Exploring the link between testosterone levels and COVID-19 in men

SARS-CoV-2, TESTOSTERONE AND MALE FRAGILITY (PROTEGGIMI): A MULTIDIMENSIONAL RESEARCH PROJECT

IRCCS San Raffaele · NCT06177002

This study is trying to see if low testosterone levels make men more likely to get seriously ill from COVID-19.

What this trial studies

This observational study investigates the relationship between testosterone levels and susceptibility to COVID-19 in male patients. It aims to collect biological data from hospitalized male patients who have tested positive for SARS-CoV-2, as well as from healthy male donors. The study seeks to understand whether testosterone deficiency may contribute to increased vulnerability and severe outcomes in men infected with the virus. By analyzing these hormonal factors, the research hopes to shed light on potential pathophysiological mechanisms involved in COVID-19 severity among males.

Who should consider this trial

Good fit: Ideal candidates include male patients over 18 years old who are hospitalized with COVID-19 or healthy male donors over 18 years old.

Not a fit: Patients under 18 years old or those unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how testosterone levels affect COVID-19 outcomes in men, potentially guiding treatment strategies.

How similar studies have performed: While the specific relationship between testosterone and COVID-19 is still being explored, preliminary data suggests that hormonal factors may influence disease severity, indicating a novel area of investigation.
