I think it could be extended to most or all electronic genres. Not counting DJ's, just producers. I think maybe a big factor is that creating music by MIDI sequencing is more technical and methodical than women are typically drawn to. Not to say they can't, but on average women are more drawn to interests with less rigid frameworks. In music you see a lot higher percentage of women who sing or play piano, violin, or some sort of immediately expressive instrument like that.
