玻璃化与程序化对人早期胚胎冷冻复苏效果观察

Clinical application of vitrification of early human embryos

目的探讨玻璃化冷冻人早期胚胎的效果。方法应用玻璃化冷冻保存技术存了31例患者的105枚4。16细胞期的早期胚胎。结果对102枚冷冻胚胎进行了解冻，存活92枚，胚胎存活率为90．2％（92／102），存活胚胎均匀移植，种植18枚，种植率为19．57％（18／92），共进行了32个冷冻胚胎移植周期，获得10例妊娠，妊娠率31．25％（10／32）。结论玻璃化冷冻保存技术是一种冷冻保存人类早期胚胎的有效方法。

Objective To examine the clinical value of vitrification of human early embryos.Methods 105 embryos 4~16 cells from 31 cases were vitrified.Results Of the 102 embryos which were thawed,92 embryos survived(90.20%) and transferred.18 were implanted(19.57%).32 cycles were transfered,10cycles of which go to clinical pregnancy(31.25%).Conclusion vitrification can be an effective me thod for cryopreservation of human carly embryos.
