Role of antioxidants in treatment of male infertility: an overview of the literature
Key Points Male infertility is a complex lifestyle-related disorder Oxidative stress has adverse effects on the structural and functional integrity of sperm and is a major cause of defective sperm function and male infertility Oxidative stress causes damage to both mitochondrial and nuclear DNA and also affects the sperm epigenome, resulting in infertility, recurrent pregnancy loss, poor pregnancy outcomes and an increased disease burden in the offspring Spermatozoa are most vulnerable to oxidative stress and oxidative DNA damage (ODD) as these cells have limited antioxidant defence mechanisms and a limited capacity for detection and repair of DNA damage A number of intrinsic and extrinsic factors can regulate oxidative stress, and these must be maintained at moderate levels for optimal sperm function and the maintenance of cellular homeostasis and redox-sensitive signal-transduction pathways Simple lifestyle modifications and interventions can substantially reduce levels of testicular inflammation, oxidative stress and ODD and improve the quality of life of infertile couples Abstract DNA damage, largely owing to oxidative stress, is a leading cause of defective sperm function
In line with the research that showed increase in the abundance of Akkermansia species, it has been demonstrated that use of metformin was essentially associated with an increased production of SCFAs (Wu H
A flat payment rate also reduces the incentive to innovate, perform relevant studies, and seek an FDA approval requiring proof of wound treatment or healing
Moreover, maternal stress during pregnancy and premature birth are environmental factors associated with ADHD [3]
