Researchers from Boston University analyzed data from more than 2,000 couples trying to conceive.
"The findings provide reassurance that vaccination for couples seeking pregnancy does not appear to impair fertility," Dr. Diana Bianchi, head of the arm of the National Institutes of Health that funded the study, said in aThe study's authors say they surveyed participants — adult women up to 45 years old who are trying to conceive without the use of fertility treatments — and many of their partners every eight weeks for a year.
A statistical analysis of data collected from the participants found"no meaningful association" between couples who reported COVID-19 vaccination and the likelihood they were able to conceive, compared to unvaccinated participants. That also held true across a variety of other factors, the researchers said, including vaccination brand and different times of the year.
However, male partners who reported they tested positive for COVID-19 appeared to be associated with"a transient reduction" in the likelihood of conception within 60 days. "These findings indicate that male SARS-CoV-2 infection may be associated with a short-term decline in fertility," they said.
