Could Covid cause erectile dysfunction? Doctors say blood vessels damaged by ...

Some doctors suspect that the coronavirus could lead to higher risk of men developing erectile dysfunction.

So far, their fears are based on anecdotal evidence from patients reporting erection problems after having the virus.

A few small-scale studies have also linked the condition, but doctors say more are needed. 

One way Covid could lead to erectile dysfunction is through pneumonia.

Pneumonia can inflame the blood vessels, which can restrict blood flow.

Erections are purely caused by blood flow, so anything that harms this could have a knock-on effect.

Pneumonia can also damage people's lungs, which can affect blood oxygen levels.

This can make it difficult for men to maintain an erection.

Covid could also infect testosterone-producing cells in the testicles called Leydig cells.

A drop in these cells can affect libido and desire.

Dr Emmanuele Jannini, professor of endocrinology and medical sexology at the University of Rome Tor Vergata, said reduced sense of smell could also be linked with erectile dysfunction.

Not being able to smell could prevent arousal, he said.

Dr Jannini said the link could even be linked to poor mental health, with the pandemic leading to higher stress levels.

This could stop men from getting aroused, he said.
