The effects of sexing protocol (conventional vs. sexed), embryo type (fresh vs. frozen), developmental stage (International Embryo Transfer Society classification from compact morula, 4, to expanded hatched blastocyst, 8), quality (1–3), and breed of an embryo, as well as breed (Ayrshire vs. Holstein) and parity (heifer vs. cow) of a recipient on conception, were analyzed using binary logistic regression. In the backward stepwise elimination procedure, the nonsignificant variables (P > 0.15) were removed from the model. In the final model, sexing protocol, embryo type, developmental stage and quality of an embryo, and parity of a recipient remained. In the case of a significant difference, the magnitude and direction of the effects were indicated with an odds ratio. Calf mortality for male and female calves produced with sexed sperm was analyzed using a chi-square test. Possible differences were considered significant at P < 0.05.
