Scientists from the Texas Child Family Fertility Center have found that vaccinating women against COVID-19 does not affect their ovarian reserve, that is, the number of eggs that can participate in the fertilization process. Research published JAMA Network Open.
The study included nearly a thousand women undergoing infertility treatment at the Texas Center. Of these, 836 were not vaccinated and 138 were vaccinated from Pfizer-BioNTech, Moderna or Janssen.
The scientists evaluated the participants’ ovarian reserves using ultrasound (AFC score) and anti-Müllerian hormone levels. Pre- and post-vaccination studies against COVID-19 were conducted. Analysis of the data showed that vaccination did not affect any indicators, but ovarian reserve was largely dependent on age.
Evidence suggests that COVID-19 vaccination is not associated with changes in ovarian reserve, which has been confirmed by previous studies. However, given the small number of patients receiving the vaccine, the authors call for larger studies.
