A rhesus macaque mom climbs into a hammock with her infant at the Wisconsin National Primate Research Center. Females reach puberty at around age three, while males are sexually mature by age four. Gestation is five and a half months, with one infant born at a time and often a year or more between births. Females can reproduce until they are about 20 years old. Rhesus monkeys can live in captivity well into their 30s.
