Can't Get Abducted

The bonuses to the base abduction chance (which is 1%) comes from collecting space rocks, not keeping them on the lot or in the sim's inventory, and using the telescope. Using the telescope can be done anytime of the day, but it might be best to do it before the abduction time frame (midnight to 3 AM). These bonuses are temporary and only last through the next abduction period. If you don't get an abduction you need to repeat both (if you want the maximum chance) each day you want to try again.

Specifically, each space rock collected adds 15% to the base chance for an abduction up to 60% from space rocks. Using the telescope adds 14%. So the maximum chance you can get without mods is 75% that night. If there is no abduction the household must collect another 4 space rocks and use the telescope again on another day (again, to maximize the chances), probably before midnight but I'm not positive about that. I always collect the space rocks and use the telescope before midnight when I'm trying to get a sim abducted.

I have used the buydebug cheat to add space rock spawners on community lots so my sims would have plenty of space rocks to collect. That's something to consider if you are desperate. It doesn't matter who in the household collects the rocks or uses the telescope. Sometimes I have children do both (they, of course, do not get abducted).

Finally, the abduction chance is per household, not any individual sim. So, when an abduction happens, it will be random who is picked (assuming they are eligible for an abduction, i.e. not children, toddlers, etc.). For the other sims in the household, send them off the lot during the abduction time frame (midnight to 3 AM) leaving only the sim you want abducted on the home lot. But keep them off owned venues (the game can try to abduct sims from owned venues, but the abduction will fail and nothing will happen). I usually send the rest of the teens, YAs, adults, elders, plumbots, etc., in the household to the spa, or have them tour/visit various rabbit holes during that time. Mostly because in the one game where I had a male sim get abducted 19+ times (and had 19 alien kids, I was shooting for 26), that household owned most of the venues in town. Oh, abductions can occur on owned additional homes too, so don't send the rest of the household to one of those lots if they have any.

Leaving 5 or more space rocks on the lot adds to the chances of getting an alien visitation (where they show up and wander around the lot and scan things). Space rocks on the lot do not add to the abduction chances. As far as I know, space rocks in a sim's inventory don't do anything.

Lastly, the chance of a male sim getting impregnated is 33%. The sim must be human and male, occults cannot get alien pregnant. At least not without mods.

Speaking of mods, there are various mods out there that will increase the base abduction chance to 100%, increase the male pregnancy chance to 100%, and allow female sims to get alien pregnant. In the game I mentioned above I used NRaas Retuner to set the male pregnancy chance to 100% because I wanted to raise 26 aliens in that game (one for each letter of the alphabet). I haven't finished that game but I think I'm around Q or maybe T. Lol, it's been a while.

There are no cheats for alien abductions/pregnancy that I know of.

Good luck.

Thanks so much for the help! I've had the rocks on my lot. That must be something I did wrong.

Sorry, I didn't mean to imply that rocks on the lot is bad or wrong, it's just not helping abductions. I did the same thing when I first started playing. I think the lore in the community about how to get abductions is a bit confused.

Now, I just use space rocks on lot most frequently for landscaping, especially the gigantic ones.

Hey so this literally works every single time on my game when I want an abduction.
1. Do the buydebug cheat and put some average plants on your lot like apple tree, watermelon, and etc. oh and don't worry if their wilted (i usually put them in the front yard and bunched up together)
2. In the morning have your sim use the telescope for at least 2hrs
3. Have your sim collect two space rocks (size does not matter as long as they are space rocks)
4. Have you sim go home and analyze the space rocks and keep them in your inventory
5. When it hits 11pm go ahead and start stargazing

Now the aliens may not come until like 2:30 am but they still come now once your male sim has been abducted make sure you save your game about 20mins before that alien abduction moodlet disappears because if it disappear and doesn't show the unexpected weight gain you can just go back to main menu without saving and usually the second time is the charm. I can literally do this back to back and get an alien abduction oh and you do not need to put out new plants after each abduction.

*Warning* If you have a witch in your household or maybe friend that can perform sunlight charm stay away from them because one day my witch had did it on her own and then my male sims "unexpected weight gain" moodlet was gone. Hope you have fun and let me know if these steps work really good for you. :)

Have you considered using a mod? I found the perfect one, and a sim of mine got abducted at least every other night, sometimes for days in a row.

You can use this mod this mod from bluegenjutsu from sims asylum (you'll need a free registration to view the link). This mod allows for much more abductions! If you want one every night, I'd go for extreme, but if you just want more, I'd go for more. You can see all the bonuses she has so you can act accordingly with your active sims.

I have the same problem. The alien just visited my house quick and fast then he leave.

Make sure you have rocks on garden and 'search galaxy' in the afternoon. Go outside at 11pm and wait until 12 midnight. Works for me my sim got abducted everyday for a week :)

Try having space rocks in your sim's inventory. My sim had 5 space rocks and he used telescope to search galaxy. At midnight, he was abducted by aliens. And this was first male pregnancy in my game, too.

At first I thought that was untrue, but then I thought back over my games, and they get abducted most often when I collect rocks, not from having them.
