There is a case where test animals in laboratories have more stress when a male human is there, compared to female humans. https://www.nature.com/articles/nmet

  Interesting. Could it be pheromones? Or maybe the combination of men sweating more (I actually don't know if that's true, maybe it's just my bias, as I'm a male and men generally smell worse to me than women) and women having a better sense of smell. Or maybe men are more prone to stress (I don't necessarily mean negative stress, men also seem to prefer positive stress, i.e. adrenaline-filled activities), and animals/humans smell that...

    In my experience male chickens act more aggressively to male humans than female humans. I think they are aware of our sex.

      My brother's African Gray parrot was always friendly to him and an asshole to his wife. Maybe it was sex, but maybe it was just height. I'm given to understand that bird hierarchy is pretty concerned with elevation.

    Another possibility is that women are socialized to move more "gracefully" (i.e. less suddenly) than men; and their body language is thus less threatening to animals.

      Maybe there is more to it (possibly in the realm of emotions) than body language or pheromones.
