Gooochyee, I don't understand the question... If you mean, do I make new saves every time a Sim gets abducted? No, when my Sim is being abducted I save the game, I wait a couple of SIM days and if nothing happens I just go to the main menu without saving and then reload the game with the same Sim being abducted and try again.
As you can imagine I sometimes get bored playing the same Sim over and over again, then I load another household and try getting another male Sim abducted.
I now use the stats.set_stat commodity_alienabduction_cooldown 0 and interactions.push AlienAbductions_BeAbducted cheats. That's quicker than waiting until "it" happens.
Meanwhile I've had males abducted 4 or 5 times in a row in a same session (meaning I don't leave the game): not pregnant. I managed to get all types of males abducted hundreds of times, one of them should be pregnant by now. I have tested "regular Sims" and "spell casters".
I also checked old games (from before the patch) in which I have male Sims who have been abducted and pregnant several times, but they also fail to attract the alien pollinator's attention...
Either I'm the unluckiest person in the world, either there's something wrong with the (my?) game.
