Association of Oxidative Stress Biomarkers and Antioxidant Enzymatic Activity in Male Infertility of North-East India

摘要

Introduction Oxidative stress is a common pathology seen in approximately half of all infertile men. In a normal situation, the seminal plasma contains antioxidant mechanisms which are likely to quench these reactive oxygen species. However, during infertility complications these antioxidant mechanisms may downplay and create a situation which is called oxidative stress. Objective The aim of the present study was to assess the levels of lipid peroxide (LPO), protein peroxide (PPO) and activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPX) in blood and semen samples of an infertile male population from North-East India. Method We measured LPO, PPO, SOD and GPX in a total of 50 infertile individuals. For the study 20 fertile donors served as the control group. Result Patients with male factor infertility had significantly higher LPO and PPO levels (60.84?±?3.55 and 72.84?±?3.66; P
