I think it's more like that in comics, do an evil mastermind's minions really have an even male/female ratio? A team of soldiers are pretty much always guys, female ninjas are usually the rarer, most skilled femme fatale type, street gangs are an all boys' club (this is evident in the enemy groups as well). While for zombies it's not really relevant, and completely so with robots.
You don't have to go into discrimination to explain why we don't have female minions. There's plenty of thematic and practical reasons.
