Comparison of anti-oxidant enzymes activity and levels of zinc and selenium in sperm and seminal plasma between fertile and idiopathic infertile men

Abstract

Background: Reactive oxygen species (ROS)-induced lipidperoxidation can lead to dysfunction of sperm and thereby, infertility may be occurred. So, always there is a balance between amount of ROS and anti-oxidant molecules in semen. Anti-oxidant enzymes of sperm; superoxide dismutase (SOD), glutathione peroxidase (GPX), catalse and zinc and selenium can protect it from destructive effects of ROS. Hence, the present study was designed to compare the activities of these enzymes and trace elements between fertile and idiopathic infertile men.
