Summary
This study tests whether giving menstrual cups to economically vulnerable women in Kenya can lower rates of bacterial vaginosis (BV) and sexually transmitted infections (STIs). The cup is a reusable silicone device that collects menstrual blood and can be worn during sex. Researchers will track 408 women for up to three years to see if using the cup leads to a 25% drop in BV and fewer STIs like chlamydia and gonorrhea.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Menstrual cup (reusable silicone device)
What this could lead to
If it works, this could offer a low-cost, reusable tool to reduce bacterial vaginosis and sexually transmitted infections in vulnerable women.
What could go wrong
This is a single-arm trial with no comparison group, so results may be less reliable. The study is still early (Phase 2) and focused on a specific population in Kenya, so findings may not apply elsewhere.
