متن کاملP-67: Reactive Oxygen Species, MDA and NO Concentration of Testicular Extract and Their Effect on Sperm Parameters and IVF Outcome in Hyperprolactinemic Adult Male Mice
Background: ROS are free radicals that have a significant role in many of the sperm physiological processes. In the presence of polyunsaturated fatty acids such as sperm plasma membrane,ROS triggers a chain of chemical reactions called lipid peroxidation.The aim of this study was to determine and compare the concentration of MDA and NO in testicular extract of hyperprolactinemic adult male mice...
