Men have a critically important role to play in supporting women from different backgrounds to move into leadership roles. Indeed, it is necessary work for those in positions of privilege to challenge processes that result in inequitable gender outcomes in health leadership. We present the resources that have been compiled into a toolkit for men to support more inclusive health leadership and transformative systemic change. A three-step process was undertaken to search, select, and curate leading evidence-informed practices. Three key clusters of resources in the toolkit address why men’s actions are necessary, what leading actions entail, and the importance of mentorship and sponsorship. Change will require more than shaping the individual attitudes and behaviours of men in leadership positions. Attention to gender and other forms of inequity need to be embedded into the structures, processes and outcomes of teams, organizations, and systems and evaluated for process.
