Antioxidants are natural or synthetic substances that delay oxidation through one or more mechanisms, such as scavenging free radicals, inhibiting lipid peroxidation, and complexing with metals, inhibiting tissue destruction via oxidation. Antioxidants are commonly used in animal feed and the food industry to prevent the oxidation of animal-origin products. Moreover, natural oxidants are used increasingly in animal reproduction, especially for semen preservation. In this context, this study aimed to review the applications of natural antioxidants in animal reproduction. We observed that the bulk of the natural antioxidants, approximately 80.4%, were commercially acquired and used mainly for semen cooling/freezing (72%) with promising results (90%) in Sus scrofa (boar), Capra aegagrus hircus (goat), Gallus gallus domesticus (rooster), and Ovis aries (ram). However, further studies are needed to help determine the appropriate dosage of natural antioxidants for applications.Keywords: cryopreservation; free radicals; lipid peroxidation; oxidative stress; vitamin E.
