About This File

Welcome to PregnancyV3

It works for Female Players, the MCM setting allows it to also work for just the Player, Player & Female Companions or Female Companions and Female NPC's, though be careful not to over use this as it could become a lag fest if too many NPC's are running fertility scripts. You can use the MCM sliders to select who can be fertile male and female. MCM sliders also select if Creatures & Bots can cause pregnancy.

Pregnancy swaps the outfits worn to ones of various stages P1-P7,P1-P4 being normal human pregnancies, most outfits only have up to P3, some outfits like metal armor or power armor don't stretch and have to be crafted or brought. RemoveWorkshopNeeds.esp is a file that will cause all outfits to swap. Some outfits may even tear at larger sizes too. The outfit will usually be Vanilla/Type3Cali, there are a handful of T3M and BnB versions of outfit meshes that will be used if the player or NPC bodytype in SCR is set to BnB or T3M. There are nude pregnant bodysuit meashes for T3Cali, BnB & T3M only. Pregnancy supports DLC and TTW creatures if they are installed but does not require them.

Pregnancy has MCM options for Fertility adjustment, Male Pregnancy (Player only), any creature you can intitate sex with, Android race pregnancy (ARES), Menstruation (no visible effects), Pregnancy speed & Offspring Race Chances.

Pregnancy does not cause sex to occur, it just detects sex occurring from other Sexout mods.
If you are new to this, make sure everything else in Sexout works ok before adding this. Get something basic like SexoutSex or SexoutSexLite working first. Don't install 30 plugins at once without knowing what they do or how they work, hit go and then not know what is causing the problem and start reporting issues in the wrong mod threads, there are a heap of old dead plugins on Lovers Lab that are for old Sexout or just too many versions behind current SexoutNG & SCR to work :classic_smile:

Also note this is a complex mod, as there are scripts running on each offspring to grow them and adding fertility/pregnancy to random NPC's may cause lag & freezing depending on how many and how good your computer is, I can't do anything about that, it's just an computer/engine limitation, if you want to get a specific NPC pregnant turn on Female NPC pregnancy before sex then set it back again afterwards and that will allow the fertility tokens to be added then and continue to work. Also consider killing or selling Offspring if you have too many. This mod will grind your game to nearly a halt & cause stuttering and all sorts of issues if Pregnancy is used on everyone or you have a lot of OffSpring. The scripts check for pregnancy every 30minutes game time to reduce lag and update for time missed during fast travel/sleep/wait.

Sexout OffSpring
What I have done is split the management of offspring from SexoutPregnancy into it's own ESM. So Pregnancy only plops an egg or baby into the cold cruel world. From birth onwards Offspring manages the growth of the eggs/babies/pups/young/mature Offspring. The growth speeds and follower options are still adjusted in the Pregnancy MCM menu.

This means other modders have the option to do their own offspring handling for behaviour etc. Or this now gives the option to completely replace Offspring with their own mod. The Offspring eggs, creatures and children etc remain in SCR so this shouldn't effect any mods using them. SexoutOffspring only contains the control scripting and behaviour package stuff. So if you don't install this, or another OffSpring replacement, Offspring will still be born but will not grow or do anything except random sandbox behaviour. Eggs will not hatch. Larve will not grow.

I have made a few improvements to the follower control aspect, but don't have a lot of interest in doing much more with this other than bug fixes.

SexoutOffspring requires SCR and Pregnancy versions of the same date or later

SexoutOffspring needs to be below SCR & SexoutPregnancy in Load Order so Load Order is:

Never merge/bash Sexout mods, I can guarantee failures in all my mods if you try this.

The data file contains some of the Baby Assets you will need.

NVSE Latest beta
NX_Extender Latest version
SexoutNG Latest version
Sexout Common Resources (SCR) same date or later
SexoutSpunk Latest Version

Pregnancy requires SCR, SexoutSharedResources (SSR) conflicts with SCR, so you can't use it with Pregnancy.
Make sure you go to EvilRunner & User29's Maternity clothes threads and get the latest clothing files too.

You also need MCM to change any settings.

Full List & Download links are in the second post of the Support Topic

Please use the Support Topic Button on the right for more information, support & beta versions. The beta should only be used by experienced users and issues with it reported in it's support thread. The second post here contains more information and link for the beta version containing technical stuff where modders can request new features.

You will also need to download the Maternity clothing packs listed in the 2nd Post if you want to use those outfits in Plugins or SexoutStore.

Also remember when you update this it may change itself in your load order, use the following Load order or it will crash your game:

The file version is in YYYYMMDD.x format, eg 20120122.2 = 2012-01-22 Version2.
When reporting issues please state what version of SCR & Pregnancy you are using.

The Torrent isn't necessary, it's just an alternative download for the data pack, not the esm.

For users that use Wrye Flash to make a bashed patches. Wrye Flash completely undoes all changes that RemoveWorkstationNeeds does, so make sure that that plugin is not included in the bashed patch and loads AFTER bashed Patch, 0.esp.


Translations are cool, just don't claim my stuff is yours.
No uploading elsewhere than LoverLab.
No Kiddie Porn usage, I don't want to be involved in any crap that hits the fan. 
I DO NOT support any use of my mods for kiddie porn or adult sexual situations like child pregnancy.
If I disappear or am inactive on Lovers Lab for over 3 months, others are free to take over my mods, don't claim its yours unless you do a reasonable amount of upgrading, then just thank me in the credits :)


Basically I don't have FONV installed anymore and the time to continue work on this other than the occasional bugfix if enough information is given. If anyone wants to submit updates or overhaul it and use any of my code or assets for the enjoyment of the community go for it, just keep free and on LoversLab and give me some credit :classic_smile:


I have no problems with anyone translating this to FO3 or other Languages, just give me credit and link back to LoversLab
Russian Translation: http://gamesource.ru/index.php?s=&showtopic=2618&view=findpost&p=51428

Known Issues:

The players nude body is blocked from swapping to the pregnant version during sex, this is an engine limitation to do with the camera, if the players body tries to swap bodies during sex it will result in a invisible body, NPC's will swap ok. So strip off before starting sex if you want to see a baby bump.
