Immunization and Fertility

Do COVID-19 Vaccines cause infertility?

• There is NO LINK between COVID-19 vaccines and infertility to date

  • Current evidence based on three IVF subgroups (see below) analysis showed NO DIFFERENCE in pregnancy success rates

    • Antibodies from having been vaccinated against COVID-19

    • Antibodies from having a recent infection with the virus that causes COVID-19

    • No antibodies from either having a recent infection with the virus that causes COVID-19 or from having been vaccinated against COVID-19

  • Comparing sperms from men who received COVID-19 vaccines to those who did not, researchers found NO significant changes in these sperm characteristics after vaccination.

• Bottom line: COVID-19 vaccines do not cause infertility in men or women. Pregnant or thinking about getting pregnant, get vaccinated to reduce the risk of complications from COVID-19.

Current recommendations for vaccines for female infertility patients:

• There is currently no evidence showing that ANY vaccines, cause fertility problems (problems trying to get pregnant) in women or men

• Vaccinations before or during pregnancy protect women from potential serious illness and allow for immunity to pass to the newborn

• The mother’s immunity is transported by immunoglobulin (IgG) antibodies to the baby, this occurs throughout gestation and increases markedly right before the baby is born (during the last 4 to 6 weeks of gestation)
