Several years ago I pulled a pair of shorts off the rack at Performance one day and arrived home to discover that they were women's (I'm a guy). I was too lazy to take them back, and I've worn them for several years in my regular rotation of shorts.
As a guy, I can attest to their being cut a bit different—not quite as tight through the hips. The chamois is a little different, but not so much as to be noticable. The thing I notice most is that there are no "grabbers" on the leg openings -- those little rubbery things that theoretically keep the shorts from climbing up the legs.
As I said, this was a couple of years ago. In the same brand (i.e., "Century") of shorts, Performance has since changed the shapes/styles of chamois, so my experience may not repeat itself.
