From the patriarchal gender culture, inequities emerge that are manifested in social and labor relations. Women still lead to disparities in participation and production of a scientific nature around the world, being more evident in technological areas. This paper presents an exploratory descriptive analysis of postgraduate teaching in Computer Science in Brazil, addressing aspects of representativeness by gender in that area. The results revealed that, despite the programs to encourage the participation of women in the areas of technology, in the last 15 years there has been a significant reduction in the proportionality of women in postgraduate teaching in Computer Science in Brazil. In addition, it opens discussions on issues of interest related to factors such as the predominant age group of women in the area, 40-69 years, suggesting research on the impact of other factors on active participation, such as motherhood, for example.
