‘Absolutely no evidence’ COVID vaccines affect fertility

There is “absolutely no evidence” that COVID-19 vaccines can affect the fertility of women or men, says new expert guidance.

The guidance, published by the Association of Reproductive and Clinical Scientists and the British Fertility Society, comes amid concerns that misinformation that has been circulating online about COVID-19 vaccines and fertility may be putting some women off having the vaccine.

The guidance refutes any link between the vaccines and fertility. “There is absolutely no evidence, and no theoretical reason, that any of the vaccines can affect the fertility of women or men,” it says. People of reproductive age should get a COVID-19 vaccine when they receive their invitation, including people who are trying to have a baby or thinking about having a baby in the future, the guidance says.

People undergoing fertility treatment can be vaccinated during treatment, but may wish to consider the timing given the potential side effects in the few days after vaccination. “It may be sensible to separate the date of vaccination by a few days from some treatment procedures (for example, egg collection in IVF), so that any symptoms, such as fever, might be attributed correctly to the vaccine or the treatment procedure,” says the guidance.

People may start their fertility treatment immediately after being vaccinated, unless they wish to have a second dose before pregnancy, it adds. The guidance also states that those who are donating their eggs or sperm for the use of others can still have a COVID-19 vaccine.
