Recent Study Put An End To Rumours Of Covid-19 Vaccination Leads To Infertility

The study posted in the American Journal of Epidemiology claims that Covid-19 vaccination does now no longer seem to affect fertility.

The prospective cohort study of partners who are trying to conceive observed no affiliation between Covid-19 vaccination and the possibility of conception per menstrual cycle in female or male companions who received the Johnson & Johnson, Moderna, or Pfizer-BioNTech vaccinations.

The findings in contrast showed that Covid-19 infection could temporarily reduce fertility among males, which can be avoided through vaccination.

Dr. Amelia Wesselink, research assistant professor of epidemiology at BUSPH and study lead author stated that many reproductive-aged people have concerns, as a reason about fertility for staying unvaccinated.

She further said that for the first time study shows Covid-19 vaccination is not related to fertility among the partners who are trying to conceive through intercourse. Pregnancy time was the same despite vaccination status.

They should embrace instead of keeping away from vaccination because there is evidence about the danger of infection caused by Covid-19 to pregnant women. And there is no reason to believe that the vaccination poses any risk to women who are trying to conceive.

Compare to other people of the same age pregnant women get sicker when they get Covid-19. Andy, they are more likely to experience premature delivery. It is important to prevent it as the Covid-19 disease effect on pregnancy is real.

Wesselink with colleagues analyzed the survey data on Covid-19 vaccination and its infection, and the possibility of conception per menstrual cycle in female and among the male participants in Pregnancy Study Online PRESTO at BUSPH, which is NIH funded research that enrolls women who are trying to conceive and follows them from preconception until six months after the delivery.

In the United States and Canada 2126 women participants were included who provided the information on medical factors, characteristics, sociodemographic, and lifestyle of their partners from Dec 2020 to Sep 2021, and they were followed in the study until Nov 2021.

The researchers calculated each fecundability, using participants' self-reported dates. Female participants' fertility rates who received at least one dose of the vaccination were nearly the same as unvaccinated female participants.

Male partner's fecundability was also same who had received at least one dose of vaccination when compared with unvaccinated participants. Infertility history, occupation, the brand of vaccine, the number of vaccine doses, and the geographic region were also considered in additional analyses, which indicated no effect of the vaccine on fertility.

Though Covid-19 infection now no longer strongly related to fertility, men who were tested positive within 60 days cycle had reduced fertility compared to men who were never tested positive or those who tested positive before 60 days. The data support previous studies which have related Covid-19 infection in men with poor quality of sperm and other reproductive dysfunction.

Dr. Lauren Wise, professor of epidemiology at BUSPH and senior author of the study stated that the data provide proof that the Covid-19 vaccine does not affect fertility among partners who are trying to conceive.
