Fig. 7From: Effect of exposure to CeO2 nanoparticles on ram spermatozoa during storage at 4 °C for 96 hoursSperm chromatin structure assay in ram spermatozoa incubated with increasing concentrations of CeO2 NPs for 96 h. The DFI% was calculated as the ratio red fluorescent cells (single strand DNA)/total fluorescent cells [red + green (double strand DNA)]. Results are shown as mean percentages ± SEMBack to article page
