Approximately one-quarter of the global population are women of reproductive age, most of whom menstruate every month.
A core function of a woman's reproductive system, menstruation is a healthy and normal occurrence in the female body. However, it can—and often does—become a challenge when individuals lack access to the resources, infrastructure, and social support they need to appropriately manage it.
This report captures key changes in the menstrual health and hygiene (MHH) space that have happened since the publication of An Opportunity to Address Menstrual Health and Gender Equity in 2016. We pay particular attention to the remaining gaps and highlight opportunities for further action and investment.
