Dietary Supplementation with Omega-3 Poly Unsaturated Fatty Acids Improves the Fertility in Adult Male Rats

: This study aimed to assess the role of omega-3 PUNFs on male fertility using albino rats in order to get benefit from its use. For this study, fiftsy mature male albino rats weighing 250-300 g and aged 4-6 months 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 in a dose of 375 mg kg G 1 body weight daily. The 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. The obtained results revealed that group B; omega-3 treated group showed a significant increase in sperm motility, count, testosterone and catalase concentrations with a significant decrease in the percentage of abnormal spermatozoa and malondialdehyde concentration as compared with group A; control. Nochange in both body and sex organs weights was observed in treated group. In addition, numerous sperms in the lumen of the seminiferous tubules
