Objective: Evaluate the prevalence, authorship and reliability of educational fertility-related information shared on Brazilian Instagram measured by the DISCERN instrument Methods: This cross-sectional study analysed public fertility-related educational Instagram posts published in March 2021 related to the following hashtags: #infertility, #ivf #endometriosis, #tryingotconceive, #maternity, #humanreproduction, #pregnancy, #invitrofertilization, #assistedreproduction, #pregnant, #difficulttogetpregnant. Educational posts were evaluated using the DISCERN tool. Authorship was divided into healthcare professional (HCP) or lay people (LP). Results:The majority of the 37 analyzed posts were authored by HCP (n=33;89,2%) 24 of which were doctors, 5 fertility clinics, 4 allied HCP, one magazine and 3 LP. Most posts (n=15) were about fertility treatments; other topics included information about diseases, exams and diagnosis. Mean Discern analysis for each question was: (1) Are the aims clear? 4,86;(2.) Does it achieve its aims?4,75.(3.) Is it relevant? 4,47.(4.) Is it clear what sources of information were used to compile the publication (other than the author or producer)? 1,58. (5) Is it clear when the information used or reported in the publication was produced?1,59. (6.) Is it balanced and unbiased?1,59. (7) Does it provide details of additional sources of support and information?1,04. (8) Does it refer to areas of uncertainty?1,39. Conclusions: Although doctors authored most posts which clearly stated the aim and relevancy, important issues such as source of information used and details about additional sources of support and information were not available. The posts here analyzed failed to be balanced and unbiased and did not inform about possible areas of uncertainty.
