'One Man Can': shifts in fatherhood beliefs and parenting practices following a gender-transformative programme in Eastern Cape, South Africa.

'One Man Can' (OMC) is a rights-based gender equality and health programme implemented by Sonke Gender Justice in South Africa. It has been featured as an example of best practice by the World Health Organization, UNAIDS, and the UN Population Fund, and translated into nearly a dozen languages and implemented all across Africa. South Africa has strong gender and HIV-related policies, but the highest documented level of men's violence against women in the world, and the largest number of people living with HIV.
