ReportChanges in saliva testosterone after psychological stimulation in men
Abstract
Saliva testosterone (ST) concentration was measured in 20 young adult and healthy men before, during and after the presentation of five different films. The films were selected to provoke erotic, sexual, aggressive, stressful and neutral stimulation, respectively. An increase in ST was found 15 min after the onset of both the erotic and the sexual stimulation, while a decline of ST levels was observed during the stressful movie showing dental surgery. No changes were found for either the neutral or the aggressive stimulant. Furthermore, no differences were found between ST levels before and after the showing of any of the films. Thus, saliva testosterone responds quickly to psychological stimulation, and may provide a practical alternative to testosterone measurements in serum under psychological test situations.

Testosterone's role in modulating human behaviors relevant to mating and parenting
2024, Frontiers in NeuroendocrinologyTestosterone (T) is linked to human mating and parenting. Here, we comprehensively reviewed evidence on whether, in men and women, (1) basal T levels are related to mating and parenting behaviors, (2) T responds to reproduction-relevant cues, (3) acute changes in T map onto subsequent mating and parenting behaviors, and (4) single-dose exogenous T administration causally affects mating and parenting behaviors. We examined whether the available evidence supports trade-off interpretations of T’s adaptive function whereby high T levels correspond to greater mating/reproductive effort and competition and low T levels to greater parenting effort and nurturance. We found mixed support for trade-off hypotheses, suggesting that T’s function in modulating human mating and parenting might be more nuanced and highly dependent on context and individual trait differences. Results were largely similar for men and women, although studies with women were scarcer than those with men for most behaviors we reviewed.
Mating-related stimuli induce rapid shifts in fathers' assessments of infants
2024, Evolution and Human BehaviorA common life history theory trade-off is that which males face between mating effort and parental effort. This trade-off is observed across species, among individuals within a species, and within individuals across their lifespan. Recent studies suggest the possibility of more rapid trade-offs or motivational shifts in response to transient aspects of the social environment. We were interested in whether exposure to mating-related stimuli would negatively impact men's evaluation of parental-related stimuli and vice-versa, and whether this response would differ between fathers and non-fathers. In two separate experiments, a total of 160 heterosexual or bisexual men rated how appealing they found 40 images of attractive infants and 40 images of attractive adult females. Half of all participants viewed infant images before viewing female images, and the other half viewed female images before infant images. In both experiments, fathers rated infant stimuli as more appealing than did non-fathers when infants were presented before females, but not when infants were presented after females. That is, priming fathers with female stimuli negatively impacted their ratings of infants. On the other hand, priming men with pictures of cute infants before viewing females did not impact ratings of female pictures, in either fathers or non-fathers. Nor did priming fathers with pictures of another highly rewarding stimulus - highly appealing foods - decrease their ratings of infants. The negative effect of female pictures on fathers' subsequent ratings of infant stimuli is consistent with the possibility that the female pictures activated motivational systems related to mating effort, which in turn inhibited motivational systems related to parental effort, rendering the infant stimuli less appealing. Our findings suggest that human fathers may be susceptible to transient shifts in life history strategy as a function of their immediate social environment.
Maternal steroids during pregnancy and their associations with exposure to lifetime stressful life events, prenatal stress appraisal and psychological functioning
2023, PsychoneuroendocrinologyDuring pregnancy, steroids enable physiological adaptations in response to many factors, including maternal stress or psychological functioning. While stress and psychological dysfunction can have endocrine-disrupting effects beyond cortisol disruption, associations between prenatal maternal stress or related psychological dysfunction and the broader steroid milieu remain understudied.
To assess associations between independent and joint maternal stress and psychological functioning measures and steroid profiles in pregnancy (22–40 gestational weeks) in the Programming of Intergenerational Stress Mechanisms (PRISM) birth cohort (n = 334).
Serum metabolomics detected 42 steroids and their metabolites, which were grouped into five classes (pregnenolone, androgens, estrogens, progestin, and corticosteroids). The Perceived Stress Scale, Life Stressor Checklist-Revised, and Edinburgh Postnatal Depression Scale indexed lifetime traumatic/non-traumatic stressors, global prenatal stress appraisal, and depressive symptoms during pregnancy, respectively. Exposures were categorized as high-low using the corresponding 3rd quartiles. We assessed associations between both individual and joint stress exposures with steroid classes using linear mixed effect models and with individual steroids using linear regressions. We also examined fetal sex-specific effects.
High prenatal perceived stress was independently associated with lower levels of androgens and estrogens in the overall sample [β (95%CI): androgens: −0.13 (−0.25;−0.01); estrogens: −0.16 (−0.31;−0.01)], particularly among women carrying males [androgens: −0.22 (−0.39;−0.05); estrogens: −0.28 (−0.50;−0.07)]. Results on estrogens were consistent when considering joint exposure to both greater lifetime stressors and higher prenatal perceived stress. We also found a single testosterone metabolite—5alpha-androstan-3alpha,17alpha-diol disulfate—negatively associated with both individual high perceived stress and joint exposure to high lifetime stressors and high perceived stress among women carrying males.
Increased maternal perceived stress experienced in pregnancy was independently associated with lower maternal androgen and estrogen levels during pregnancy in the overall sample, particularly among women carrying males. Results on estrogens were consistent when we considered the joint exposure of increased lifetime stressors and higher prenatal perceived stress.
Sexual incentive motivation, sexual behavior, and general arousal: Do rats and humans tell the same story?
2022, Neuroscience and Biobehavioral ReviewsSexual incentive stimuli activate sexual motivation and heighten the level of general arousal. The sexual motive may induce the individual to approach the incentive, and eventually to initiate sexual acts. Both approach and the ensuing copulatory interaction further enhance general arousal. We present data from rodents and humans in support of these assertions. We then suggest that orgasm is experienced when the combined level of excitation surpasses a threshold. In order to analyze the neurobiological bases of sexual motivation, we employ the concept of a central motive state. We then discuss the mechanisms involved in the long- and short-term control of that state as well as those mediating the momentaneous actions of sexual incentive stimuli. This leads to an analysis of the neurobiology behind the interindividual differences in responsivity of the sexual central motive state. Knowledge is still fragmentary, and many contradictory observations have been made. Nevertheless, we conclude that the basic mechanisms of sexual motivation and the role of general arousal are similar in rodents and humans.
A positive relationship between body height and the testosterone response to physical exercise
2021, Evolution and Human BehaviorHuman male height is one of the most conspicuous sexually dimorphic, phenotypic characteristics that affect how men are perceived both by men and women, impacting mate selection and intra-sexual competition. Testosterone is a key hormone linked to morphological masculinity and advantage in intra-sexual competition. To date, there have been limited studies linking height with testosterone levels. Here, we examined the change in circulating testosterone levels after physical exercise in 97 healthy and physically active men. Our results show that there was a significant relationship between male stature and the change in testosterone levels, whereas there was no such link between body height and circulating testosterone levels. Therefore, our findings provide evidence that height may indicate male’s adaptive capabilities to physiologically mobilize their bodies when it is needed and/or beneficial.
How to alleviate the agony of providing negative feedback: Emotion regulation strategies affect hormonal stress responses to a managerial task
2021, Hormones and BehaviorProviding negative feedback can be demanding, as it typically requires dealing with multiple negative emotions. The first aim of this study was to transfer this work-related task to a new laboratory protocol and to investigate short-term hormonal changes among feedback providers. The second aim was to test if such hormonal stress responses can be attenuated through a priori instructions on how to regulate emotions.
Each of 150 participants (51% women) provided eight saliva samples before, during, and after anticipating and conducting a negative feedback conversation with a professional actor who displayed negative emotional reactions. Participants were divided into four conditions regarding the way they were instructed to regulate their emotions: expressive suppression (keeping a neutral expression); cognitive reappraisal (staying task-oriented and emotionally distanced); affect utilization (moving towards and using emotions); or control condition.
By means of three-phase spline growth models, latent growth factors during baseline, stress response, and recovery were specified. Providing negative feedback was followed by significant temporary testosterone decreases as well as cortisol increases. Testosterone (but not cortisol) responses were attenuated when feedback providers had been instructed to either follow a cognitive reappraisal or affect utilization strategy.
This study provides evidence that a typical managerial task, that is, having to provide negative feedback, is a testosterone- and cortisol-relevant experience. Down-regulation of an individual's emotional involvement through reappraisal, as well as the newly introduced technique of moving towards and making use of the interaction partner's emotions (affect utilization), revealed consequences in terms of attenuating the testosterone response to stress.
