Superoxide dismutase (SOD), glutathione (GSH), and catalase(CAT) are well-known enzymatic antioxidants in the seminal plasma and sperm,encoded by NRF2 (4), SOD, CAT,glutathione S-transferase (GST), and glutathione peroxidase (GPX) genes.Alteration in these genes may lead tomale infertility, and it seems that the improved activity ofthese genes may improve male fertility (5). Here, CAT is linked to Infertility.
