P-46: The Effect of Oral Antioxidants on Male Infertility
Background: The use of antioxidants in treatment of infertile men has been suggested, although the evidence base for this practice is unclear. A systematic review of randomized studies was conducted to evaluate the effects of oral antioxidants (vitamins C and E, zinc, selenium, folate, carnitine and carotenoids) on sperm quality and pregnancy rate in infertile men. Materials and Methods: MEDLIN...
متن کاملMechanisms of male infertility: role of antioxidants.
Defective sperm function is the most common cause of infertility, and until recently, was difficult to evaluate and treat. Mammalian spermatozoa membranes are rich in poly unsaturated fatty acids and are sensitive to oxygen induced damage mediated by lipid peroxidation. Hence, free radicals and reactive oxygen species [ROS] are associated with oxidative stress and are likely to play a number of...
متن کاملOxidative stress and antioxidants in male infertility: a difficult balance
Infertility is one of the most stressful conditions amongst married couples. Male factor infertility is implicated in almost half of these cases. Recent advances in the field of reproductive medicine have focused the attention of many researchers to consider reactive oxygen species (ROS) as one of the mediators of infertility causing sperm dysfunction. Although, ROS is involved in many physiolo...
متن کاملRole of oxidative stress and antioxidants in male infertility.
Oxygen toxicity is an inherent challenge to aerobic life, including spermatozoa, the cells responsible for propagation of the species. How this toxicity affects the spermatozoan in its interactions with the ovum is still unknown. An increase in oxidative damage to sperm membranes, proteins, and DNA is associated with alterations in signal transduction mechanisms that affect fertility. Recent ev...
متن کاملFemale Infertility and Antioxidants
Aim: Many studies have implicated oxidative stress in the pathogenesis of infertility causing diseases of the female reproductive tract. The aim of this study was to review the current literature on the effects of antioxidant therapy and to elucidate whether antioxidant supplementation is useful to prevent and/or treat infertility and poor pregnancy outcomes related to various obstetric and gyn...
