Abstract
Porcine sperm chromosome karyotypes were obtained from two boars following heterologous in vitro fertilization (IVF) of zona-free hamster ova with ionophore-capacitated porcine spermatozoa. The karyotype yield per inseminated ovum was 9.3% in = 1658), and there was no significant deviation from the expected 1 : 1 sex ratio (p > 0.5). Cytogenetic analysis revealed hyperhaploid (2.5% and hypohaploid spermatozoa (1.9% Spermatozoa with structural chromosome aberrations constituted 7.1% of the analyzed karyotypes, and these were predominantly chromosomal breaks, although acentric fragments were also found (2.6%
