Effect of pollack liver oil on lipid metabolism in rat testes

Rat testes were examined by biochemical and histochemical methods after 1, 3, 6, and 12-month pollack liver fat-supplemented diet (0.1 g/kg). Phospholipid concentration in the testicular tissue increased by 16% and cholesterol concentrations decreased by almost 20% after feeding fish oil for 1-3 months, while after 6-12-month diet further increase in cholesterol level in the testes and degeneration of some gonadal cells were noted. The most pronounced changes were seen in more differentiated elements of the spermatogenic epithelium in convoluted tubules.
