Salivary Hormonal Responses Related to Menstrual Cycle
Menstrual cycle phase predicts women’s hormonal responses to sexual stimuli. Author: Shirazi TN, et al. (2018), Horm Behav. ABSTRACT: A robust body of research has demonstrated shifts in women’s sexual desire and arousal across the menstrual cycle, with heightened desire and arousal coincident with heightened probability of conception (POC), and it is likely that ovarian hormones modulate […]
Salivary Stress Biomarkers May be a Useful Tool for Determining the Risk of Stress Maladaptation
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Author: Hellewll SC & Cernak I. (2018), J Trauma Stress. ABSTRACT Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas […]
Sex hormone variations in both sexes may be important when investigating stress physiology
Sex hormones adjust “sex-specific” reactive and diurnal cortisol profiles. Author: Author: Juster, et al (2015), Psychoneuroendocrinology Sex differences in stress hormone functions are presumed to depend on sex hormones. And yet, surprisingly few psychoneuroendocrine studies actually assess within-sex variations of testosterone, estradiol, and progesterone when investigating sex-specific activities of the hypothalamic-pituitary-adrenal axis. In this methodological […]
40 years of testosterone in biosociology research
Testosterone in biosociology: A memoir Author: Mazur (2016), Hormones and Behavior The author looks back at his four decades of research on testosterone in the context of biosociology – its accomplishments, pitfalls, outstanding questions, and future directions. View Abstract Keywords: Testosterone
Salivary bioscience enables anabolic hormone profiles in elite military men
Anabolic hormone profiles in elite military men. Author: Taylor MK, et al (2016), Steroids. This study recently characterized the awakening responses and daily profiles of the catabolic stress hormone cortisol in elite military men. Anabolic hormones follow a similar daily pattern and may counteract the catabolic effects of cortisol. This companion report is the first […]
Salivary testosterone / salivary cortisol ratio may predict a team player’s social popularity
Long-term stability of diurnal salivary cortisol and alpha-amylase secretion patterns Author: Ponzi D, et al (2016), Psychoneuroendocrinology This study tested whether testosterone and cortisol interacted in predicting social network centrality. The sample size consisted of 41 male rugby athletes from Burnaby, Canada. Using social network analysis (SNA), three measures of centrality were investigated: popularity (i.e., […]
Differences in Salivary Cortisol and Testosterone may guide social network dynamics
Cortisol and testosterone associations with social network dynamics Author: Kornienko, et al (2015), Psychoneuroendocrinology. This study integrates behavioral endocrinology and network science to explore links between hormones and social network dynamics. Specifically, we examine how cortisol (C) and testosterone (T) are associated with creation of new friendships and maintenance of existing friendships. A collegiate marching […]
