Sex determination was performed on the basis of detection of the Y chromosome, without examining the X chromosome. The incidence of embryos with one or more metaphase spreads was 54.5% and 85.7% in morulae and blastocysts, respectively. Successful sexing rate was achieved with a proportion of 50% for morulae and 58.3% for blastocysts in sexed embryos with metaphase spread.  aEmbryo culture  aFreezing  aGoats  aReproduction  aThawing  aCaprino  aCongelamento  aEmbrião  aReprodução  aSex diagnosis1 aTSUNODA, Y.1 aNOZAWA, E.1 aOKAMOTO, A.1 aMURAMATSU, T.  tJapanese Journal of Animal Reproductiongv. 35, n. 2, p. 97-100, 1989.
