چکیده
This study was aimed to investigate the effects of ۱۷ 𝛽-estradiol (E۲) and 𝛼-zearalenol (α-ZOL) on motility parameters, plasma membrane integrity, levels of produced nitric oxide (NO) and total antioxidant capacity of Ghezel ram sperm during the liquid storage at ۴ ˚C, for various periods of time. Semen samples were collected from four rams and diluted with Tris–egg yolk extender and supplemented with E۲ (۱۰۰ µmol) or different concentrations of α-ZOL (۱۰۰ pmol, ۱۰۰ nmol and ۱۰۰ µmol) at a final concentration of ۲۰۰ × ۱۰۶ sperm per mL. We failed to show any significant effect of E۲ at ۱۰۰ µmol concentration on ram’s sperm parameters while α-ZOL resulted in a significant decrease of plasma membrane integrity at ۱۰۰ µmol concentration (۵۵.۴۰% for α-ZOL vs ۶۲.۲۰% for control) after ۹۶ hr incubation. Alpha-ZOL had decreasing effect on sperm motility parameters including curvilinear velocity and average path velocity at ۱۰۰ µmol concentration after ۹۶ hr storage. Although remarkable reduction of total antioxidant capacity at high concentration of α-ZOL and long incubation time was found, however no significant changes were recorded in NO level during storage time. It was concluded that the detrimental effect of α-ZOL on ram sperm might be attributed to its induced oxidative stress and damage to the plasma membrane.کلیدواژه ها
