There hasn't been much research looking at the effects on women, partly because this has been a fairly small research area. I have perhaps been the most frequent contributor in it. When I was interviewing with the University of Manitoba many years ago, the chair at the time, John Adair, took me aside and told me he'd be very happy to have me there and that I could do any research I'd like, but, as a man, he wanted to tell me that I was going to get into trouble and get him into trouble if I used female subjects. He asked me to do him a favour, though he wouldn't require it, and refrain from doing any studies focusing on women.
There have been a few studies, but relatively speaking, it's very few. I should say that I tried to get women graduate students to be the ones doing the research about that aspect. They generally refuse because being exposed to violent pornography bothered them too much.
