The reproductive condition of three pairs of Bornean tarsiers (Tarsius bancanus) was documented for 16 months. Each pair was housed separately under a constant photoperiod (L:D = 11.5:12.5) similar to that in their native habitat. Reproductive cycles of females were monitored visually for 6 months and were then monitored with vaginal smears and measurements of external genitalia for an additional 10 months. Progressive proliferation and cornification of vaginal epithelial cells during proestrus and estrus was accompanied by an enlargement of the external genitalia. Cycle lengths averaged 24.0 ± 3.2 days. The external genitalia were swollen each cycle for a period of 6-9 days. Copulations occurred on the 1st day of estrus, which lasted 1-3 days. No menstruation was observed. There was no evidence of seasonality of estrous cycles with this photoperiod. Testicular measurements of males showed no overt seasonal changes. There was variation in testicular size, and one male copulated at a range of testicular sizes. The data indicate that T. bancanus has estrous cycles similar to those of prosimian primates and some New World monkeys and that these cycles occur throughout the year under constant photoperiodic conditions.
对三对婆罗洲跗猴（Tarsius bancanus）的繁殖状况进行了为期16个月的记录。每对跗猴单独饲养，光照周期恒定（光照：黑暗 = 11.5:12.5），类似于它们原生栖息地的光照周期。对雌性的生殖周期进行了6个月的目视监测，之后又通过阴道涂片和外生殖器测量进行了10个月的监测。发情前期和发情期阴道上皮细胞的逐渐增殖和角质化伴随着外生殖器的增大。周期长度平均为24.0 ± 3.2天。每个周期外生殖器肿胀6 - 9天。交配发生在发情期的第一天，发情期持续1 - 3天。未观察到月经。在这种光照周期下，没有发情周期季节性的证据。雄性的睾丸测量结果未显示明显的季节性变化。睾丸大小存在差异，一只雄性在不同的睾丸大小范围内都有交配行为。数据表明，婆罗洲跗猴的发情周期与原猴亚目灵长类动物和一些新大陆猴的发情周期相似，并且在恒定光照周期条件下全年都会出现这些周期。
