This paper builds upon a previous version jointly written by Countdown 2030 Europe and Action for Global Health. It seeks to show how the World Health Organisation (WHO) definition of universal health coverage (UHC) and its vision of the social determinants of health underpinning UHC relate to sexual and reproductive health and rights (SRHR) and the enabling factors which affect SRHR. It argues that UHC cannot be truly achieved without addressing SRHR as a matter of priority, and that an approach to UHC which is grounded in human rights is critical for making progress on SRHR. It acknowledges that, some aspects of SRHR continue to be deprioritised and will continue to require ongoing and additional focus and activism. It concludes with some key messages and recommendations on what it means to achieve universal access to SRHR.
