Pheromonal signals from the dominant female marmoset monkey were implicated in maintaining the suppression of LH secretion and ovulation in socially subordinate females. When subordinate, and reproductively suppressed, female marmoset monkeys were removed from their group without scent contact with their dominant females, subordinate females in control group 1 (N = 8) and control group 2 (N = 5), ovulated 10.8 +/- 1.4 days and 10.4 +/- 0.8 days respectively (mean +/- s.e.m.) after separation. Subordinate females (N = 8) removed from their dominant female and group, but maintained in scent contact only with their dominant females, showed a delay in the onset of ovulation (31.0 +/- 6.4 days) compared with control groups 1 and 2. Plasma LH concentrations of subordinate females during the scent transfer phase were lower than in controls without scent transfer and comparable to those seen whilst the females were subordinates in groups. Contact of subordinate females with olfactory stimuli from dominant females therefore maintains the suppression of both LH secretion and ovulation in socially subordinate female marmosets. Such pheromonal cues provide evidence of a quantifiable link between dominant female marmosets and the maintenance of physiological suppression of reproduction in their female subordinates.
来自占主导地位的雌性狨猴的信息素信号被认为与维持对处于社会从属地位的雌性狨猴促黄体生成素（LH）分泌和排卵的抑制有关。当处于从属地位且生殖功能受到抑制的雌性狨猴被从其群体中移出，且与占主导地位的雌性狨猴没有气味接触时，对照组1（N = 8）和对照组2（N = 5）中的从属雌性狨猴在分离后分别于10.8±1.4天和10.4±0.8天排卵（平均值±标准误）。从占主导地位的雌性狨猴和群体中移出，但仅与占主导地位的雌性狨猴保持气味接触的从属雌性狨猴（N = 8），与对照组1和2相比，排卵开始出现延迟（31.0±6.4天）。在气味传递阶段，从属雌性狨猴的血浆LH浓度低于没有气味传递的对照组，且与这些雌性狨猴在群体中处于从属地位时的浓度相当。因此，从属雌性狨猴与来自占主导地位的雌性狨猴的嗅觉刺激接触，维持了对处于社会从属地位的雌性狨猴LH分泌和排卵的抑制。这种信息素线索提供了证据，证明占主导地位的雌性狨猴与维持对其雌性从属狨猴生殖的生理抑制之间存在可量化的联系。
