Thank you, feminists: in recent years, menstruation has finally become a topic of history, culture, and science, whose contours are endlessly explored. Once so taboo (let's remember the blue blood of 1980s sanitary towel ads), periods are now the subject of valuable voices, including from high-level athletes.

Inevitably, this deployment is accompanied by the marketing of new objects. There was the menstrual cup , then menstrual panties , which became popular during the #MeToo years, a real alternative to sanitary towels.
