Antioxidant Effect of a Polyphenol-Rich Murtilla (Ugni molinae Turcz.) Extract and Its Effect on the Regulation of Metabolism in Refrigerated Boar Sperm

Table 3

Effect of sperm motility on sperm samples with and without oxidant stimulation. The groups were “control”—sperm samples incubated in the 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 antioxidant treatment. Significant differences are represented for each parameter evaluated independently in treatment groups. Different letters correspond to significant differences between treatments but independently of group motility parameters.
