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.

Methods: Semen specimens were collected from 30 infertile men with proven infertility by an urologist, and 30 fertile men as control donors, with age range between 20-40 years old. Semen analysis was conducted by CASA method. Atomic absorption method was used for measuring of zinc and selenium concentration. Activity assays of SOD and GPX were performed by Randox Kits. Aebi method also was applied for evaluation of catalase activity.

Results: There was no difference between the activities of enzymes in fertile men and infertile ones. Also, it wasn't seen any difference in the selenium and zinc levels of seminal plasma. There was no relationship between evaluated items with sperm parameters. Only, in asthenoteratospermic individuals negative correlations were found between GPX and sperm motility, selenium and sperm morphology. Also, in these individuals ,there was a positive correlation between SOD and catalse activity.

Conclusion: Measuring activities of SOD, GPx, and catalase and the contents of zinc and selenium of seminal plasma do not appear to be suitable tools for determining the fertility potential of sperm.
