Considering the compelling amount of studies focused on patients in the active phase of COVID-19 disease and the scarcity of studies focused on patient cured from disease aimed at evaluating the sequelae of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, the purpose of the study is to investigate, in patients recovered from COVID-19 disease: 1) whether SARS-CoV-2 infection has induced in male patients, a primary (testicular) and / or secondary (pituitary) damage to the hypothalamic-pituitary-testicular hormonal axis, structural and / or functional damage to the testis and penis, sexual dysfunction or fertility disorders; 2) the prevalence in male and female patients of chemosensory symptoms (olfactory dysfunction) and assess whether there is a correlation between the prevalence, severity, duration and eventual persistence of olfactory dysfunction and the severity of COVID-19 disease. Patients will be evaluated at baseline (at discharge from infectious and/or pneumology unit) and after 3- 12 months. A better definition of the prevalence and type of sequelae after recovery from COVID-19 disease could significantly improve the therapeutic management and long-term follow-up of these patients, with a relevant impact in terms of health resources and public health.
