In order to assess the effect of Omega-3 PUNFs on the quality of semen in albino rats in order to get benefit from its use. Fifty mature male albino rats weighing 250-300g and 4-6 months of age were allocated randomly into 2 equal groups; group A that kept as control (n=25) and group B (n=25) where, rats subjected to oral administration of omega-3 for 2 months at 375mg/kg body weight daily. Semen was collected from both groups after 8 weeks for detecting the sperm motility, count and abnormalities. Sera were used for determination of testosterone level. In addition, testis homogenate was used for measuring catalase and malondialdehyde activity. The body weight and sex organs (testis, prostate gland and seminal vesicles) weights were recorded in both groups. Histological examination of testis was performed. We found a significant increase in sperm motility, count, testosterone and catalase concentrations with a decrease in sperm abnormalities percentage and malondialdehyde concentration in omega-3treated group as compared with control. No change in both body and sex organs weights was observed in treated group. In addition, numerous sperms in the lumen of the seminiferous tubules with numerous active spermatocytes were observed in the testis of omega-3treated group. It was concluded that Omega-3PUNFs had a positive and useful effects on the male fertility and could improve semen quality.
