McMaster Researchers Innovate Menstrual Cups with Absorbent Tablets

Research at McMaster University is addressing the challenges associated with menstrual products through the development of innovative absorbent tablets designed to enhance the use of menstrual cups. Led by professor Zeinab Hosseinidoust from the department of chemical engineering, the initiative aims to reduce the mess often linked with menstrual cups, ultimately promoting their wider adoption.

Despite the fact that nearly a quarter of the global population menstruates, advancements in menstrual products have been limited. Hosseinidoust emphasized the significant need for innovation in this area, stating, “This is a field ripe for innovation. There is so much that can be done.” Alongside associate professor Tohid Didar, Hosseinidoust’s team has created tablets that work in conjunction with menstrual cups, potentially making them more user-friendly.

Addressing Period Stigma and Practical Challenges

A growing body of research underscores the need for effective menstrual products. According to UN Women, over two billion people globally menstruate, yet many face challenges such as period poverty. In Canada, government studies reveal that one in six menstruators have experienced period poverty, with the average individual spending approximately $6,000 over their lifetime on menstrual products. Additionally, a troubling statistic shows that one in four Canadians view menstruation as “dirty and unclean.”

The introduction of absorbent tablets could address these issues. McMaster PhD candidate Shaghayegh Moghimi explained how the tablets, made from biodegradable seaweed-based materials, can facilitate the use of menstrual cups, particularly in public restrooms. “It would honestly just make everything more convenient,” said Dior David, a McMaster student, highlighting the practicality of such a solution.

These tablets offer a unique approach to menstrual health. Although they are single-use, which could initially seem to conflict with the eco-friendly nature of menstrual cups, they are flushable, cost-effective, and made from renewable resources. Hosseinidoust noted that by encouraging more individuals to try menstrual cups, the tablets could help decrease the reliance on disposable menstrual products globally.

Potential for Health Monitoring

In addition to improving usability, the tablets are being developed with health monitoring capabilities. Hosseinidoust’s research includes the integration of bacteriophages, which are viruses that target harmful bacteria without harming beneficial ones. This technology could enable the tablets to identify infections such as urinary tract infections and bacterial vaginosis, thus expanding their functionality beyond basic menstrual support.

As the research progresses, Hosseinidoust expressed enthusiasm about uncovering such a significant gap in menstrual product innovation. “But at the same time, as a woman, as a menstruating person, you think, ‘really?’” she remarked, reflecting on the long-standing stigma surrounding menstruation that often hinders progress in this field.

This initiative not only showcases the potential for innovative solutions in menstrual health but also emphasizes the importance of open dialogue about menstruation. As noted by fellow McMaster student Jennifer Abraham, increasing awareness and education surrounding menstrual products can empower individuals to make informed choices that suit their needs.

Through these developments, McMaster University is paving the way for a more inclusive and supportive environment for menstruators, ultimately contributing to reduced stigma and enhanced health outcomes.
