For centuries, menstruation has been shrouded in taboo, subjected to stigmatizing rituals, or has simply been ignored. Thanks to systematic efforts and awareness raising during the past three decades, menstrual health (MH) is now recognized as a public health and human rights concern, essential for women’s equitable participation in society. Safety concerns surrounding menstrual hygiene products have garnered global attention from consumer groups and women’s health activists. Significant initiatives now address menstrual health and related products, particularly in low-income countries. However, we are still facing a dearth of evidence on the health impacts of menstrual products.

This project seeks to increase the knowledge on this issue by establishing a comprehensive evidence base on the health effects of various menstrual products on the vaginal microbiome, a gatekeeper of women’s health.

To achieve its goals, the research team will examine women’s practices and preferences regarding menstrual hygiene products in Peru, and Cameroon, while conducting a systematic global review to provide context. Additionally, the project will address gaps in evidence by studying how menstrual products impact the vaginal microbiome through ongoing multi-country citizen-science cohorts of women participating in vaginal microbiome screening.

Collaborating with menstrual health leaders, such as counsellors, doctors and community representatives, the project will raise awareness among concerned stakeholders about the need for improved scientific research, evidence, and regulatory guidance on menstrual products to ensure the safety of women wherever these products are used.
