The objective of the study was to determine the relationship between the mRNA expression levels of sperm phospholipids hydroperoxide glutathione peroxidase (PHGPx) and heparin-binding protein (HBP), and in-vivo fertility in boars. The farrowing rate was not correlated with litter size. Sperm PHGPx mRNA expression level of the larger litter size (over 10) group (2,414.7±400.7) was high that of smaller litter size (below 8) group (1,875.8±311.2). Sperm HBP mRNA expression level was also higher in the larger litter size (2,255.9±360.8) group than the smaller litter size (2,155.4±378.0). However, significant differences were not observed. Sperm PHGPx mRNA level was correlated positively with litter size (r=0.206). Because the expression levels of PHGPx and HBP are not strongly correlated with in-vivo fertility, PHGPx and HBP can not be considered a predictive measure for fertility in boars.
