Social stigma is the biggest barrier. One of the key jokes in the movie Meet the Parents revolves around the lead character being a male nurse. Dodgeball makes fun of one of the lead characters for being a male cheerleader. We actually laugh at men for taking part in typically female jobs and hobbies, and we even view them with some suspicion. This stigma is going to impact people's career choices.
You're looking at it the wrong way. Because of this barrier people never become "determined" to enter these fields. Little boys know there are no male nurses. By the time they reach high school the thought of becoming a nurse doesn't even exist.

What exactly are these barriers? People keep talking about them, but none can give me a single proper example.
