Problems after infection or vaccination? Fertility study finally answers mysterious rumour

According to a US study, vaccinated people have the same chance of becoming pregnant as unvaccinated people. In contrast, men may be less fertile shortly after a Covid infection.

Boston – Some men are reluctant to get vaccinated against the coronavirus for fear of infertility. A study from the USA examined the connection between vaccination and infertility and between Covid infection* and infertility.

The result: If the man and/or woman are vaccinated, the chances of conceiving are almost the same as for unvaccinated people. After the man became infected with Covid, however, children’s wishes were fulfilled less often.

Information on the study on Covid vaccination/corona infection and fertility:

  • Number of participants: 2126 women
  • Method: Online questionnaires and studies
  • Period: December 2020/September 2021 (start) to November 2021 (end)
  • Study authors: Amelia K. Wesselink, Elizabeth E. Hatch, Kenneth J. Rothman, among others
  • Institution: Boston University
  • Source: American Journal of Epidemiology

Three quarters of the study participants had already received one or two vaccinations*. The participants were already enrolled in a study that has been running since 2013 and accompanies women who want to have children. The query of the vaccination status was part of the questionnaires.

According to the study, vaccinated women even had a slightly higher probability of becoming pregnant: They were 1.08 times more likely to become pregnant than the unvaccinated participants – which means that the probability remained almost the same.

“Our study clearly shows that the Covid-19 vaccination has no effect on the fertility of couples who want to have children,” said study author Amelia K. Wesselink. “The vaccination status does not affect the time until conception and pregnancy.” Other studies have already shown that there are no differences between mRNA vaccines (like that of Biontech*) or vector vaccines (like that of Astrazeneca*).

However, the figures from the study also show that if men became infected with the corona virus, the chance of the woman getting pregnant in the first 30 days after infection was reduced by 80 percent. According to the authors, other studies have shown that the quality of the sperm can be reduced by fever and inflammatory reactions in the body after an infection.

Up to day 60 after infection, the chances of conceiving were reduced by 18 percent, according to the study. (kat) *Merkur.de is an offer from IPPEN.MEDIA.
