Lipid peroxidation levels are significantly decreased in WT as well as Pmca4−/− sperm following administration of the walnut-enriched diet. Lipid peroxidation levels were assessed via a Thiobarbituric Acid Reactive Substances Assay (TBARS) assay. Mean malondialdehyde [MDA (μM)] levels in WT and Pmca4−/− sperm from control and animals treated with a diet (enriched in PUFAs and antioxidants) for 9–11 weeks are shown. Lipid peroxidation levels decrease in both WT and nulls following diet implementation. (Two-way ANOVA: *p < 0.05, N = 6, mean ± SEM).
