In this study, we used flow a cytometric assay to evaluate plasma membrane integrity and mitochondrial activity in post-thawed sperm that was supplemented with ginsenoside-$Rg_1$. Varying concentrations of ginsenoside-$Rg_1$ (0, 25, 50 and $100{\mu}M/ml$) were used in the extender during cryopreservation to protect the DNA of thawed sperm, thereby increasing the viability and motility rate as evaluated using a computer-assisted sperm analysis (CASA) method. The results derived from CASA were used to compare the fresh, control, and ginsenoside-$Rg_1$ groups. Sperm motility and the number of progressively motile sperm were significantly (p<0.05) higher in the $50{\mu}M/ml$ ginsenoside-Rg1 group ($61.0{\pm}4.65%$) than in the control ($46.6{\pm}7.02%$), $25{\mu}M/ml$ ($46.2{\pm}4.76%$), and $100{\mu}M/ml$ ginsenoside-$Rg_1$ ($52.0{\pm}1.90%$) groups. However, the velocity distribution of post-thawed sperm did not differ significantly. Membrane integrity and MMP staining as revealed using flow cytometry were significantly (p<0.05) higher ($91.6{\pm}0.82%$) in the $50{\mu}M/ml$ ginsenoside-$Rg_1$ group than in the other groups. Here, we report that ginsenoside-$Rg_1$ affects the motility and viability of boar spermatozoa. Moreover, ginsenoside-$Rg_1$ can be used as a protective additive for the suppression of intracellular mitochondrial oxidative stress caused by cryopreservation.
