I think the problem with computer science in general is that it's one of the few careers you need to like at an early age and do a lot of self-directed study before you even enter college, or you are at a disadvantage compared to others. This affects both men and women, and keep in mind most men aren't interested in those fields either.
I do strongly suspect that has a lot to do with the fall-off in women working in CS. (It's probably not limited to that though it probably also leads to some self-perpetuating feedback loops.) It's almost unique among careers in that regard with the arts (playing music, etc.) or sports being the only other major exceptions.
You don't just decide in high school you'd like to do the violin thing and apply to Juilliard. But it's considered perfectly normal to decide you really liked high school chemistry, even if that's the extent of your exposure to it, and consider majoring in it once you hit college.
On the other hand, I've taken a couple of programming MOOCs based on intro programming courses at a couple of elite schools. The idea that I could have made it through them as a freshman never having touched a text editor/IDE is farcical. Yet [EDITED for clarity: when I took an intro programming course as a mechanical engineer in college way back when there was no expectation that I had ever touched a computer]. (I had done a little BASIC programming in high school but it was very rudimentary.)
