Alien pregnancy

Two male sims cannot get pregnant by woohooing. You'd need a same-sex pregnancy mod to enable Try For Baby, and male maternity wear (from MTS). But this is not "alien pregnancy" (the child will be half-alien though).

Male sims get alien pregnant as a result of being abducted. Once a sim is abducted they get the "Abducted" moodlet for 10 hrs. Once that expires there is a 33% chance of the abducted sim getting alien pregnant IF the sim is male and IF the sim is not an occult (or alien). Alien pregnant male sims get a 2-day "Unexpected Weight Gain" moodlet (which is the alien pregnancy moodlet) right after the "Abducted" moodlet wears off.

The chances for an abduction of a sim from the active household is 1%. To increase that for a single night you can have the household use the telescope and/or collect space rocks. Each space rock collected adds 15% to the abduction odds (capped at 60% bonus odds from space rocks) and use of the telescope adds 14% to the abduction odds. So, 75% total if the household uses the telescope and collects 4 space rocks. That's just for that night (midnight to 3 am). In my experience sims must be awake to be abducted. Furthermore, it's random which awake sim in the active household is abducted (aliens and sims child aged and younger cannot get abducted).

There are mods to increase (and decrease) these chances, and NRaas Retuner can be used to set the chances to whatever you wish.

Not sure about the university test. Usually I can send sims who just have the "Abducted" moodlet to uni since the game doesn't decide on alien pregnancy until that moodlet expires. In fact, you can save the game just before the "Abducted" moodlet ends and reload until you get the "Unexpected Weight Gain" moodlet. Or you can use Nraas MasterController to just give your male sim the "Unexpected Weight Gain" moodlet - that will work too. I think that once a male sim has the "Unexpected Weight Gain" moodlet they cannot enroll in university, but I never check that since the moodlet is pretty obvious. Even if you have NRaas Traveler set to allow pregnant sims to travel, I think alien pregnant male sims will lose the moodlet (and hence the alien baby) if they travel.

edit: once you invite an alien sim over (or move one in, or one visits) the only options available are the default TFB ones between male and female sims. Same-sex TFB requires a mod.

Lastly, alien pregnant male sims don't use maternity wear, they just get fat over the course of the alien pregnancy.

Just to add a small bit of info to the above excellent analysis if I may, on an alien male pregnancy the one who was abducted is not really the genetic parent of the child. They are acting as a surrogate to (presumably two I guess?) other alien parents not in the homeworld. Pregnancies that form by way of woohooing, no matter what the genders or alien status, are subject to the usual rules. :)

Okay thank you so much both of you that really cleared up all my questions that should really help my game

If I ran a recent test correctly, in an unmodded game I think the alien child from an abduction will only have one parent on the family tree, the male sim who had the alien pregnancy. I think it's NRaas SP (possibly along with the Population) module which adds an alien parent to the child's family tree. The added parent appears to be a random member of the alien household - not necessarily the alien who actually abducted the sim.

I also once took each member of the alien household into Edit in CAS and gave them each a different skintone color on the rainbow slider, along with different ear shapes and sizes. The alien babies were all the normal green with the usual alien ears. It seems that the game creates a new alien sim from scratch for abduction children. I've also adjusted custom body sliders for each alien sim in the alien household, but I don't remember if those were passed to abduction children in that game.

As you said though, alien children from TFB are subject to the usual rules.

Interesting. Well then, I would revise my prior comment to say that the abducted human male parent is acting as a surrogate to "something or other," but that just doesn't seem to sound as nice. ;)

@TreyNutz Whenever I got my sims abducted by aliens before I got mods, the alien baby always had an alien mother on their family tree. So it's not a mod giving them the alien parent.

That's really interesting to hear. I've usually have an alien parent on the family tree for alien abduction kids, but I can't remember my earliest experiences before I started using mods. Earlier this year though that stopped happening and alien abduction kids had only the abductee as a parent. I was also getting script errors from NRaas StoryProgression when alien kids were born (which has been resolved). I thought I tested out an alien abduction in a new TS3 folder with just Retuner and still got an abduction kid without an alien parent. Perhaps I did that test wrong or am remembering wrong.

Good tips about finding space rocks! Another approach is to put space rock spawners around town. In some games I'll put them on community lots so I know where they are.

@ laydayway If you have the Ambitions expansion pack and an alien already in your household, get the alien to summon a meteor. That's the quickest way to get space rocks.

I thought you were going to say "That's the quickest way to get rid of unwanted sims". :D

I had my first pregnant male by abduction recently and the child indeed has two parents.

Is there a NRaas way to save this mother to the bin? She is in the demography list but I don't know how to 'get' to her and capture her.

Note the same of the sim, then:

City Hall or Computer>NRaas>MasterController>Sim>Stylist>Alien DNA Percentage>Choose the line with 100%>Select the alien sim from the list. This will bring the sim in Stylist where you can save the sim to the Sim Bin.

If you meant to save her to the household bin, you can use MC's Add Sim command (I'd filter by Alien DNA Percentage) to add her to an empty lot, then save to the household bin from Edit Town.

Recreating alien in CAS is a bit problematic. They'll lose their alien DNA setting which means they'll get normal eyes and lose alien powers when you place them in the world to play. Their skin, hair, and face genetics should be fine. Once placed on a lot you can use MC to set their alien DNA percentage to 100% (which I think is supposed to be in decimal form, so 1.0, no matter what MC tells you). You can also set DNA percentage with DebugEnabler.

Thanks! Yes, I mean household bin so I'm going to try the second suggestion then. It's a bit complicated, but the abduction took place in a different save than the one I'm playing. Father and kid are already in my active save, but this topic made me realize there actually is a mother! So I want to put her in my active save as well (and use MC to make them all related again).
