It is very important to identify the factors which affect normal sperm functions. New Bio-chemical parameters in seminal plasma were analyzed to determine the biochemical factors that affect normal sperm function. The research groups consists of infertile groups Asthenozoospermia (n=31) and Normozoospermia (n=27) with a healthy men as a control (n=24). The patients have been selected and examined according to the World Health Organization (2010). In addition the seminal fluid analysis the biochemical parameters were analyzed in the seminal plasma of each sample including; Total antioxidant capacity, Catalase, Glutathione Reductase , glutathione and Malondialdehyde.Results showed a decrease in seminal plasma total antioxidant capacity of Astheno-zoospermia and Normozoospermia , and a significance decrease in catalase level for both infertile groups, Malondialdehyde level significantly increased in both infertile groups and Glutathione level significantly decreased in Asthenozoospermia group as compared to control group. Antioxidants have an important role in sperm protection via disturbing the balance in ROS production which destroys sperm plasma membrane causing loss sperm activity and it's ability to fertilize the egg.
