In this paper we present different initiatives carried out by Spanish universities for the incorporation of the gender perspective in STEM disciplines. One of these initiatives is the collection of guides of the Vives University Network for university teaching. These guides cover the sections of objectives, contents, evaluation, learning environment, organizational modalities, teaching methods, and didactic resources with the aim of making women scientists visible in the discipline and eliminating the androcentric vision that predominates in science and engineering. In particular, we analyze the fields of engineering, mathematics, and physics. With the aim of being more than just a review of different initiatives, the paper unifies the fundamentals on which these initiatives are based. Thus, the general principles are well defined, and those aspects more related to each university and discipline particular cultures are identified. The comparison between initiatives will allow us to identify both successful strategies and resistances. Sometimes, the confluence of different events allows an action to become relevant or not. As a result, the paper can be used to effectively define the implementation strategy of the incorporation of gender perspective in STEM teaching at university level.
