Abstract

The aim of the present study was to evaluate the antioxidant properties of oleuropein on ethanol-induced oxidative stress in the rat testis. 32 adult male Sprague–Dawley rats were divided into four equal groups: the first group as a control, the second group of rats were given ethanol (4 g/kg), the third group received oleuropein (15 mg/kg), and the fourth group of rats were supplemented of oleuropein (15 mg/kg) and after 120 min were ingested via ethanol (4 g/kg) orally. Oleuropein could prevent the reduction of motility and plasma membrane integrity of the spermatozoa against ethanol-induced oxidative stress in treated rats (P < 0.05). While, thiobarbituric acid reactive substances (as a lipid peroxidation marker) concentration was decreased significantly in the oleuropein plus ethanol group compared to the ethanol group (P < 0.05). Notably, glutathione peroxidase and superoxide dismutase activity increased significantly in the ethanol-treated animals compared to controls and total glutathione (GSH-content) increased significantly in ethanol-treated rats compared to the oleuropein group. Our findings suggest that oleuropein possesses beneficial antioxidant effects on ethanol-induced sperm toxicity, subsequently enhancing sperm motility and plasma membrane integrity.

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
