The present study contributes to a growing line of research exploring the associations between physiology and communication behavior. Specifically, this study investigated the influence of testosterone (T) on perceptions of partners' accommodative and nonaccommodative behaviors during a conversation about a relational stressor, and their subsequent association with satisfaction with the conversation. One hundred individuals participated in the study, which included a pre-survey, lab visit, and post-survey. Results revealed that for women, T was negatively associated with perceived partner accommodation and satisfaction with the conversation. Findings uncovered significant mediation effects of women's perceived partner (non)accommodation, while revealing several partner effects. Furthermore, the study found that satisfaction with the conversation was positively predicted by partner accommodation and negatively predicted by partner nonaccommodation for both women and men. These results indicate the utility of communication accommodation theory in examining conflict conversations and imply that T may influence communicative behaviors during conversation about a relational stressor.

We studied the effects of spinal intrathecal fentanyl on oxytocin secretion in 20 healthy women prior to an elective caesarean delivery at term under spinal anaesthesia. The women were randomly allocated into two groups with respect to spinal anaesthesia. Group I (n=10) received intrathecal bupivacaine (15 mg) plus fentanyl (25 microgram), and Group II (n=10) received intrathecal bupivacaine (15 mg) alone, prior to caesarean section. The two groups were comparable demographically. Altogether, ten samples of 4.5 ml of blood (taken every 60 s) were obtained before and ten samples were obtained after the intrathecal administration of the drug and establishment of the T6 block, and plasma oxytocin concentrations were assayed for each subject. Oxytocin was measured by RIA. We found no significant differences in plasma oxytocin concentrations of individual subjects before and after intrathecal injection. In addition, there were no significant differences in plasma oxytocin concentrations between the two groups when pooled samples from the subjects were compared for the pre- and post-intrathecal injection phases. We conclude that the spinal intrathecal administration of fentanyl does not suppress oxytocin secretion in pregnant women who are not in labour at term.
