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.

This fund funds research National Institutes of HealthPubliated on Thursday in American Journal of EpidemiologyFor approximately a year and ending in November 2021, we tracked the data of more than 2100 women in Canada and the U.S.

Researchers found that Covid vaccinations had no effect on fertility rates, in men and women. These findings add to growing evidence. the safety of Covid vaccines.

Also, the study found that women who test positive for Covid in their 60-day period were 18% more likely to have a child during this time than those who did not.

It’s possible to have a baby as soon as you get Covid. However, it might take longer. Amelia WesselinkProfessor of Epidemiology, Boston University School of Public Health School of Public Health and co-author of the study, tells CNBC Make it.

Wesselink stated that there were no long-term effects of Covid infections on male fertility.

It is still unclear why Covid-related declines in fertility are occurring. However, it’s worth noting that fever is a common Covid symptom — and fevers are known to temporarily reduce sperm count and motility, according to the NIH.

According to Dr. Boback Berookhim of Lenox Hill Hospital, New York City’s director of male fertility, microsurgery and male covid, men with high fevers or symptomatic Covid can experience temporary declines in their sperm counts that will likely rebound in the next few months.

According to him, “Sperm Production generally requires normal body temps.”

Lenox Hill’s Director of Gynecology Dr. Adi Katz believes that inflammation from an infection could also contribute to a decrease in quality sperm. She adds that multiple studies have shown that Covid infection can impact male fertility. These effects are most noticeable in those who have fallen moderately to severe ill.

The NIH funded study found that vaccination against Covid could prevent a short-term drop in fertility in men. Wesselink said that she hopes her research will allow couples to make more informed choices about Covid vaccinations. It should also give assurance that they won’t be hurting their chances of having children.

The study involved more than 2,100 female subjects aged 21 to 45 in Canada and the U.S. between December 2020 and November 2021. Each subject was asked to answer a health questionnaire online for eight weeks before becoming pregnant. If they didn’t, they were asked to do so again for one year.

Also, participants had to answer questions about their male partner and were given the chance to invite them to take similar questionnaires. Nearly 25% did. The study found that 73% and 74% had at least received one Covid vaccine.
