目的探讨冻存时间对胚胎发育潜能的影响。方法将2013.8-2016.5我院行程序化冷冻胚胎复苏移植的胚胎按冻存时间分为三组,组1为冻存≤12个月,组2为13-60个月,组3为≥60个月,进行胚胎复苏和发育潜能的比较。结果三组胚胎存活率、完整率和继续发育、囊胚形成和优囊率均无统计学差异(P>0.05)。结论冻存时间对胚胎复苏和发育潜能并无影响。
Objective To investigate the effect of cryopreservation time on embryonic development potential. Methods The frozen embryos resuscitated from March 2013 to August 2016 in our hospital were divided into three groups according to the cryopreservation time: group 1 was frozen for ≤12 months, group 2 was 13-60 months, group 3 was ≥60 Month, compared embryonic recovery and developmental potential. Results There was no significant difference in embryo survival rate, intact rate and development between the three groups (P> 0.05). Conclusion The cryopreservation time has no effect on embryonic recovery and developmental potential.
