Fig. 3From: Effect of exposure to CeO2 nanoparticles on ram spermatozoa during storage at 4 °C for 96 hoursSecondary kinematic parameters assessed by CASA of ram spermatozoa exposed to CeO2 NPs for 96 h at 4 °C. Different letters (a, b) indicate significant differences among treatments within time points (P < 0.05). Time had a significant effect on the analysed parameters (P < 0.05). Results are shown as means ± SEMBack to article page
