Like that other guy said.
You can also kind of tell just by the way they draw, or at least what they include in their drawings. Most of the women artists pretty much focus on making the girls look pretty in that shoujo kind of way, with very little focus on giving the characters curves or something like that.
Hirasaka draws fairies wearing swimsuits and skintight american flags also he drew a loli h-doujin under a different name for FGO, Mizutaki draws whaletits and Akimaki Yuu overdoses on shounen action.
Obviously not a super clear cut comparison but it generally holds true, the girls draw less action and more pretty girls and the guys either draw action or lean more toward sexy girls.
