You can imagine that a man might be having a heart attack and he might be having nausea and jaw pain, but he's been told that those are women's symptoms of heart attack.

And so that's very dangerous for him because that will delay his treatment.

That does not mean that all women are going to respond the same way to a drug and all men are going to respond another way to the drug.

And yet that's kind of how a statistically significant difference is interpreted.
