Menstruation is a routine part of life for many girls, women, and others who menstruate. However, challenges such as limited access to menstrual products, inadequate facilities, lack of information, or financial barriers can make managing menstruation difficult and may affect health, education, work, and participation in daily activities. To address these challenges, a wide range of programs, policies, products, and interventions have been developed to support menstrual health. 

Understanding which approaches are most effective is essential for informing policies and programs and ensuring that resources are directed toward interventions with the greatest impact. The term “intervention” is often used broadly to describe any activity intended to improve menstrual health, but not all interventions have been rigorously evaluated. Scientific evidence helps distinguish approaches that are assumed to be helpful from those shown to improve health, education, wellbeing, or other outcomes. Despite growing attention to menstrual health interventions, evidence on which approaches are most effective, safe, and contextually appropriate remains limited and fragmented.
