【 摘 要 】

Oxidative stress is one of the leading causes of sperm dysfunction. Excessive amounts of reactive oxygen species can damage sperm membranes and disrupt their DNA integrity, which affects not only the likelihood of getting pregnant naturally, but also the clinical outcomes of assisted reproductive technologies and the risk of miscarriage. Sperm cells are extremely vulnerable to oxidative stress, given the limited functional reserve of their antioxidant systems and the DNA repair apparatus. Lifestyle factors, most of which are modifiable, often trigger generation of reactive oxygen species.  Both the lifestyle modification and use of antioxidant dietary supplements are adequate and compatible ways to combat male oxidative stress-associated infertility. The search for other internal and external sources of reactive oxygen species, the identification of the etiology of oxidative stress and treatment of respective diseases are necessary for the successful regulation of redox processes in the male reproductive system in clinical practice, which is required not only to overcome infertility, but also to prevent induced epigenetic disorders in subsequent generations. The article presents the analysis of the molecular mechanisms of male idiopathic infertility. The authors provide an overview of how to prevent oxidative stress as one of the causes of subfebrile fever. The article provides an overview of modern therapeutics, as well as the options for eliminating the consequences of the effect of reactive oxygen species on spermatogenesis and male reproductive system in general.
