VOICED : Ciclo menstrual puede retrasarse levemente tras la vacuna anticovid, según estudio

A U.S. study found that COVID-19 vaccinated women experienced a slight menstrual delay of nearly a day compared to unvaccinated women. Conducted on nearly 4,000 individuals and published in Obstetrics and Gynecology, the study noted no change in bleeding days. The minor cycle length increase is not clinically significant, as changes under eight days are normal per the International Federation of Gynecology and Obstetrics. The study may help counter misinformation about vaccines and menstrual cycles on social media. Researchers suggest the immune response to the vaccine, known to interact with the reproductive system, may cause this small change.
