The geekfeminism link addresses the almost-strawman argument that women don't have the math or analytical skills needed for CS. It doesn't address the possibility that there are biological reasons for differing levels of interest in the field.
The second link discusses interests and influences for female undergrads majoring in some kind of engineering, not CS, though I still think it is somewhat relevant. I find the influence on family members to be the most interesting.
The third link has papers specifically related to interest. One is titled "The Anatomy of Interest." It discusses why women who started college enthusiastic about CS ended up leaving.
