Men have higher levels of angiotensin-converting enzyme 2 than women, show the results of a European study that may help explain why they are more vulnerable to COVID-19 which uses ACE2 to enter cells.

The study also found that ACE inhibitors or angiotensin receptor blockers (ARBs) did not lead to higher ACE2 concentrations and should therefore not increase the COVID-19 risk for people taking them.
