The Ethics Committee approved the study and all participants included were of legal age and gave their express consent. A general descriptive analysis of the data obtained and the relationships between the variables studied were conducted: experiences with sexual health, attitudes toward sexuality, knowledge, and satisfaction with the SE received. Finally, a Latent Class Analysis (LCA) was performed, and the influence of sociodemographic factors on the composition of the different student profiles obtained was measured using the chi-square test.The majority of the sample was composed of undergraduate students (93.2%), women (67%), and heterosexuals (80%), with an average age of 21. Over half of the participants identified as Christians (51%) and had not yet left the family home (53%). The Internet was the source of information that most influenced the SE received, and family was the least. Upon completion of their studies, around half of the students (47.7%) acknowledged that they still lacked knowledge regarding SE.Type of career, gender, sexual orientation, and religious affiliation were the sociodemographic factors that influenced opinions and the acceptance or rejection of myths towardssexuality (p<0.05), as well as knowledge about sexual health (p<0.05). A significant relationship was observed between expressing favourable opinions, rejecting myths, and showing greater knowledge about sexual health (p<0.05).Regarding the ACL, three profiles of students were observed regarding their opinions on sexuality: unfavourable (17%), intermediate (68%), and favourable (15%). As for the myths about sexuality, four profiles were identified: indifferent (31%), those who accept the myths (2%), intermediate (48%), and those who reject them (20%). Gender, sexual orientation, religious status, and type of education influenced the composition of all profiles (p<0.05).Findings highlighted the need to address gender, sexual diversity, and religiosity, as well as the type of career pursued, in sexual education programs during the university period. The prevalence of indifference and limited critical engagement suggests a pressing need for more inclusive and evidence-based approaches in university contexts.
