However, in The Sims 2 and in The Sims 4: Get to Work, male Sims can be impregnated as well, either through alien abduction or by the use of cheats. Under normal circumstances, only female Sims can become pregnant. If the player said 'yes', or was not given that option, a baby would immediately appear, forgoing any pregnancy period.
Prior to The Sims 2, kissing or playing in bed were the only interactions that could result in two Sims having a child - and the player could usually say yes or no to that. Pregnancy was introduced as a game feature in The Sims 2, and has appeared in each subsequent game. Pregnancy brings many physical and lifestyle changes to the pregnant Sim, including increasing body size, faster-decreasing motives, and forced maternity leave from work.
Pregnancy primarily affects adult and young adult female Sims. Pregnancy is a game mechanic and multiple-day event that begins after a successful ' Try for Baby' interaction between two Sims of the opposite sex, and ends with the pregnant female Sim giving birth to one or more newborn babies.
