Study claims Covid-19 can negatively impact a man’s sperm, experts are skeptical

A Covid-19 infection could negatively impact the quality of a man’s sperm, potentially affecting fertility, according to a study published in the journal Reproduction. But some experts are skeptical and have criticised the study, one saying any virus can temporarily cause a drop in sperm count.

The study claims a coronavirus infection can cause impairments to a man’s semen. German researchers say those with Covid-19 had a change in sperm concentration, shape and mobility as well as inflammation and oxidative stress in the sperm cells. Those with more severe Covid-19 infections had the most changes to their sperm, according to the study.

“This report provides the first direct evidence to date that COVID-19 infection impairs semen quality and male reproductive potential.”

The study by Justus Liebig University Giessen in Germany examined the sperm of 84 fertile men with Covid-19 and 105 fertile men without the virus. Their semen was analysed every 10 days over the course of a 60 day trial. Lead researcher and doctoral student Behzad Hajizadeh Maleki says the more severe the Covid-19 infection, the more changes there were to the sperm.

“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-19 patients, and the magnitude of these changes were also related to disease severity.”

But catching other viruses, like the flu, can also cause a temporary drop in sperm, sometimes for a few months, according to consultant in reproductive endocrinology and andrology at Imperial College London, Channa Jayasena.

“This makes it difficult to work out how much of the reductions observed in this study were specific to Covid-19 rather than just from being ill.”

A professor of andrology at the UK’s University of Sheffield in South Yorkshire, Allan Pacey, told CNN that he has reviewed numerous studies on the subject and says “any measurable effect of coronavirus on male fertility was probably only slight and temporary.”

    First of all….there is NO “Covid-19″…There has NEVER been any proof/isolation of this “virus”….NEVER….secondly, the so called “Vaccine” DOES HAS the risk of causing fertility issues among both women and men plus many many other health risks including death…..but thirdly, there is NO vaccine at all, only genetic theraphy…..transhumanism….very risky stuff….but who is so stupid that wants to be lab rat for the billion dollar drug companies taking a fake vaccine for a “virus” with less death rate than an ordinary season flu?? I guess all the Zombies……

      But Rob, if “there is NO “Covid-19” then how can it have “less death rate than an ordinary season flu??”

      Bit of a tricky one, that 🙂

    But Rob, ignoring whether there is a virus or not, Covid-19 is real and in our lives now. It may be that in the near future one has to have proof of vaccination in order to enter certain buildings, shops, to travel abroad, even to enter your work office or as a condition of your job. What would you do then? Whilst the government may not make it mandatory to be vaccinated, it is effectively just that in order to live any semblance of a life. You could still choose to isolate yourself and not take it but what if a year or two later you got cancer and died or hit by a car and died or dies by a thousand other possibilities? Wouldnt you rather take the risk of being vaccinated and live some form of a normal life until your demise? I mean, we all have to go one way or another right. I would much prefer to be vaccinated and travel again for even just one year and then die from a side effect than not be vaccinated, have a miserable life for 20 more years and then die from cancer. Theres no enjoyment in just surviving, but there is in living.

    Unfortunately this zombie will lose his job if he refuses to take the jab. I’m not alone. Is it possible loads of places will refuse entry until proof of vaccination. IS THIS POSSIBLY THE NEW WORLD’S I.D CARD?……LOVE TO HEAR ANYONE’S OPINION ON THIS?…….
