Androgen deprivation strategies could help mitigate SARS-CoV-2 infection

Since the beginning of the COVID-19 pandemic, researchers have noted that women are generally less severely affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This has led to the exploration into estrogen and androgens' role in the hyperinflammatory clinical phenotypes of COVID-19. A recent study published on the preprint server bioRxiv shows that drugs targeting androgens and TMPRSS2 inhibitors may potentially combat the pandemic.

Estradiol appears to help in female SARS-CoV-2 infection

A new study published on the preprint server medRxiv in August 2020 shows that the risk of infection is high for pre-menopausal women but the risk of death is much higher for men in the same age group and throws light on the protective nature of estradiol therapy in post-menopausal women.

Estrogen modestly protective against COVID-19?

Almost from the beginning, scientists have been struck by the disproportionately higher numbers of men and older adults who have developed severe COVID-19 disease compared to younger individuals and women. Prior research has shown that in 37 of the 38 countries from which sex-stratified data was available, males were at a higher risk of death. Also, post-menopausal women are at increased risk of severe COVID-19. However, the biological underpinnings of this have been less visible.
