This toolkit has been prepared to help organizations and governments to support the review of and update existing policies to ensure they fully engage men and boys to promote their positive roles in improving sexual and reproductive health – both their own and those of women and children. The toolkit explains why this is important and how to achieve it. It also highlights how engaging men in sexual and reproductive health and rights and HIV policies, is not simply a goal in its own right, but can help move towards the goal of gender equity.
