@Amapola76 a while back in the Sims 4 Ideas section I had proposed that they provide a way for Sims who don't want physically intimate partners to get pregnant. It wasn't like science babies. Basically, I was suggesting that they add IUI as a fertility option. At the time I thought this was inclusive enough because even someone who has masculine gender settings across the board can be changed in CAS to allow pregnancy. I can see how it might be interpreted as excluding men though. At the end of the day, I'm glad my asexual sims have something.
