This kind of difference is always quite profound IMO. "Things for men" and "things for women" in almost every context is going to give different results. Doesn't matter if it's ppe or personal defense, or safety.... In almost all cases, there's going to be different results if you include gendered terms in your search.

I imagine "support" would yield a very different result when including your gender too. But like I said, far from the only examples.
