Abstract
The main sources of ROS during cryopreservationCellular ROS during cryopreservation is genereated from two main sources, endogenous or exogenous, and is present as either the superoxide radical (O - 2 ), hydrogen peroxide (H 2 O 2 ), or hydroxyl radical (OH).O - 2 is generally unreactive and has a short half-life (5).Gametes can remove it through the endogenous antioxidant system (3).Antioxidants
