What is the main CLASS of male sex hormones. And the Class for female hormones.?

This is two different answers I think. I thought it was testosterone and Estradiol. But those aren't 'classes" so is this still right are they in fact "classes"?
Update: well I took the test and it says what "CLASS" so i went with the a one and I don't know if I got it correct clearly one means class and since testosterone was IN there I put the a one as the answer who know but thanks a lot!
