Quercetin is a flavonoid with antioxidant, anti\u2010inflammatory, and lipolytic actions and is a potential supplement to combat the oxidative stress caused by HFD and its harmful effects on reproduction. This study evaluated the effects of quercetin supplementation at doses of 10 and 20\u00a0mg\/day on reproductive parameters and testicular oxidative stress in Wistar rats fed a diet rich in pork fat and fructose.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method of study<\/jats:title><jats:p>The rats received a basal diet or HFD for 2\u00a0months, after which the animals fed the HFD received daily supplementation of 0, 10, or 20\u00a0mg of quercetin for another 2\u00a0months.
