Antioxidant effect of MT-Ex. (a) Antioxidant capacity of MT-Ex on peroxides and superoxide anion production. (b) Effect of MT-Ex on lipid peroxidation. In both analyses: “control”—sperm samples incubated in MR-A semen extender; “oxidant”—sperm samples treated with oxidant agent; “MT-Ex”—sperm samples treated with 0.0315 μgGAE mL-1 as antioxidant treatment; and “MT-Ex + oxidant”—sperm samples coincubated with oxidant agent and 0.315 μgGAE mL-1 as antioxidant treatment. The oxidant agents were H2O2 and FeSO4 to produce O2-/perox and lipid peroxidation, respectively. Differences observed were and with respect to the “oxidant” group.
