[Series] Partial progress in sexual and reproductive health and rights: the influence of sociocultural, behavioural, structural, and technological changes on epidemiological trends

The concept of sexual and reproductive health and rights has evolved in the 21st century from previous narrower conceptualisations. In 2018, the Guttmacher–Lancet Commission proposed a broader and integrated defining framework, together with a package of essential health service elements. Despite this, progress on the sexual and reproductive health agenda has been inconsistent, with progress in some areas and considerable gaps in others. Even in areas that have seen breakthroughs in biomedicine and technology, progress has been partial owing to inadequacies in funding, policy, and implementation.
