COVID-19 Vaccines Don’t Cause Infertility or Harm Pregnancy Chances

Having a COVID-19 vaccine doesn’t impact a couple’s chances of becoming pregnant—but skipping the shots and landing a coronavirus infection might reduce male fertility.

Those are the findings in a paper published in the American Journal of Epidemiology by researchers at the Boston University School of Public Health. In a study of couples trying to conceive, they found no association between COVID-19 vaccination and the likelihood of conception in female or male partners who received the Pfizer-BioNTech, Moderna, or Johnson & Johnson vaccines.

While COVID-19 infection was not strongly associated with fertility, men who tested positive for COVID within 60 days of a given cycle had reduced fertility compared to men who never tested positive, or men who tested positive at least 60 days prior.
