(Gray News) - There is growing evidence that there is no connection between COVID-19 vaccinations and fertility issues.

Researchers from Boston University and other institutions across the country looked at data on more than 2,000 women and their partners from the United States and Canada who were trying to conceive from 2020 to 2021.

The study was originally published in the American Journal of Epidemiology.

Nearly 75% of the women and their partners had received at least one dose of a COVID-19 vaccine.

Researchers concluded that the vaccinations do not impair fertility in either men or women.

However, couples in the study did have lower chances of conception if the man had been infected with COVID-19 within the past 60 days, which indicates the virus could affect male fertility in the short term.

More research is needed on that, but according to National Institute of Health, fever is known to reduce sperm count, and fever is a symptom of COVID-19.
