description: The present study explored the effect of dietary oils on lipid composition, antioxidant status, and the activity of the main steroidogenic enzymes in the testis. Forty Wistar rats were randomly assigned to one of four groups ( n = 10) fed for 60 d on the same basal diet plus different lipid sources as commercial oils: soybean, olive, coconut, or grapeseed. After sacrifice, testicular lipids and fatty acid composition, free radical biomarkers, antioxidant levels, hormones, and steroidogenic enzymes were determined. The lipid composition of diets produced significant changes in neutral/phospholipids, free/esterified cholesterol, and plasmalogen proportion. Fatty acid patterns of these lipids were also strongly modified, influencing the double bond index. We also found a close correlation between the type of diet and the generation of free radicals. The oxidative stress in testes was higher with the grapeseed oil–supplemented diet and...
