In order to clarify this inconsistent correlational evidence, we provide a direct causal test of testosterone’s impact on cortisol and negative affect responses to stress using a status-relevant social stressor. Further, the few correlational studies that have examined testosterone and social stress have provided mixed evidence linking testosterone levels to both increased (Juster et al., 2016) and decreased (Stephens et al., 2016) cortisol output. Compared to placebo, testosterone significantly increased cortisol and negative affect in response to the stressor, especially for men high in trait dominance (95% confidence intervals did not contain zero). Your body responds to the demands you place on it by optimizing hormone levels to meet those demands. Establishing consistent sleep patterns and creating an optimal sleep environment should be the foundation of any hormone support strategy. Quality sleep is perhaps the most critical factor, as testosterone production primarily occurs during deep sleep stages. Individuals with documented hormone deficiencies identified through blood testing might be candidates for pregnenolone supplementation as part of a comprehensive hormone optimization plan. Usually, a small amount of circulating testosterone is transformed into estradiol, which is a type of estrogen.

During danger, cortisol takes control to aid survival, such as running away from danger. This is quite true for many contexts, but it varies based on factors such as type of stress and age. Studies have shown that stress, in short bursts, can be good for us, such as when we stay awake to finish our tasks or to handle danger. Tough individuals are more inclined to have higher dopamine levels and strong serotonin signaling. A resilient individual shows better regulation of the hypothalamic-pituitary-adrenal (HPA) axis and can quickly return to normal conditions after stress. Diets high in processed foods, sugar, and unhealthy fats promote stress and hormonal imbalance, while diets rich in whole foods, lean proteins, healthy fats, fruits, and vegetables support balance. But when stress persists, cortisol levels remain elevated, and testosterone production begins to suffer. It activates the "fight or flight" response, releasing hormones like cortisol and adrenaline that prepare the body to respond to immediate danger. But what many people don’t realize is that chronic stress is one of the most significant contributors to lowering testosterone levels. The cortisol helps the body stay on high alert; once the threat passes the parasympathetic nervous system will reduce the SNS response to return to optimal hormone balance. Past studies have looked at how these hormones relate to behavior and physiological stress responses, but little was known about how they affect the subjective experience of stress. High levels of trait dominance, marked by a propensity to use force, fear, or intimidation to gain high-ranking positions within social groups (Cheng et al., 2013), correlate with increased cardiovascular stress reactivity (Lee & Hughes, 2014) and accentuate the behavioral effects of testosterone in status-relevant situations. Despite this correlational evidence, the causal effects of testosterone on responses to status-relevant social stress have not been adequately tested in healthy young adults1. Yet other studies indicate that testosterone correlates with increased cortisol and negative affect in response to situations that threaten social status, like losing a competition (Mehta et al., 2008; Zilioli & Watson, 2013) or being relegated to a low-ranking social position (Josephs et al., 2006).
