A new study seeks to explain why men infected by coronavirus generally show more severe symptoms and have an increased risk of death over women. Focusing on ACE2 receptors, researchers found the testes, along with the lungs and kidneys, were among areas of the body with the highest ACE2 expression. ACE2 could not be detected in ovarian tissue. The findings back up a previous study that reported male COVID-19 patients experienced impaired testicular function. This suggests the testes may be significantly affected when men develop coronavirus.
