Abstract

Background: The aim of this study was to investigate the effect of fed fish oil (FO) with or without vitamin E for mothers on the testis cells of male offsprings.

Materials and Methods: Sixty mature female NMRI mice were divided into different groups: control (CTR; Standard diet(vitamin E 50 mg IU/kg) pre and postnatal period); I) Gavages 0.01 ml/day/mother fish oil (FO)+CTR diet during prenatal period; II) Gavages FO+CTR diet during postnatal period; III) consumed VITE(125 mg IU/kg) 2.5 folded greater than standard recommendations(2×)during prenatal period; IV)consumed VITE(2×)diet during pre and postnatal period; V)consumed VITE(2×)diet during postnatal period; VI) Gavages FO+VITE(2×) diet during prenatal period; VII) Gavage FO+VITE(2×)diet during postnatal period ;VIII) Gavages FO+VITE (2×)diet during pre and postnatal period. After weaning, the testes were collected and histological data were analyzed using SAS software by Duncan test.

Results: testes cells length, width and weight was lower in offspring which their mothers fed FO+CTR diet during prenatal, (p<0.05).Vitamin E consumption during postnatal period improved these parameters (p<0.05). Spermatogoni (47 vs. 43), spermatocyte (43 vs. 34), Spermatid (63 vs. 44), Sertoli (0.9 vs. 2), and Leydig (3 vs. 1.7) were increased as FO+VITE was used than CTR (p<0.05).

Conclusion: The positive effects of supplementation maternal diet by FO with VITE or sole VITE was observed. Thus, antioxidants should be consumed along with omega-3 fatty acids in maternal diet.
