Abstract
Women in poor nations often have poor menstrual hygiene. We are testing whether an intervention within rural self-help groups can address these challenges. Specifically, we study
1. Can free trials increase the uptake of menstrual cups?
2. Do free trials by peers (which we hypothesize will increase uptake) increase cup uptake by peers who did not receive a free trial?
