Mouse eggs (12-14%) and hamster eggs (87-94%) appear normal upon thawing after having been stored for 30 min to 25 h at -70 degrees C and -196 degrees C. While 89-98% of the normal appearing hamster eggs are capable of fertilization in vitro, only 4-13% of the mouse eggs can be fertilized. The ability of fertilized eggs to develop in culture and their viability upon transfer to pseudopregnant recipients is under investigation.
小鼠卵（12 - 14%）和仓鼠卵（87 - 94%）在-70℃和-196℃下储存30分钟至25小时后解冻时外观正常。虽然89 - 98%外观正常的仓鼠卵能够在体外受精，但只有4 - 13%的小鼠卵能够受精。正在研究受精卵在培养中的发育能力及其移植到假孕受体后的生存能力。
