The highest sperm parameters were obtained using 15% DMSO in ELRS3, and relatively high average values were obtained for sperm parameters using 15% DMSO in ELS3 (n = 3, P < 0.05). Values are means ± standard deviation, and means with different letters (a, b, c, d, e) are significantly different (P < 0.05).
