Effect of polyunsaturated fatty acids of the alpha-linolenic series in the lipid composition of rat testicles during development.
The effect of 22:6 omega 3 acid provided by dietary fish oil on the lipids composition of rat testes and liver during the development of the germinal tissue, was investigated. Results were compared to those obtained in animals fed on sunflower seed oil (linoleate) and methyl palmitate. At 7 and 9 weeks of age, both fish oil and methyl palmitate evoked a decrease of phosphatidyl-choline and ethanolamine and an increase of triacylglycerols. However, only in the group of rats administered with omega 6 or omega 3 acids and not in the palmitate group, the maturation of germinal epithelium was normal. It is suggested, as in a previous work, that 22:6 omega 3 may functionally replace 22:5 omega 6 in rat germinal tissue.
