    The creation of a vaccine to face the COVID-19 pandemic, led to an information gap on possible alterations of the menstrual cycle. The objective was to verify the possible alterations that could have been generated in the menstrual cycle of women, after the inoculation of the vaccine against COVID-19. A systematic review was carried out in the Medline, Medline Complete, LILACS, CINAHL and ScIELO bibliographic databases, using the descriptors“Women”,“Woman”,“Fertile period”,“Vaccination”, “Mass vaccination”,“Immunization”,“COVID-19 vaccines”,“SARS-CoV-2 infection”,“COVID-19”,“Menstrual cycle”,“Menstruation”, “Endometrial cycle”,“Dysmenorrhea”and“Menstruation disturbances”. Using the PRISMA protocol, of the 319 articles located, 17 were included in the analysis. Most of the studies mainly included the Pfizer, Moderna, AstraZeneca and Johnson&Johnson/ Janssen vaccines with one to three doses administered. The percentage of altered menstrual cycles ranged from 8.0% to 77.8%, and the most frequently reported alteration was the length of the menstrual cycle, which occurred from 0.3 to 12 days late in menstruation. All the studies refer to changes in the menstrual cycle with different prevalences, with and without statistical significance; however, the same studies also conclude that these alterations are reversible and in a short period of time. © 2023 Sociedad Chilena de Obstetricia y Ginecologia.
