COVID Vaccine and Fertility: Separating Fact from Fiction

False claims linking COVID-19 vaccines to fertility issues have raised concerns among some considering vaccination. However, major health organizations emphasize that vaccines do not affect fertility. The mRNA and viral vector vaccines provide instructions for cells to make harmless spike proteins – they do not alter DNA or sex cells. This thorough exploration of multiple studies confirms COVID vaccine and fertility are safe for those trying to conceive or pregnant. Get the facts to make an informed decision about your health.

Do COVID-19 Vaccines Impact Fertility?

Breastfeeding Mother

Multiple clinical studies and real-world data show the Pfizer, Moderna, and Johnson & Johnson COVID-19 vaccines do not affect fertility in males or females. Here is an overview of evidence confirming the vaccines’ safety:

  • The vaccines do not interact with reproductive cells since they work with the immune system, not sex cells. The mRNA and viral vector vaccines never enter the nucleus where DNA is kept.
  • Clinical trials with thousands of participants that led to FDA authorization found no differences in pregnancy rates between vaccinated and placebo groups. Rates of miscarriage, menstrual cycle changes, birth defects, and babies’ development were also similar.
  • Data from over 200,000 vaccinated people shows rates of infertility, miscarriage, menstrual changes, conception, and pregnancy complications equal unvaccinated rates.
  • Leading medical organizations like the CDC, the American College of Obstetricians and Gynecologists, and the National Institutes of Health confirm that vaccines do not cause infertility or harm pregnancy. This conclusion is supported globally.
  • Real-world data on tens of thousands of vaccinated pregnant people shows they have the same rates of pregnancy loss as the general population. The vaccines provide a strong maternal and fetal health benefit.

In summary, clinical trials, medical organizations, real-world analysis, and reproductive experts find the COVID-19 mRNA and viral vector vaccines have no link to fertility issues. Get vaccinated with confidence.

Safety for Those Planning Pregnancy – COVID Vaccine and Fertility

Couples trying to conceive have two key considerations regarding COVID-19 vaccination:

  1. Timing Vaccination Relative to Conception Efforts
  • No evidence indicates any need to delay pregnancy after vaccination. Many conceived the cycle of or soon after vaccination with no issues.
  • Leading OBGYN groups confirm it is safe to get vaccinated any time before conception or during your fertility treatment cycle. There is no reason to alter efforts to become pregnant.
  1. Protecting Fertility and Future Pregnancy from COVID-19 Risks
  • Contracting COVID-19 may raise risks to male and female fertility and endanger pregnancy. Vaccination is the best protection.
  • In males, COVID-19 infection can harm sperm and testes which may temporarily reduce fertility. The vaccine prevents this.
  • In females, COVID-19 may impede ovarian response and egg quality which could temporarily lower fertility. Vaccination prevents this possibility.
  • Contracting COVID-19 while pregnant significantly raises risks of complications for both mothers and babies. Vaccination greatly reduces these life-threatening risks.

The Bottom Line: All couples trying to conceive should get vaccinated against COVID-19. The vaccines provide the best protection for fertility and pregnancy.

Vaccine Safety During Pregnancy

Multiple studies with tens of thousands of pregnant people show the COVID-19 vaccines (especially mRNA) are safe during pregnancy and provide a strong health benefit:

  • The vaccines show no increased risk of miscarriage, birth defects, preterm birth, or baby complications compared to unvaccinated pregnant people.
  • However, contracting COVID-19 while pregnant does raise risks of preterm birth, maternal mortality, and fetal complications. The vaccines greatly mitigate these risks.
  • Antibodies generated from the vaccines transfer through the placenta to the fetus, helping protect vulnerable newborns who cannot yet be vaccinated themselves.
  • Over 100,000 pregnant people have been safely vaccinated in the US with no concerning patterns according to the CDC. The benefits far outweigh any potential risks.
  • Este declaration of resounding support for vaccination as the preeminent and infallible modality of choice, targeting individuals who currently bear the mantle of pregnancy or stand at the precipice of contemplating conception, is staunchly championed by esteemed maternal health institutions, prominently including the venerable American College of Obstetricians and Gynecologists (ACOG).It is paramount for those who are currently pregnant and have not yet received the vaccine to seriously contemplate taking this precautionary step. By doing so, you are not only safeguarding your own health but also extending this protective shield to the invaluable life developing within you, thus guaranteeing a safer passage for both yourself and your unborn child. Boosters provide additional protection against variants. The vaccines are well-tested and safe during pregnancy.

Vaccine Safety for Breastfeeding Mothers


The science also confirms COVID-19 vaccination is safe for breastfeeding mothers and provides a benefit:

  • The vaccine ingredients are rapidly broken down and do not enter breast milk at concerning levels that would impact infants. Clinical trials found no risks.
  • Maternal vaccination enables antibodies to transfer through breastmilk, adding protection for vulnerable babies during the pandemic.
  • Leading health organizations support vaccination while breastfeeding, including the World Health Organization, American Academy of Pediatrics, and Society for Maternal & Fetal Medicine.
  • Research detected robust antibodies in the breastmilk of vaccinated mothers, signaling a high potential to protect nursing infants from COVID-19.

Breastfeeding parents should feel secure getting vaccinated per all evidence and guidance. Not only is vaccination safe, it provides nursing babies with additional protection from COVID-19 at no risk.

 FAQs About Covid Vaccine and Fertility:

Here are answers to some frequently asked questions about the COVID-19 vaccine and fertility:

Is it safe to get vaccinated if you are undergoing IVF or fertility treatments?
Answer: Yes, leading reproductive medicine groups confirm it is safe to get vaccinated against COVID-19 at any stage of infertility treatment without impacting fertility outcomes.

When should you get vaccinated relative to your menstrual cycle if trying to conceive?
Answer: The vaccines have no link to menstrual changes or fertility, so you can receive them at any time during your cycle. Maintain your conception efforts as normal.

Can COVID-19 vaccines lead to birth defects if vaccinated during early pregnancy?
Answer: No, data on thousands of people vaccinated during pregnancy shows rates of birth defects equal to the unvaccinated population. There is no increased risk.

Do the vaccines affect male or female fertility or sexual function?
Answer: There is no evidence that the COVID-19 vaccines impact male or female fertility, reproductive organs, hormone levels, or sexual performance and function.

Do mRNA or viral vector vaccines interact with DNA to influence genetics?
Answer: No, the vaccines never enter the cell nucleus where DNA is kept. They provide instructions for cells to make spike proteins only and do not alter DNA.

  • Clinical trials and real-world data find no link between COVID vaccine and infertility, pregnancy loss, or birth complications.
  • Leading maternal health organizations strongly recommend vaccination for optimal safety for those planning pregnancy or already pregnant.
  • Vaccination provides the best protection for fertility and pregnancy by preventing COVID-19 infection and transmission.
  • Getting vaccinated is regarded as safe at any stage—whether it’s prior to, during, or subsequent to pregnancy while breastfeeding, or during fertility treatments.

Base your decision on reliable and accurate data to choose what’s best for you. If considering children, vaccination provides strong maternal, fetal, and neonatal protection from the worst COVID-19 outcomes. Discuss any specific questions or concerns with your healthcare providers.
