Between 2018 and 2020, the GEMS Project implemented a transformative intervention that broke the long-standing silence around menstruation among adolescent girls in six secondary schools across Southeast Nigeria. Through a combination of menstrual health education, safe-space dialogue sessions, and the distribution of menstrual hygiene kits, the project reached over 600 girls directly. Participants reported increased confidence, improved menstrual hygiene practices, and reduced school absenteeism during their menstrual periods. Beyond the girls themselves, the project also strengthened the capacity of school staff to provide ongoing menstrual health education and support. As a result, several participating schools established menstrual hygiene clubs—many of which remain active today. This achievement not only addressed a deeply rooted cultural taboo but also reinforced our approach of integrating education, empowerment, and community involvement. It affirmed our belief that when girls are informed, supported, and empowered, they can challenge harmful norms and thrive. The success of the GEMS Project continues to inspire our ongoing and future work in advancing girls’ rights, health, and dignity across rural communities in Nigeria.
