Communication Patterns Among Male Couples with Open and Monogamous Agreements.

Male couples in open relationships tend to have as equally fulfilling relationships as monogamous male couples; however, less is known about communication differences between monogamous and open couples. Because couples with open agreements permit sex with outside partners, they must navigate different relationship issues than monogamous couples, and this can translate to differences in communication. We therefore examined differences between cisgender men in monogamous versus open relationships regarding communication about sexual agreements, safety agreements, breaking of sexual and safety agreements, the disclosure of broken sexual and safety agreements, and general relationship communication. Using a sample of 395 couples, we found that while certain aspects of communication are different for monogamous couples compared to open couples, similarities also exist. Specifically, we identified no differences in how explicitly couples discussed their sexual and safety agreements, attitudes toward communication about safety agreements, and mutual avoidance and withholding communication. However, monogamous couples had more positive attitudes toward communication about sexual agreements. The results were mixed on the perceived impact that broken safety agreements had on communication with the primary partner. Our results are interpreted with attention to relationship well-being and implications for safer sex practices.

Longitudinal associations between prenatal testosterone and postpartum outcomes in a sample of first-time expectant lesbian couples.

Although increasing numbers of gay and lesbian individuals ultimately become parents, the vast majority of research on the transition to parenthood focuses exclusively on heterosexual samples. Even less is known about the physiological implications of this major life transition among those who identify as sexual minorities. The present study begins to redress these gaps in the literature by assessing prospective links between prenatal testosterone, a steroid hormone that is negatively associated with nurturance and caregiving, and postpartum outcomes in a sample of 25 first-time expectant lesbian couples (N = 50 individuals). Consistent with prior work in heterosexual samples, which suggests that lower testosterone promotes both partnering and parenting, we found that, in both partners, lower testosterone during the prenatal period predicted better romantic relationship and parenting outcomes at three-months postpartum (e.g., higher relationship quality, more time spent doing baby care). There was also evidence for dyadic associations; for instance, birth mothers reported more overprotective behavior, and non-birth mothers reported greater commitment, when their female partners had lower testosterone. Together, our findings contribute important new knowledge about the functionality of testosterone in close relationships contexts, including some of the first evidence among sexual minorities.

Adult attachment and testosterone reactivity: Fathers' avoidance predicts changes in testosterone during the strange situation procedure.

We assessed parents' testosterone reactivity to the Strange Situation Procedure (SSP), a moderately stressful parent-infant interaction task that pulls for parental nurturance and caregiving behavior. Parents (146 mothers, 154 fathers) interacted with their 1-year-old infants, and saliva samples were obtained pre- and post-task to assess changes in testosterone. We examined whether testosterone reactivity differed between mothers and fathers, the extent to which parents' characteristic approaches to closeness (i.e., adult attachment orientation) contributed to testosterone changes, and whether any influences of adult attachment orientation were independent of more general personality characteristics (i.e., the Big Five personality dimensions). Results revealed that mothers and fathers showed comparable declines in testosterone during the SSP, and that these declines were attenuated among fathers with a more avoidant attachment orientation (i.e., those less comfortable with closeness). Associations between fathers' avoidance and testosterone reactivity were statistically independent of broader personality traits. Our findings provide some of the first evidence for short-term changes in both mothers' and fathers' testosterone in contexts that pull for nurturance. Moreover, these findings demonstrate that individual differences in adult attachment may play an important role in understanding such changes. We discuss possible explanations for gender differences in associations between adult attachment and parents' testosterone reactivity, and the extent to which testosterone reactivity might be sensitive to changes in context for mothers versus fathers.

Closeness-inducing discussions with a romantic partner increase cortisol and testosterone.

Despite progress in understanding the social neuroendocrinology of close relationship processes, most work has focused on negative experiences, such as relationship conflict or stress. As a result, much less is known about the neuroendocrine implications of positive, emotionally intimate relationship experiences. In the current study, we randomly assigned 105 dating or married couples to a 30-minute semi-structured discussion task that was designed to elicit either high or low levels of closeness. Participants provided pre- and post-task saliva samples (to assess cortisol and testosterone) and post-task reports of self-disclosure, closeness, attraction, positive and negative affect, and stress. Participants found the discussion conditions comparably positive and enjoyable, but those in the high-closeness condition reported that they disclosed marginally more and felt marginally closer to their partners than those in the low-closeness condition. Participants also showed larger increases in cortisol and testosterone during the high (versus low) closeness discussion, and self-reported disclosure mediated these increases in cortisol and testosterone. Self-reported closeness and other theoretically plausible mediators, such as sexual attraction and excitement, did not mediate changes in either hormone. Taken together, the current findings contribute to our understanding of neuroendocrine changes associated with emotionally intimate relationship experiences. We consider possible explanations for the hormone changes we observed and offer directions for future research on the neuroendocrine implications of close relationship experiences.
