Gen 2 - How to define Hidden Power AND gender

[Macaulyn]

So, when I pick my Hidden Power for my Pokemon in a Gen 2 game, PKHeX seems to be smart enough to adapt the ?Vs (I know it's not EVs nor IVs) to be the highest possible, but it usually changes the Pokemon's gender, which I don't want (when I change the Pokemon's gender back to where it was, the Hidden Power ends up changed to another too). How do I set a specific HP and gender?

Gender is derived from the Attack DV and the Gender ratio in Gen 2. Hidden Power is derived from DVs. See details here:

You'll have to play around with the DV values to get the desired Hidden Power and Gender.

Really? Whenever I try to change, I lose like 20 power in the HP. Is there any calculator?
