Men suffer a long-term drop in semen quality after Covid - even if the infection was mild, reveals new research. Scientists found that more than three months after suffering from mild Covid infection, men have lower sperm concentrations and fewer sperm that are able to swim.
Professor Rocio Núñez-Calonge said that after an average of 100 days following infection there appeared to be no improvement in sperm quality and concentration, even though new sperm would have been produced in that time. Pro Núñez-Calonge said: “There have been previous studies that show semen quality is affected in the short term following a Covid infection but, as far as we are aware, none that have followed men for a longer period of time.
“We assumed that semen quality would improve once new sperm were being generated, but this was not the case. We do not know how long it might take for semen quality to be restored and it may be the case that COVID has caused permanent damage, even in men who suffered only a mild infection.”
