Essays / Help with an introduction for an essay on the stereotype that men shouldn't be nurses [5]

So here is my rough draft for my introduction: "When the first nursing school was started, only men were considered "pure" enough to become nurses. Now it is almost opposite! Instead of being an all-male nurse population it is now predominantly female. Why is this so? Men are capable of doing all the same things that women can do and more. Well as I did my research I discovered why females dominate the nursing population."
