The effect of 22∶6ω3 acid provided by dietary fish oil on the development of germinal tissue of rat testes, fatty acid composition of lipids, and linoleic or α‐linolenic acid Δ6 desaturation capacity was investigated. Results were compared to those obtained in animals fed methyl palmitate and sunflower seed oil (linoleate). At 7 and 9 weeks of age, development of germinal tissue of animals fed fish oil was normal. The fatty acid composition showed a decrease in 22∶5ω6 acid content and an increase in 22∶6ω3 acid in triacylglycerol, phosphatidylcholine, and phosphatidylethanolamine. The fatty acid Δ6 desaturation capacity of testicules microsomes was increased. It is suggested that 22∶6ω3 acid may functionally replace 22∶5ω6 acid in germinal tissue.
