本文对降低氧压是否可增强人类胚胎发育进行了研究。卵巢刺激是在月经周期的第1天开始应用hMG及GnRH类似物,直至注射hCG。由盆腔超声监测。用5000～10000IU hCG注射诱导排卵。超声指导下取卵母细胞。卵母细胞的受孕以受精后16～18h出现2个前核为准(第1天)。在第2～5天时移植胚胎。为支持黄体期,在胚胎移植 This article studies whether lowering oxygen pressure can enhance human embryonic development. Ovarian stimulation begins with the administration of hMG and GnRH analogues on day 1 of the menstrual cycle until hCG is injected. Monitoring by pelvic ultrasound. Injections of 5000 ~ 10000 IU hCG induced ovulation. Take oocytes under ultrasound guidance. Oocyte pregnancy to fertilization after 16 ~ 18h appear 2 pronuclear (on the first day). Embryos were transplanted on day 2 to day 5. To support luteal phase during embryo transfer
