COVID vaccine does not cause infertility, Israeli study finds

January 5, 2022 – Ever since the Pfizer-BioNTech vaccine was approved, there have been rumors that it could affect women’s fertility. Some anti-vaccine activists have embraced these claims.

COVID vaccines do not affect the functioning of the ovaries or the fertility of women in general, according to a study from Sheba Medical Center in Tel Hashomer.

The research, published in the journal Human Reproduction, was conducted by Sheba’s Women’s Department. Dr Aya Mohr-Sasson led the study, along with Professor Jaron Rabinovici, deputy director of the Josef Buchmann Gynecology and Maternity Center.

The study looked at levels of anti-Mullerian hormone (AMH) – levels of which indicate a woman’s ovarian reserves – in some 200 subjects of childbearing age. A total of 129 women completed all stages of the study.

The women were tested before receiving the first doses of the Pfizer-BioNTech COVID vaccine and again three months after the first dose. In the three-month interval, the subjects received the second dose of the vaccine.

According to the study, the vaccine had no adverse effects on the women’s ovarian function and their AMH levels did not change. Hormone levels remained stable even when subjects were analyzed by age group.

Sheba Medical Center is currently conducting a follow-up study on girls ages 12 to 18, as well as following up the initial group of subjects after receiving booster shots.

Rabinovici said: “One of the concerns since the COVID vaccine came out was that it could cause infertility. The study shows that the vaccine does not affect a woman’s fertility. As for the future, we know that vaccine side effects are short-term, not long-term.
