We have confirmed more rapid development of male compared with female in vitro-cultured bovine embryos during the first 7 d after in vitro fertilization. The male-to-female sex ratio of expanded blastocysts after 10 d of in vitro culture was 1.37:1.00, which was significantly different from the expected 1:1 ratio, but no deviation from a 1:1 ratio was observed for male and female expanded blastocysts derived from culture of bovine embryos in the sheep oviduct (1.11:1.00). When embryos that developed only to the morula stage were analyzed for sex, a greater number of female than male bovine embryos was observed from in vitro culture but not after culture in the sheep oviduct. Possible causes of these sex-related differences in development of cultured bovine embryos are discussed.
