Primates are social species whose reproduction is influenced by their social relationships. The cotton-top tamarin, Saguinus oedipus, and the common marmoset, Callithrix jacchus, are cooperative breeding species where the family structure alters their reproductive function in many ways. While primates receive social effects on reproduction via all sensory stimuli, the marmosets and tamarins are particularly influenced by olfactory or chemosensory stimuli. A number of studies will be presented to show both the stimulatory and suppressive influences on reproductive events for both males and females. For instance, within 20 - 30 minutes male marmosets show increased serum testosterone following exposure to the scent of an ovulatory female while they have depressed serum testosterone responses when presented with the scent of their own young infant. Neural mechanisms will be presented demonstrating the pathways that process the social stimuli to influence both hormonal and behavioral responses to the stimuli.
