Proving a negative is always a difficult challenge. But for over a year now this is what the providers of vaccines have been trying to do. Governments, health authorities and manufacturers have trying to squash the unfounded claims on social media that the COVID-19 vaccines cause infertility.
A new study from Boston University, US appears to have finally laid the issue to rest. The researchers found that COVID-19 vaccination does not appear to impair fertility in either men or women. However, they did find that men who were infected with the coronavirus experienced short-term infertility.
Covid-19 vaccination unrelated to fertility
Dr. Amelia Wesselink, Lead Scientist said, “Many reproductive-aged individuals have cited concerns about fertility as a reason for remaining unvaccinated. Our study shows for the first time that COVID-19 vaccination in either partner is unrelated to fertility among couples trying to conceive through intercourse. Time-to-pregnancy was very similar regardless of vaccination status.”
The conclusions were based on an analysis of 2,126 women in the US and Canada who were trying to conceive. The women were followed from preconception through to the six months after delivery. Analysis of the results found:
● Nearly identical fertility rates among female participants who received at least one dose of a COVID-19 vaccine and unvaccinated women
● Similar fertility parameters for male partners who had received at least one dose of a COVID-19 vaccine and unvaccinated male partners.
Correlation between vaccination and infertility
This is a powerful study because it was both large and designed to find a . The fact that no such correlation exists is further reassurance, on top of all the other reassuring indicators, that the vaccine will not impact on women seeking to build families.
But the researchers also found a different, equally disturbing, issue: infection with the coronavirus does indeed appear to cause temporary infertility in men. Men who tested positive for COVID within 60 days of a given cycle had reduced fertility compared to men who had never been infected by the coronavirus or men who tested positive more than 60 days prior.
Men had reduced fertility after Covid-19 infection
This finding supports previous research that indicates COVID-19 infection in men resulted in poor sperm quality and other reproductive problems. In other words, if anything, the vaccine would appear to be conducive to fertility in men when it prevents infection by the coronavirus.
Dr. Diana Bianchi, Director of the National Institutes for Health, who funded the study stated, “The findings provide reassurance that vaccination for couples seeking pregnancy does not appear to impair fertility. They also provide information for physicians who counsel patients hoping to conceive.”
