These studies were carried out to examine the sex of preimplantation mouse embryo. For the investigation of sex-ration of mouse embryos, morula and blastocysts stage embryos treated with H-Y antiserum (10%, v/v) and FITC anti-mouse-IgG were divided into the positive and negative embryos. Positive and negative identified embryos were observed the viability according to the in vitro cultured and the sex ratio was also investigated by chromosomal analysis. The results obtained in these studies were summarized as follows: 1. Two hundred sixty-seven recovered embryos of morula or blastocyst stage were incubated in medium containing H-Y antiserum and FITC anti-mouse-IgG. Positively or negatively identified embryos were 139 and 128. This trend indicated the approximal sex ratio was 1:1. 2. Sex ratio was measured using the embryos treated with indirect immunofluorescence assay to examine the relationship between embryo developmental stage and sex ratio. Sex ratio of morula stage embryos was 45.2% positive and 54.8% negative, on the other hand, the ratio switched to 56.4% positive and 43.6% negative embryo in blastocyst stage. 3. Fourty-seven positive and 57 negative embryos were obtained out of 104 morula stage embryos treated with indirect immunofluorescence assay. Survived positive or negative embryos during in vitro culture were 42 and 49, respectively out of 47 and 57 embryos. 4. The numbers of negative and positive embryos were 171 and 92 out of 163 blastocyst embryos which were incubated in the medium containing H-Y antiserum and FITC anti-mouse-IgG. The result of karyotype test showed the successful rate of sexing embryo is positive and negative embryos was63.0% (58/92) and 62.0% (44/71). The final female to male ratio within 58 positive embryos was 22.7:77.6, and the ratio of the 44 negative embryos was 77.3:22.7.
