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.

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.

"Since the 1970s, health professionals, researchers, governments, advocacy groups, and commercial interests have invested in the pursuit of something called 'sexual health'. Programs were launched, organizations founded, initiatives funded, products sold-and yet, no book before this one asks: What does it mean to be sexually healthy? When did people conceive of a form of health called sexual health? And how did it become the gateway to addressing a host of social harms and the reimagining of private desires and public dreams? Offering an entryway into the distinctive worlds of sexual health, this book traverses the distance from the research and treatment domains where sexual health is assessed, measured, and improved to the "sex expos" that invite attendees to "leave their inhibitions at the door and explore today's top intimacy products" and beyond. Sexual health encompasses wildly disparate agendas and speaks to innumerable concerns-from sexual dysfunction to sexual violence, from HIV prevention to reproductive freedom, to the practicalities of sexual contact during a global pandemic. Rather than a thing apart, sexual health is intertwined with nearly every conceivable topical debate-and more of them every day. Through his wide-ranging exploration, Steven Epstein provides the critical tools needed to bring into focus the different faces of sexual health and parse the debates that swirl around it"--
