Men with more CAG repeats in the androgen receptor gene and lower testosterone levels may experience more severe COVID-19.
research Sex differences in COVID-19: the role of androgens in disease severity and progression
Male hormones like testosterone may make COVID-19 worse, and testing for sensitivity to these hormones could help predict how severe a patient's symptoms might be. Treatments that reduce these hormones are being explored.
