Pfizer’s novel Covid-19 vaccine leads to lower levels of fertility in men, according to a new peer-reviewed study. The paper, which has been accepted for publication in the journal Andrology evaluated the impact of the experimental Covid-19 injections on sperm motility and concentration and found that, three months after vaccination, semen concentration was reduced by 15.4%.

… The semen testing, which was completed 150 days following vaccination, showed that post-vaccination levels remained lower than pre-vaccination levels, although there was some improvement over time. The men were not tested following the third and fourth injections; further damage to sperm motility and counts are therefore possible following subsequent doses and no long-term fertility data are currently available.
