The COVID-19 vaccine does not harm sperm. There is research

Men do not need to be afraid of the COVID-19 vaccine. Studies have shown that neither the number nor the quality of sperm dropped after vaccination. The research carried out concerned the Pfizer and Moderna vaccines, but the scientists suppose that the other preparations also had no effect on fertility and announce further studies.

1. A study by scientists from the University of Miami (USA) used semen samples from 45 men aged 25 to 31
2. There were no changes in semen parameters after two doses of mRNA vaccine
3. Other studies have shown that the virus can affect sperm and cause fertility problems, but more research is needed

The Pfizer and Moderna vaccines do not harm fertility

The information disseminated on social media has not been confirmed. The vaccine does not harm your fertility. This is the result of a study by scientists at the University of Miami, published in “JAMA (Journal of the American Medical Association)”, a journal published by the American Medical Association. According to the study, sperm count and quality did not change in healthy young men after receiving the first and second doses of the Pfizer or Moderna vaccine.

The study used semen samples from 45 men aged 25 to 31 who had been pre-screened to make sure they had no fertility problems. Samples were taken prior to the first injection of mRNA vaccine and then 70 days after the second dose. Later semen was examined to determine the volume, concentration, motility and total sperm count.

– We did not find any changes in semen parameters in the young healthy men we studied, and who received both doses of the mRNA vaccine, said study author Dr Ranjith Ramasamy of the University of Miami.

Johnson & Johnson and AstraZeneca, which are not based on mRNA, were not tested in the study. But Dr. Ramasamy thinks that for the rest of the vaccines, the results should be similar, despite the difference in structure.

COVID-19 and fertility. The vaccine does not, but the virus affects sperm?

The SARS-CoV-2 virus itself can be harmful to the male reproductive system, according to a study by German scientists, in which, compared with healthy men, patients with COVID-19 showed an increase in inflammation and oxidative stress in sperm. But specialists advise caution in interpreting these results.

1. How does COVID-19 affect male fertility and sperm quality?

According to Allan Pacey, professor of andrology at the University of Sheffield (UK) and editor-in-chief of the journal Human Fertility, who has been following the issue for several months, it is yet to be confirmed whether the coronavirus actually affects fertility. This is possible because the ACE2 receptors (a human enzyme that the virus protein attaches to), which the virus uses to access, for example, lung tissue, are also found in the testes. However, Professor Pacey emphasizes that drugs used to treat COVID-19 can also affect sperm count and quality, so more research needs to be done to make sure that the virus is causing this effect.
