Abstract

Oxytocin (OT) is a neuropeptide that plays a role in social behaviour and reproduction in humans. Non-invasive OT levels in saliva have recently piqued the interest of researchers because they do not require a specialised medical setting. We tracked OT concentration changes in one woman's basal serum and saliva OT from pregnancy to one year postpartum. We looked at how salivary OT levels changed over time in response to maternal physiological and behavioural responses. During pregnancy and breastfeeding, the fluctuation of saliva OT levels is well correlated with serum OT. However, while salivary OT increased rapidly during direct interaction with the infant (social interaction tests) and/or when the mother watched her own infant's video (video tests), there was no increase in serum. To clarify these single-subject results, we used social interaction and video tests on a group of mothers (nine for social interaction and six for video testing). The mothers had increased OT in their saliva but not in their serum in both tests. Our findings suggest that salivary samples can reflect not only physical but also emotional states, and that saliva samples can be used to monitor women's OT levels during the pre- and postpartum periods.
