Testosterone and Covid‐19: An update

There is overwhelming evidence to suggest that male gender is at a higher risk of developing more severe Covid‐19 disease and thus having poorer clinical outcomes. However, the relationship between testosterone (T) and Covid‐19 remains unclear with both protective and deleterious effects on different aspects of the disease suggested. Here, we review the current epidemiological and biological evidence on the role of testosterone in the process of SARS‐CoV‐2 infection and in mediating Covid‐19 severity, its potential to serve as a biomarker for risk stratification and discuss the possibility of T supplementation as a treatment or preventative therapy for Covid‐19.
