Means with different superscript letters on the same row are significantly different (P<0.05). † PI-/PSA-, intact plasma membrane and acrosome; PI-/PSA+, intact plasma membrane and injured acrosome; PI+/PSA-, injured plasma membrane and intact acrosome; PI+/PSA+, injured plasma membrane and acrosome. ΔΨ, mitochondrial potential. ‡ n=number of ejaculates.
