There is evidence that sexual and reproductive health (SRH) is strongly linked to menstrual health and hygiene (MHH). Yet globally, governments, policymakers, and non-government organisations (NGOs) fail to include MHH in their SRH agenda. This brief examines the most crucial evidence linking MHH and SRH, and offers a framework to underline the imperative of pushing MHH into the mainstream of India’s SRH agenda. It argues that gaps in targets for promoting menstrual health must be filled, if the global community is to achieve the Sustainable Development Goals on health and well-being, education, and gender equality.
