Mean ± standard deviation (SD) of the A percentage of chromomycin A3 (CMA3)-positive sperm (CMA3+ sperm) and B CMA3 fluorescence intensity of the CMA3-positive sperm population (CMA3+ fluorescence intensity [arbitrary units; AU]) of viable, non-viable and total sperm populations at 0 h and 4 h post-thaw. Samples that have different letters (a, b) indicate that statistically significant differences (P < 0.05) were found between sperm populations (viable, non-viable and total sperm) within a given time point (0 h and 4 h post-thaw), whereas different numbers (1, 2) indicate statistically significant differences (P < 0.05) between time points (0 h and 4 h post-thaw) within a given sperm population (viable, non-viable and total sperm)
