**5. Conclusion**

As research studies show, it is evident that supplementing semen extenders, with some anti‐ oxidants, such as vitamin E and its synthetic analogue, BHT, and fatty acids such as alpha linoleic acid, is beneficial to the sperm to endure the physical and biochemical changes and challenges faced during cryopreservation and results in a superior postthaw quality available for AI. However, it is worth noting that supplements work best at a particular optimum con‐ centration that varies with the type of extender used, as well as the species of the animal from which the sperm has come from. Hence, prior use of a particular antioxidant or fatty acid as a supplement, proper investigation needs to be conducted to determine their optimum concen‐ tration to be added into a specific semen extender type.
