Currently, there are about 3.73 billion women in the world. According to the World Health Organization (WHO), 52%, or 1.9 billion, of those women are of reproductive age, thus menstruating (WHO, 2018). Women at some point in their life will go through the reproductive age and thus, will experience menstruation. It has been estimated that daily 300 million women are menstruating; on average a woman will spend about 3,500 days during her life menstruating. Many adolescent girls and women of menstruating age live in poor socio-economic environments. 663 million people lack basic access to safe water, and 2.4 billion people lack adequate access to basic sanitary conditions. For women and girls, the lack of safe, accessible water, sanitation and hygiene (WASH) is particularly troubling during menstruation and childbirth. It has been estimated that half a billion (or 13%) of women lacked a place to defecate, have little to no privacy for menstrual hygiene management, and 3/4 of those lacked access to soap and water. In a 2014 study conducted in India, the researchers found that as many as 42% of women who participated in the study did not know about sanitary pads or from where in their anatomy menstruation originated, and that "most of them were scared or worried on first menstruation." More recently, studies have shown that 50% of women in India have experienced a UTI related to the inability to safely manage their period. When left untreated, UTIs can lead to kidney failure. Worldwide, in 2018, one in three women did not have access to a working toilet at all. Menstrual hygiene management issues have been ignored by professionals in the WASH sector, as well as in the health and education sectors. Health and psycho-social aspects Poor MHM may affect the reproductive tract, but the specific infections, the strength of effect, and the route of transmission remain unclear. In India, a majority of girls are at risk for reproductive tract infections (RTI) because of poor MHM. RTI can lead to various disabilities if not treated early on and are the cause of 30–50% of prenatal infection. Due to prejudices surrounding the issue, some women in India do not eat or take showers during their menstruation. Girls' self-image may be negatively impacted by adverse attitudes towards menstruation. Sanitation facilities at schools The onset of menstruation is challenging for school-aged girls in low-income settings. Impacts can include school absenteeism, missed
