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

<div>Analysis of metabolic parameters in sperm samples treated with MT-Ex. (a) Effect of MT-Ex on mitochondrial membrane potential. The data shown represent the cell count with normal potential measured by the JC-1 probe. (b) Succinate dehydrogenase activity evaluated by MTT assay. (c) Determination of ATP content. 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 <i>μ</i>gGAE mL<sup>-1</sup> as antioxidant treatment, and “MT-Ex + oxidant”—sperm samples coincubated with oxidant agent and 0.315 <i>μ</i>gGAE mL<sup>-1</sup> as antioxidant treatment. Significant differences are represented between control and groups. <span class="nowrap"><svg height="10.7395pt" id="M108" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162
