This study was carried out to investigate the survival rate in vitro culture after frozen-thawed to used DMSO(dimethyl sulfoxide), glycerol and ethylene glycol of cryoprotective agents at the zona pellucida removed and encased into alien bisected embryo of the mouse early embryos. The results obtained from this study were as follows : 1. The survival rate of in vitro culture after frozen-thawed to used cryoprotective agents of three kinds at the zona pellucida removed bisected morula was 46.6%, 35.8% and 27.3%, total or mean were 36.6%, respectively. 2. The survival rate of in vitro culture after frozen-thawed to used cryoprotective agents of three kinds at the encased into alien bisected morula was 70.6%, 65.3% and 66.4%, total or mean were 67.4%, respectively. 3. The survival rate of in vitro culture after frozen-thawed to used cryoprotective agents of three kinds at the zona pellucida removed bisected blastocysts was 50.4%, 36.7% and 30.4%, total of mean were 39.2%, respectively. 4. The survival rate of in vitro culture after frozen-thawed to used cryoprotective agents of three kinds at the encased into alien bisected blastocysts was 71.1%, 66.7% and 63.9%, total or mean were 67.2%, respectively.
