All motion-related parameters were better for sperm in ELRS3 and ELS3 than those in other solutions, although their values were significantly lower than those of fresh sperm (n = 6, P < 0.05). Values are means ± standard deviation, and means with different letters (a, b, c, d, e, f, g) are significantly different (P < 0.05).
