Evaluation of Current Antioxidant Profile in Semen

The freezing and storage of the sperm are used cryopreservation germplasm in livestock breeding, genetic improvement indigenous species, preservation rare races, successful tolerance to environmental changes international exchanges. Both thawing process causes large volume cell fluid. Spermatozoon removes most its cytoplasm at differentiation stages lacks cytoplasmic component that contains antioxidants counteract harmful effect reactive oxygen species lipid peroxidation. Therefore, sensitivity spermatozoa peroxidation increases during sperm, which creates a significant mechanical stress on membrane. Oxidative is caused by oxygen-derived oxidants, commonly known as ROS, an imbalance between ability biological systems easily detoxify or repair damaged reagents. Uncontrolled ROS production, exceeds antioxidant capacity seminal plasma, oxidative spermatozoa. All cellular components, including lipids, proteins, nucleic acids, sugars, potential targets stress. Antioxidants control chemical degradation substrate oxidation, neutralizing free radicals, thereby it minimize risk damage cryopreservation.
