greater than late recovery ICSI.
