From: New approach to assess sperm DNA fragmentation dynamics: Fine-tuning mathematical models
Effect of centrifugation (UDC, SW, and SLC) on the percentage of sperm DNA fragmentation (sDF, %) of frozen-thawed donkey sperm for 24 h of incubation at 37 °C. Values are expressed as means (bars) ± SEM (error bars). Different superscripts letters indicate significant differences (P < 0.05). UDC = Uncentrifuged diluted control; SW = Sperm washing; SLC = Single Layer Centrifugation; T0, T3, T6, T24 = Incubation for 0, 3, 6, 24 h at 37 °C
