Right now it's reading very much as a dude. If you're intent on having a more anatomically defined base mesh for sculpting i'd recommend making one for a dude and one for a chick because the difference between your stereotypical man and woman is pretty huge. I think by sticking to just 1 mesh for everything you're going to give yourself more work to do. It's going to take more work to make this base mesh sexually unidentifiable, and once you've managed that you've just given yourself more sculpting work to do to bring it back to looking like either a man or a woman.
For this kind of base mesh where i'm assuming you want to be able to re-use it for as many characters as possible while retaining the smallest imprint of the base (?), the solution that would save you the most time would be to just use tubes for all the limbs and let the sculpting do the hard anatomy work.
if you want it to be androgynous, try starting from a younger female body type. at a young age, the differences in shoulder width are less noticable, and flat chested women with short hair could be mistaken for a feminine guy. also using a simpler animation style would help, like this: http://reviewsoutsidethebox.files.wo..._dragon_48.jpg
