Somewhat. Some designs look better with male genders and some look better with female genders in my head. I'm weird like that XD
Interesting thing I read in Bulbapedia a few years ago: Back in Gen 2 it was impossible to have a female shiny with perfect stats because female Pokemon by default had ever so slightly lower stats in some areas -this was fixed in Gen 3. So in G/S/C it was beneficial to have an all male team
