在巴西松鼠猴（Saimiri sciureus）群体中，40%的首次怀孕发生在3.5-4岁的雌性中；57%的首次怀孕发生在3.5岁至5岁之间，62%发生在2.5岁至4岁之间。总共79%的首次怀孕发生在2.5岁至5岁的女性中。70%的第一次怀孕和67%的第二次怀孕是不成功的。第一次怀孕不成功的女性最有可能第二次怀孕不成功，反之亦然。第一次怀孕后最常见的生殖事件是流产（33%）。
In a colony of squirrel monkeys (Saimiri sciureus) of Brazilian origin, 40% of all first pregnancies occurred among females aged 3.5–4 years; 57% of all first pregnancies occurred between the ages of 3.5 and 5 years while 62% occurred between the ages of 2.5 and 4 years. A total of 79% of all first pregnancies occurred among females between the ages of 2.5 and 5 years. 70% of all first pregnancies and 67% of all second pregnancies were unsuccessful. Females with unsuccessful first pregnancies were those most likely to have an unsuccessful second pregnancy, and vice versa. The most common reproductive event in the season immediately following first pregnancy was a failure to become pregnant (33%).
