Though I would not personally use the word slavery, I think there's something to be said about viewing women's bodies as property to the point where they are mutilated in a way that makes it more difficult to do even the most basic of tasks. Women were bought and sold chiefly by and for the benefit of men and things were done to them, often against their will, to make their market rate higher. Again, not sure I'd use the word slavery, but mostly because in the US it is so closely associated with chattel slavery that it is hard to warrant a comparison, even though it is pretty close to other forms of slavery.
