从属的雌性绒猴保持无排卵，并有低血浆浓度的促黄体激素（LH）时，保持与他们的优势女性。来自占主导地位的雌性的嗅觉线索与维持这种生殖抑制有关。接受犁鼻器消融（一种辅助嗅觉器官; n = 3）、主嗅上皮消融（n = 4）或两种病变（n = 5）的从属雌性动物在随后7周内与其优势雌性动物一起饲养时不排卵。一处或两处病变后的血浆LH浓度与病变前浓度相似。嗅觉病变（经组织学和行为学试验验证）并不损害生殖活动，嗅觉病变占主导地位的女性进行卵巢周期相似的持续时间完整的占主导地位的女性。受损的从属雌性（n = 6），仅与其主导雌性保持视觉接触，组排卵29.1 +/- 9.3天（平均值+/- SEM）与占主导地位的雌性动物分离后;第一次排卵明显延迟（P < 0.05）与完整的从属雌性动物完全与它们的主导雌性动物和组（10.8 +/-1.3天，n = 8）相比较。行为和视觉线索连同嗅觉似乎都发挥重要作用，在维持下属雌性绒猴的排卵抑制。
Subordinate female marmoset monkeys remain anovulatory and have low plasma concentrations of luteinizing hormone (LH) when maintained with their dominant females. Olfactory cues from the dominant female have been implicated in maintaining this reproductive suppression. Subordinate females that received either ablation of the vomeronasal organ (an accessory olfactory organ; n = 3), ablation of the main olfactory epithelium (n = 4), or both lesions (n = 5) did not ovulate in the following 7 weeks while housed with their dominant female. Plasma LH concentrations following either or both lesions were similar to pre-lesion concentrations. Olfactory lesions (verified by histological and behavioural trials) did not impair reproductive activity, as olfactory-lesioned dominant females underwent ovarian cycles of similar duration to intact dominant females. Lesioned subordinate females (n = 6), maintained in visual-only contact with their dominant female and group ovulated 29.1 +/- 9.3 days (mean +/- SEM) after physical separation from their dominant females; this first onset of ovulation was significantly delayed (P < 0.05) compared with intact subordinate females completely isolated from their dominant females and group (10.8 +/- 1.3 days, n = 8). Behavioural and visual cues together with olfaction all appear to play important roles in maintaining the suppression of ovulation in subordinate female marmoset monkeys.
