In the editorial for the May issue the PLoS Medicine editors discuss how clinical research could help to promote better sexual health for all. From the growing burden of sexually transmitted infections to the unmet contraceptive needs of specific groups, sexual health problems are complex, as they sit at the intersection of health, culture, religion, and politics. The editorial draws particular attention to unmet contraceptive needs and unsafe sex, which both figure in the top 20 risk factors for mortality and burden of disease and have been included in PLoS Medicine's recently announced priority areas for publication. Key PLoS Medicine papers that highlight some of the varied themes in sexual health are also highlighted. The editorial concludes that "It is time to realign research and policy making to promote better sexual health for all."
