In the face of SARS-CoV-2 infection, an uncontrolled and unregulated response of the innate immune system can cause local and multisystem organ damage, which is characteristic of patients admitted to hospitals and who die from this virus. See some of the factors involved in the severe pathological pictures of this infection, mainly in men, in articles published between 2010 and 2021 and specialized books. Research shows that age, gender, race, and blood group (specifically A), coupled with factors such as immunosenescence and comorbidities, are crucial in the severity of the disease. Finally, it is suggested that, although men and women have the same probability of becoming ill with COVID-19, men are more likely to die because they have more ACE2 receptors in plasma, greater esterase activity, produce more proinflammatory cytokines, and respond differently to hormones (testosterone favors the innate immune response more while estrogens favor the adaptive one) and to the effects of dopamine inhibitors, involved in the inflammatory response. In addition, androgen hormones regulate the TMPRSS receptor and induce metalloproteases involved in adhesion and fibrotic processes.
