This study was carried out to determine the factors on achieving good viability of embryos biopsied fur sexing, to investigate pregnancy rate following embryo transfer(ET) with sexed embryos, and to confirm the accuracy for the calves bort following ET with sexed embryos by polymerase chain reaction(PCR). To investigate viability of Hanwoo embryos after biopsy for sexing, fresh and frozen/thawed embryos were biopsied according to different developmental day of blastocysts, different stage of blastocysts, and different biopsy grade and the embryos themselves were incubated for 2 hours in TCM199 after microsection to be evaluated morphologically for recovery as blastocyst. The results obtained were as follows : 1. The rate of oocytes cleaved in vitro and the rate of blastocyst of the cleaved oocytes were 52.5% and 21.6%, respectively. The rate of blastocyst on day 8 was 11.2%, denoting the highest rate during whole culture period posterior to in vitro fertilization(IVF) 2. After biopsy for sexing, the viability rate of blastocyst on day 7, 8 and 9 was 75.0%, 88.4%, and 100.0%, respectively and the viability of early, mid, and expanded blastocyst after biopsy was 75.0%, 88.9%, and 91.1%, respectively The viability rate of fresh and frozen/thawed embryos was 89.9%, 71.4%, respectively. And the viability of expanded, hatching, and hatched blastocyst of frozen/thawed embryos was : 75.0%, 75.0%, and 50.0%, respectively. The viability of embryos according to biopsy grade of 10∼20%, 21∼30%, and 31∼40% was 85.7%, 91.5%, and 71.4%, respectively. 3. Pregnancy rate after transfer with biopsied embryo between flesh and frozen/thawed embryos was 22.6% and 20.0%, respectively. 4. In comparison between sex by PCR method and sex of calves born after embryo transfer, the accuracy of sex deterimination was 92.3% (12/13).
