This study was done to verify factors affecting viability after cryopreservation and pregnancy rate after frozen-thawed embryo transfer into uterus. Embryos were cryopreserved slow freezing and slow thawing and used DMSO as cryoprotectant. The results were to follows. 1. Viability of frozen-thawed embryos were 75.5% (94/105), which compared with viability of embryos according to cell stage, $2{\sim}5$ cell was 68.4% and $6{\sim}16$ cell 80.4% were significant differences (p<0.05). 2. No significant difference in duration of cryopreservation on effects affecting pregnancy rate was observed. 3. Number of embryo transfered into uterus was significant differences (p<0.05). 4. Four pregnancies resulted following replacement of 35 frozen-thawed.
