The aim of this study was to determine whether or not sexual maturation is attained in the family group in captive-born Goeldi's monkey (Callimico goeldii) and if so, at what age and body weight. To monitor ovarian activity in 14 female Goeldi's monkeys, urinary content of pregnanediol-3alpha-glucuronide (PdG) was determined using radioimmunoassay. Urinary samples were collected between the ages of 6 and 70 weeks. Subjects became sexually mature while still housed in their family groups, at a median age of 57 weeks (48-< 70 weeks). Median body weight at the age of sexual maturity was 473 g (N=10; 420-543 g). This corresponded to 90% of the median non-pregnant body weight of breeding females in our colony (526 g, N=8). Therefore, Goeldi's monkey is similar to Leontopithecus but different from Cebuella, Callithrix, and Saguinus, in terms of daughters ovulating in the family group and at a relatively young age.
本研究的目的是确定圈养出生的戈氏狨猴（Callimico goeldii）在家庭群体中是否达到性成熟，如果达到，是在什么年龄和体重时达到。为监测14只雌性戈氏狨猴的卵巢活动，采用放射免疫分析法测定尿中孕二醇-3α-葡萄糖醛酸苷（PdG）的含量。在6至70周龄期间收集尿液样本。研究对象在仍生活在其家庭群体中时达到性成熟，中位年龄为57周（48 - <70周）。性成熟时的中位体重为473克（N = 10；420 - 543克）。这相当于我们饲养群体中繁殖雌性非怀孕体重中位数的90%（526克，N = 8）。因此，就雌性在家庭群体中且在相对年轻时排卵而言，戈氏狨猴与狮面狨相似，但与倭狨、普通狨和伶猴不同。
