Lard and/or canola oil-rich diets induce penile morphological alterations in a rat model

PURPOSE: To investigate the effect of dietary lipid quantity and/or quality on penis morphology in adult rats. METHODS: Thirty-eight male Wistar rats were divided into 4 groups: normal lipid diet (NL), high-fat diet rich in saturated fatty acids (HF-S), high-fat diet rich in polyunsaturated fatty acids (HF-P), and high-fat diet rich in saturated and polyunsaturated fatty acids (HF-SP).

The HF-S and HF-...
