Resveratrol Improves Boar Sperm Quality via 5AMP-Activated Protein Kinase Activation during Cryopreservation

Figure 2

Effects of different concentrations of resveratrol on postthaw sperm lipid peroxidation (a), mitochondrial membrane potential (b), ROS level (c), GSH level (d), GPx activity (f), SOD activity (g), and catalase activity (h). Photomicrographs of the postthaw sperm stained with ROS and GSH probes, respectively (e): the red arrow indicates sperm with a high level of intracellular ROS (high green fluorescence level), the yellow arrow indicates sperm with a low intracellular ROS level (low green fluorescence level), and white arrow indicates the distribution of GSH in sperm. .
