Crusader Kings Console Commands

Hey so I haven't found an answer to this specific question anywhere and cannot make sense of the console commands for it. I'm trying to do a pagan dynasty with all badass women rulers. I'm trying to use the seduction focus for the opinion boosts, but would rather not end up with a million children. I'm wondering if anyone knows the console commands to adjust fertility. I'd like to choose when my rulers reproduce. I've tried everything I can think of (using every combination I can come up with of addmodifier, fertilitypenalty, etc.), and I keep coming up empty.

Cheats are activated by typing the relevant command. Into the console, then pressing Enter. The console is opened by pressing §+ Shift. Alt+ 2 1, Alt+ 0167 or may also work ( seems to be the majority console button, located beneath esc ). The cheat console is a transparent overlay above the character's tab.

C2 drug list printable. It seems like something that should be doable, and I'm pretty dumb so I figured I would check here if anyone knows whether or not it's possible. I know you can just use console commands to ace any kids you have, but having a string of dead children on the family page is pretty morbid.
