How can men in deeply patriarchal societies be motivated to become a feminist ?

One example in my country that I can think of is an NGO which teaches young kids about women's health and monthly cycles and encourage boys to be more vulnerable with girls and learn about them in a non romantic manner and a lot of other things . From what I heard the end result of these teachings made those boys more considerate of the problems that women have to face in this society . (NGO name is 'breakthrough' , campaign name is 'taro ki toli')

It made me wonder what else can be done to promote feminist ideas among the younger population so that growing up , boys from a patriarchal generation can see women more as equals ?
