TL;DR: Oxidation-reduction potential (ORP) can be a useful clinical biomarker for the classification of MOSI, as it takes into account the levels of both oxidants and reductants (antioxidants) and may provide a more targeted, reliable approach for administering antioxidant therapy while minimizing the risk of antioxidant overdose.
Journal ArticleDOI
Sex-Specific SARS-CoV-2 Mortality: Among Hormone-Modulated ACE2 Expression, Risk of Venous Thromboembolism and Hypovitaminosis D.
Sandro La Vignera,Rossella Cannarella,Rosita A. Condorelli,Francesco Torre,Antonio Aversa,Aldo E. Calogero +5 more
TL;DR: Evidence that sex hormones are able to modulate the expression of ACE2 could help in interpreting epidemiological results and in designing more appropriate intervention strategies, according to the recent evidence of an increased frequency of venous thromboembolism in patients with COVID-19.
Journal ArticleDOI
Oxidative stress and medical antioxidant treatment in male infertility
TL;DR: Overall, the data published suggest that no single antioxidant is able to enhance fertilizing capability in infertile men, whereas a combination of them seems to provide a better approach.
Journal ArticleDOI
Cigarette smoke extract immobilizes human spermatozoa and induces sperm apoptosis.

TL;DR: Since transmission of smoking-induced sperm DNA alterations has been found in pre-implantation embryos, and this may predispose offspring to a greater risk of malformations, cancer and genetic diseases, men seeking to father a child are recommended to give up smoking.
