But for the most part, public facilities in Western nations were male-only until the Victorian era, which meant women had to improvise. If they had to be out and about longer than they could hold their bladders, women in the Victorian era would urinate over a gutter (long Victorian skirts allowed for some privacy). Some would even carry a small personal device called a urinette that they could use discretely under their skirts and then pour out, Cavanagh said. Strangely, these urinettes were sometimes shaped like the male genitals. [How Much Urine Can a Healthy Bladder Hold?]
This lack of female facilities reflected a notable attitude about women: that they should stay home. This "urinary leash" remains a problem in some developing nations, said Harvey Molotch, a sociologist at New York University and co-editor of "Toilet: The Public Restroom and the Politics of Sharing" (New York University Press, 2010). Women in India today, for example, often have to avoid eating or drinking too much if they have to be out in public, because there is no place for them to go, Molotch told Live Science.
