Antioxidants and semen quality

Avian spermatozoa are characterised by high proportions of polyunsaturated fatty acids (PUFA) which is associated with increased susceptibility to reactive oxygen species (ROS) and lipid peroxidation.   Recent advances in avian reproduction have focused on the potential of ROS as one of the prime mediators of infertility. Although ROS are involved in many physiological functions of spermatozoa, their excessive production may result in oxidative stress. The production of ROS is enhanced during u
