This work aims to understand the perception of instructors about the teaching of trans people in health during the medical course, considering how training can influence the treatment, reception and access of these people in primary care. Twenty four interviews were conducted with professors from a Faculty of Medicine in Curitiba, Paraná, Brazil. The study of the interviews was based on the Content Analysis of Moraes (1999). It defined 5 categories of analysis: "conceptual dimension", "biological dimension", "social dimension", "pedagogical dimension" and "skills development". It is possible to conclude that the pedagogical approach during graduation presents many flaws, being necessary to show the relevance for the medical community in the sense of inserting the theme in the university's curriculum.
