COVID could affect sperm quality and reduce fertility in infected men, new research has found.
A study at a German University claims the virus can cause increased sperm cell death and inflammation.
Published in Reproduction, the research found 84 fertile men with coronavirus saw stress in sperm cells rise by more than 100 per cent.
It also discovered sperm cell shape was altered by 400 per cent which, according to the study, can lead to trouble conceiving.
But Prof Allan Pacey, Professor of Andrology, University of Sheffield, said: “That the study was able to repeat these measurements every ten days over a 60 day period is no mean feat and this is a nice part of the study.
“However, since sperm production takes just under three months (roughly) to be completed from start to finish, in my opinion they ended the study 30 days too soon.”
“It would have been more useful to see whether there was a difference at 90 days between the two groups. A paper published last year suggested only a small difference in sperm concentration existed by that time.”
Multiple studies have looked at the effect of the bug on men’s reproductive organs – with some finding there could be knock-on issues for fertility, at least temporarily.
Lead Researcher Behzad Hajizadeh Maleki added: “These effects on sperm cells are associated with lower sperm quality and reduced fertility potential.
“Although these effects tended to improve over time, they remained significantly and abnormally higher in the Covid-patients, and the magnitude of these changes were also related to disease severity.”
Scientists at Assam University warned in their latest research a high temperature has been known to cause damaging swelling in men’s testicles.
However the new Kent strain can include main symptoms of muscle aches and a sore throat, with less reports of a loss of taste or smell and a fever.
