[Mod] Insemination & Surrogacy (RPO, Mod 8) - Sims 4

Mod 8 of the Relationship & Pregnancy Overhaul collection.

Check Global Update Notes post for Latest Update notes.

See Full & Detailed Description here

  • COMPATIBILITY WITH TURBODRIVER MODS: "override game / mod pregnancy" needs to be set to off in WW / WonW settings or the surrogate can't get pregnant.

  • If a surrogate doesn't have the option to send away a child because the birth happened while off lot, try the workaround below:

- DO NOT romance or Play NPC surrogates (you can obviously play your played sim surrogate, just not the NPC auto-generated ones). You will find that I blocked most romance options for them, too. Why? Because their pregnancy system is altered for them to be NPC surrogates and they are not to be played!! You might encounter them in the world without knowing that they are a surrogate, but romance being unavailable with them will be a dead tell :) If you want to play with an auto-generated NPC surrogate, you will have to first make them not be a NPC surrogate anymore, you can't have both. To do so, remove the trait 'Trait_IsNPCSurrogate' from them, through my mod under 'actions' or through any mod that removes traits.

Hello, Just downloaded this. is it up to date? i dont see any interaction related to surrogacy when I click on my selected sim

Lumpinou · December 5, 2025

Hi, Check your installation especially that you have the core files, a mod Hound scan might help

Hi, Ive used this mod before with no issue but now the tab to select pregnancy options does not show anymore. What can I do?

L
Lumpinou · October 16, 2025

Hi, could be an installation problem or a problem with the sim in particular. Unfortunately to say which it is, we'd need to see sim and file logs so we can't do that here since Patreon doesn't do files on comments, would have to be on the discord

Hi! I am trying to remove the npc surrogate trait from a sim. Im having some trouble finding it through the actions rpo special actions. I also tried to shift click and find it but it wasnt there. Is there another way to do it? Thank you!

Lumpinou · June 6, 2025

Hi, you can use Sim Info Manager for it

Hi, is there a way to cancel or cheat out of a surrogacy progress. I started a surrogacy for, my surrogate gave birth but i made a mistake and deleted the baby from my sim's relationship before she could give me the baby now i can't start another surrogacy or insemination because i still have a process still ongoing.

L
Lumpinou · March 24, 2025

Hi, yes, under family and Pregnancy then status, removing pregnancy markers clears surrogacy in progress too Sorry for the delay, Patreon doesn't always notify of comments

Brianna Lemke · November 25, 2024

Even if I have invited over the future parents and I have invited them to feel the baby, all of the surrogacy interactions say that I have not told them about the pregnancy so I can't as for preferred name or any of the other interactions.

L
Lumpinou · November 25, 2024

Hi, so I know what to look at, what other interactions are you trying to do and between who?

Thaaeroprincess87 · September 23, 2024

Is there a way to increase the cost of the Intrauterine and invitro fertilization procedures?

L
Lumpinou · September 23, 2024

Hi, no, but you can use cheats to take out more money if you want

R
Raymond Wilkinson · September 3, 2024

Is there anyway that we could possibly or you possibly could make it to where the surrogates get paid more?

L
Lumpinou · September 23, 2024

Hi, users can't change prices no, but you can use cheats to take out or give more money if you want

My female sim is trying artificial insemination due to low fertility; her Elder husband has agreed to it but isn't showing up in the list of possible donors. Is it because he's an Elder or is something else bugging out?

L
Lumpinou · August 6, 2024

Hi! Definitely would be the age thing, but that's something I can consider altering

Why the Debug of surrogacy doesn’t show up for me?

L
Lumpinou · July 31, 2024

Check your rpo settings, make sure you have the first one enabled

My bio mom died before the surrogate could deliver their baby. What can I do? The only option is to keep the baby or put it up for adoption once it’s an infant. Neither were a part of my storyline. Will my sim still be paid?

L
Lumpinou · February 3, 2024

Hi, If the sim died there's nobody to give the baby to. I'm not sure what other options could happen in that case other than keep or give for adoption. No the sim won't be paid. I advise to either cheat get rid of the baby, clear pregnancy markers and try again or just roll with it. I will consider preventing the Sims who receive babies from surrogacy from dying.

Hey Lumpinou! I am having an issue with IVF option. I had two female sims that were in a relationship, one decided to do IVF and used a donor which I picked. In the family tree it's showing up as the donor and the female sim as the parents, instead of the two moms and relationship bit in their info panel of having a baby together through IVF. Do you know how to fix that? I also tried to go through the actions panel and try to add a relationship bit for having a child together for the two moms, but there is only an option of fathering...Hopefully you might know a work around for this! Thank you so much for this amazing mod. You are amazing and make this game fun!

L
Lumpinou · January 23, 2024

Family tree is DNA so it will show the donor of the sperm and the egg, ie the carrier and the donor you chose. Sim profile shows relationships and should say 'mother' for both of them and nothing for the donor If not, sth is going wrong and we need sim logs to get any idea of what Sorry for late reply, patreon often does not notify properly

Shemira Henry · July 27, 2023

I sent surrogate baby to the family and received payment, but I cannot get the baby off my lot. It's still there! I even shift-deleted the baby with testing cheats on but it still isn't working

Lumpinou · July 27, 2023

If you have problems with babies, age them up and send them via rpo general management

Hi! quick question - I have two lesbian sims who want to have a baby. Since it's my legacy sim, I want to have the genes pass on - so my thought was to ask my heir's wife's brother to be the sperm donor. The RPO menu doesn't show up when talking to him (for either) - is this because he is in the family tree (BIL) or is there something else preventing this? Both my sims have discussed having a donor and agreed to it. Should I just use the science baby instead (I'd like to have the realism of RPO). Thanks!!

L
Lumpinou · May 10, 2023

The surrogacy starts from the sim who will be pregnant, so, you would do it from her and not via talking to him - he should pop up in the menu to choose the sim who gives the samples

Small no pressure idea: could men periodically donate sperm for a small amount of simoleans? (Extra cool if it lowered their fertility or caused them to reject woohoo for an hour or too, but probably not worth the effort for such a small effect.) And maybe women could do egg donation for much higher payout only if YA and healthy (maybe even requiring certain traits, and this one hopefully impacting fertility temporarily). You've probably considered this before, and if you have reasons for not doing it, no need to explain or even reply. 💕

Is it possible through this module to get a genetically child in a pair of two men through a surrogate mother or not?

L
Lumpinou · March 1, 2023

Hi, the mod sticks to realism and therefore, if two Sims who cannot be impregnated but can impregnate use a surrogate, one of them would be considered sperm donor and the surrogate would be considered egg donor. If you change your sim's impregnation abilities then that can be different. Gender itself is completely irrelevant and never looked at, but where the eggs and where the sperms are is what matters basically. Hope this helps!

tiltowhirl · January 24, 2023

For two sims with low fertility, is it possible to have a baby via IVF? When I tried, I only saw random and chosen donor.

L
Lumpinou · January 24, 2023

Yeah, you can choose the other sim as donor

Does Panda’s mod conflict with the surrogacy? Like if my sims is the carrier can I send my sim to the hospital to deliver via natural birth or do I still have to deliver at home?

L
Lumpinou · December 22, 2022

Surrogates have to deliver at home
