This document provides an overview of sexual and reproductive health and rights issues that may be important for the human rights, health and well-being of adolescents (aged 10–19 years) and the relevant World Health Organization (WHO) guidelines on how to address them in an easilyaccessible, user-friendly format. The document serves as a gateway to the rich body of WHO guidelines, and as a handy resource to inform advocacy, policy and programme/project design and research. It aims to support the implementation of the Global Strategy for Women’s, Children’s and Adolescents’ Health 2016–2030 (1), and is aligned with the WHO Global Accelerated Action for the Health of Adolescents (AA-HA!) as well as the WHO Operational Framework on Sexual Health and Its Linkages to Reproductive Health (2,3).
