The United Nations Special Programme of Research, Development and Research Training in Human Reproduction, known as the Human Reproduction Programme or HRP, has been providing the world with research findings and guidance on sexual health and reproduction (SRH) for more than half a century. This annual report highlights the programme’s key achievements in 2023, and points to major ongoing research that will be completed in the next few years.

In response to the close link between economic and population issues recognized by the United Nations in 1957, the World Health Organization (WHO) was prompted to address the concerns of developing nations dealing with slow economic growth and high population growth by 1964. Establishing the Human Reproduction Unit in 1965, WHO outlined its strategy in 1965, acknowledging the repercussions of population changes on health conditions. A pivotal development occurred in 1970 when global organizations convened to discuss a research program on human reproduction, leading to the creation of the Expanded Programme of Research, Development, and Research Training in Human Reproduction (HRP) in 1971. The HRP, with its scientifically authoritative and neutral methods, significantly contributed to the development of contraception methods, which are still in use today. Additionally, the program played a role in disseminating these methods through a discourse rooted in human rights principles. This historical narrative highlights WHO's enduring commitment to addressing global health challenges related to population and reproductive health.

This report provides an overview of activities in 2020 that demonstrate the impact of research supported by TDR to improve the health and well-being of people burdened by infectious diseases of poverty. This body of research is leading to new solutions for implementation and improved access to existing health solutions. This is the result of TDR’s strategic priorities of research for implementation, strengthening research capacity and global engagement acting in an integrated manner.
