Male infertility estimated about 20-70% of couples or >30 million men worldwide. The goal of this study was to elucidate the interrelations between oxidative stress (O.S) in seminal fluid and antioxidant inducing disruption of spermatogenesis. Twenty four infertile patients aged (23-41) years were involved in this study. Which were received α- tocopherol (vitamin E). This group (vit E group) was sub classified according to the WHO criteria (2010) into three different subgroups: oligoasthenoteratozoospermia (OAT) Asthenoteratozoo- spermia (A.T), and Asthenozoospermia (Astheno.). The control group consist of samples obtained from healthy donors of proven fertility (n=23). The main parameters were determined in seminal fluid of infertile patients and healthy men are the sperm and seminal plasma Malondialdehyde (MDA) concentration, and vitamin E concentration in seminal plasma. The results showed that, there was a high significant decrease (p≤0.001) in sperm parameters (concentration, progressive motility and normal morphology), and vitamin E concentration in infertile group compared with that fertile group.After analyzing the statistically difference in the different measured parameters between the vit E group after treatment, in comparison with that of before treatment; the following was observed A high significant increase (p≤0.001) were found in progressive motility, sperm [MDA] (MDAp), vitamin E concentration, and significant increase (P ≤0.05) in the sperm concentration. From all of these observations, it can be concluded that O.S contributes most likely to sperm damage and may be responsible for poor seminal fluid characteristic of the infertile patients involved in the present study. Antioxidants α-tocopherol (vitamin E) plays an important role in the improvement of seminal fluid parameters.
