A recent study by the US National Institutes of Health showed that vaccination against Covid-19 does not affect the chances of reproduction.
In the study, which was carried out on more than 2,000 couples, researchers found no differences in the chances of pregnancy if one of partners was vaccinated compared to unvaccinated couples, according to the results published Thursday in the American Journal of Epidemiology.
However, the study found that couples’ chances of reproduction are slightly reduced if the male partner is infected with SARS-CoV-2 within 60 days of the menstrual cycle, indicating that COVID-19 can temporarily reduce male fertility.
A total of 2,126 females from the United States and Canada participated in the study from December 2020 to September 2021 and completed questionnaires every 8 weeks on social demographics, lifestyle, medical factors, and partner information.
The researchers found no significant differences in pregnancy rates per menstrual cycle between unvaccinated and vaccinated couples, where at least one partner received at least one dose of the vaccine.
Diana Bianchi, director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which funded the study stressed that “the results reassure couples seeking reproduction that vaccination does not appear to impair fertility,”.
