How safe are menstrual cups?
Help us understand how harmful microbes interact with menstrual cups and discs, and the potential impacts on our bodies.
Note that this page is for people making a donation from the US. To donate from New Zealand or anywhere else, please make a gift on our NZ donation page.
The Project
Menstrual cups and discs — reusable devices placed inside the vagina to collect period blood — are growing more popular thanks to being a cheaper and more environmentally sustainable way of managing periods.
But these products can be an infection risk. Despite being available for decades, there are just a handful of published studies that have investigated the microbiological safety of menstrual cups. Worryingly, these experiments didn’t accurately replicate the conditions inside a menstruating human body or how cups are typically used — and their findings contradict each other!
We want to investigate how well harmful microbes can stick to and grow on menstrual cups and discs under the conditions they encounter inside our bodies and in our day to day lives. Raising $150,000 will let us get into the lab and spend the next year testing a bunch of cups and discs made of different materials and across a wide price range.
