COVID-19 vaccines do not cause lower sperm counts
Daily MailCOVID-19 vaccines do not reduce the sperm count or quality of men, and may even increase the amount of semen they produce, a new study suggests. They did not find any sperm count reductions for men who had received either one or two doses of the Pfizer-BioNTech or Moderna coronavirus vaccine, and the final mean and median sperm counts even increased. Conspiracies that the COVID-19 vaccines cause decreased sperm count or infertility in men have spread on social media as part of a flurry of vaccine disinformation While COVID-19 vaccines may not have much effect on sperm, the virus that causes the disease does. Along with claims that the vaccines cause lower sperm count in men, and by virtue reduced fertility or flat out infertility, many have also made the false claim that the vaccine causes infertility in women.
