Concept for omegaverse:
Being around enough pregnancy hormones or new babies suppresses rut cycles in alphas.
Evolutionarily, it's to prevent a possibly violent rut while there's a vulnerable individual around. Babies are fragile, and a pregnant omega more fragile than usual, but also! The omega can't get MORE pregnant, so it's a waste of resources.
While the omega can get pregnant again a few months after giving birth, ovulating every 3-4 months as usual, a true heat doesn't hit until the baby is a year or two old. (There's a wide window, and it's usually around weaning, but delay too long or star too early on that, and it'll happen anyway.)
Generally, just being around a pregnant omega a few hours a day won't do much, especially if you aren't mated, so just having a pregnant coworker won't impact you unless you're hooking up in your free time... but working as an ob/gyn or in a maternity ward DOES. That's a lot of pregnant people and babies to be around!
It's a favored profession for asexual alphas who don't want a rut to force them into Wanting The Thing They Don't Want.
It's not birth control, btw. It doesn't actually impact sperm count, just prevents the high libido and aggression period.
lmao Maybe if you huff pregnancy hormones (and don't have the kink) you have acne control like IRL people take bc.
