Our study aimed to evaluate the gender awareness in medicine of students in a medical school in Istanbul. The population of this descriptive study consists of 1523 medical students studying at a state university in Istanbul in the 2020-2021 academic year. The study took place between February and March of 2021. The study was conducted with 484 participants. The data were collected using a questionnaire for sociodemographic features and the Nijmegen Gender Awareness in Medicine Scale (N-GAMS) filled out by the participants. Statistically, p<0.05 was considered as the level of significance. Ethics committee approval was obtained from the relevant institution before the study. Most of the participants were female (n=319, 65.9%) and the participants' mean age was 21.8±2.1 years. Multivariate tests showed differences in gender role ideology towards patients and doctors according to the gender of the participants and the working situation of their mothers. Also, significant sex-related differences were found in gender sensitivity. As compared to others, male students or those whose mothers were unemployed held slightly more gender stereotypes towards patients and doctors. As shown in our results, the participants were stereotyped in gender role ideology and suboptimal gender sensitivity. Gender stereotypes can be prevented through gender-sensitive medical education. More studies, particularly qualitative studies, are needed on this subject to examine the students' gender awareness in medicine and perception levels related to their sociodemographic characteristics in more detail and to determine the measures that can be taken to solve the problem.
