From RJ's recent Q&A:

Is pregnant content planned?
It depends on what you mean by pregnant content. If you mean having sex with big-bellied pregnant women, then no there is no pregnant content planned. If you mean will it be possible to get the women pregnant, or will we ever see any of the women pregnant, then yes there are some plans for that.
Keep in mind that even though you can spend as many number of days as you’d like playing the game, the story is intended to take place during a single semester of college. That’s like 5 months or so. So even if you got a woman pregnant on the very first day you came back from Brazil in the game, she’s only going to be about 5 months pregnant at the end of the game. So it doesn’t make sense to have big-bellied pregnant women during the story.
