In one year, women tend to lose about 450ml of blood from their period. That’s just a bit more than a small cup of soda. That’s also a lot of blood when you think of all the ladies.
In developed countries, women typically have reliable access to feminine hygiene products to better handle monthly bleeding. For underdeveloped countries, this is not always the case. Lack of access to reliable feminine hygiene can greatly impact the status of living during monthly cycles, even education. Unesco estimates that 10 percent of African girls will quit school because of difficulties associated with menstruation.
On average, women use roughly 11,000 tampons in their lifetime. (Please note that these are not sperm. That’s patriarchy whispering to your subsconcious. These are tampons. Bloody, bloody tampons.)
According to a sanitary towel manufacturer, roughly 75% of women living in cities still buy their pads wrapped in a brown bag or newspaper due to shame and embarrassment of menstruation.
“Girls suffer if they aren’t empowered to manage their menstrual cycle without pain and shame each month. Their health, schooling and dignity are in the balance.”

-Chris Williams, the executive director of the Water Supply and Sanitation Collaborative Council, which runs the Menstrual Hygiene Management Lab.
