COVID-19 virus, not vaccines, may affect fertility

Many people, especially those of childbearing age, are still reluctant to get vaccinated in the face of the spread of COVID-19. Indeed, they are worried about the fact that vaccines against COVID-19 can affect fertility.

Faced with this situation, the Boston University School of Public Health (BUSPH) conducted a study to examine the relationship between vaccination, fertility and COVID-19 infection. The analysis was based on the results of surveys conducted between December 2020 and September 2021 among 2,126 Canadian and American women, vaccinated and unvaccinated.

Several variables were considered during the investigation such as lifestyle, medical factors and partner characteristics, age, socio-economic status, pre-existing health conditions, occupation and stress levels . The results of the analysis have been published in the journal American Journal of Epidemiology.

Getting vaccinated against COVID-19 has no effect on fertility

According to Dr. Lauren Wise, professor of epidemiology at BUSPH, the data collected from the surveys provided reassuring evidence. Vaccination against COVID in either partner does not affect the fertility of couples trying to conceive.

The study found that there was no link between fertility and vaccination. Regardless of the type of vaccine chosen or the number of doses of the vaccine injected, the vaccinated person remains fertile.

The relationship between COVID-19 and male fertility

On the other hand, the study showed a link between male fertility and COVID-19 infection. Being infected with the COVID-19 virus has a temporary negative effect on fertility in men.

According to the BUSPH team’s finding, men who tested positive for COVID-19 in the last two months of a given menstrual cycle had lower fertility compared to men who had never been tested. positive, or those that were positive more than 60 days ago. Other studies have also shown that the COVID-19 virus can affect the penis and testicles.
