Most universities are working committedly towards achieving the Sustainable Development Goals (SDG). The University of Alicante (UA) (Spain) has designed a series of strategies to help crystallize its aims within these goals, including those related to gender equality (SDG 5). Given the context, the aims of this study are (1) to find out whether teachers integrate SDG 5 into their teaching and, if so, what strategies they use, (2) to analyse how they perceive the effects of this and what factors help or hinder the process, and (3) to check for possible differences in these perceptions according to sex and faculty. Some 310 teachers from all the UA faculties participated. A descriptive and comparative analysis was performed, as was a content analysis. Half of the participants were found to be implementing these strategies, with women in general and teachers from the Faculty of Humanities in particular appearing to be most aware of the subject. However, only a minority applied them on a mainstream basis. The most used strategy was inclusive language. Other strategies, such as reflecting on equality, promoting equal participation, visibilizing women in different areas of knowledge, equal treatment of students and gender research, were also present in their narratives but to only a very small degree. Improved professional development for teachers and greater student awareness of gender issues were identified as positive effects of incorporating these strategies. Participants also felt that low awareness and a lack of time and training were obstacles to the process. Universities should therefore establish specific institutional policies aimed at integrating SDG 5 as a quality indicator. Training programmes should be redesigned to take into account a more practical approach, the type of learning (classroom, online or mixed), and subsequent follow-up in the classroom to guarantee effective integration.
