Severe acute respiratory syndrome coronavirus (SARS-CoV-2) disease (COVID-19) appears to have a higher mortality rate in presence of comorbidities and men. The latter suggests the possible sex-dependent susceptibility. An enzymatic system involved this different predisposition could be represented by angiotensin converting enzyme 2 (ACE2). ACE2 is activated down-regulated spike protein virus allows penetration SARS-CoV-2 into epithelial cells myocardium. Data on experimental animal shown...

Although the prevalence of sub-infertility in diabetic patients childbearing age is known, mechanisms by which diabetes mellitus (DM) causes male infertility are not completely explained. This detrimental effect achieved with a variety that include pre-testicular, testicular, and post-testicular pathogenetic moments can be different type 1 (DM1) 2 (DM2) because diabetes, duration disease, glycemic metabolic compensation. Aim this study was to evaluate whether disease considered risk factor...

Background. Reduced testicular volume (TV) (<12 cm(3)) is associated with lower function. Several studies explored the conventional sperm parameters (concentration, motility, and morphology) endocrine function (gonadotropins testosterone serum concentrations) in patients reduction of TV. No other have been examined. Aim. This study aims at evaluating some biofunctional by flow cytometry semen men reduced TV compared that subjects normal Methods. 78 without primary scrotal disease were...
