A new study shows that Covid-19 vaccines don’t impair fertility in men or women — but a Covid infection could potentially affect a man’s fertility for up to 60 days.
Research funded by the National Institutes of Health and published on Thursday in the American Journal of Epidemiology tracked data from more than 2,100 women and some of their partners in the U.S. and Canada for roughly a year, ending in November 2021.
It found that getting vaccinated against Covid had no discernable effects on fertility rates in either men or women, adding to a growing body of evidence regarding the safety of vaccines.
The study also found that men who tested positive for Covid within 60 days of their partner’s menstrual cycle were 18% less likely to conceive during that cycle, compared with men who had not tested positive.
