The study, which was based on sperm samples taken from young men up to the age of 30, found that there was no decrease in the amount or quality of sperm recipients of the second dose of the vaccine. Further research

With the start of marketing of Pfizer and Modern’s corona vaccines in early 2021, many were afraid to accept them as not all information on long-term effects was known. On social media, a lot of unfounded and false information has been spread about problems that the vaccine can cause to various systems in the body, including the quality and quantity of a man’s sperm. A new study from the Institute of Human Reproduction in Chicago tries to answer the question of whether there is such an effect on man, and his findings are reassuring.

According to the study, which was conducted on a fairly small sample of 45 men between the ages of 31-25 with no early fertility problems, sperm count and quality did not drop after receiving the second dose of Modern or Pfizer vaccine. The study was published Thursday in the medical journal JAMA.

In order to achieve valid results, the researchers took a semen sample from the participants before receiving the first dose of the vaccine, and then a second sample 70 days after the second dose of the vaccine. However, one of the limitations of the study is the young age of the participants, and further studies will need to examine the effect of the vaccine on the fertility of men at a later age.

“We now have proof that the risk of male infertility being harmed by the vaccine is very low,” said Dr. David Cohen, one of the directors of the institution where the study was conducted.
