Effect of exposure to CeO2 nanoparticles on ram spermatozoa during storage at 4 °C for 96 hours

Abstract

We reported beneficial effects of CeO₂ NPs on kinematic and morphologic parameters of ram semen, such as motility and membrane integrity following 96 h of exposure. Furthermore, we also proved no genotoxic effects of CeO₂ NPs. These effects could not be related to an antioxidant activity of CeO₂ NPs, since ROS levels in exposed cells were similar to those of unexposed ones.
