Discover how testosterone influences leadership, revealing the critical role cortisol plays in status-seeking behavior and executive success.
How Testosterone Shapes Leadership: What the Science Says
Testosterone is linked to leadership-relevant, status-seeking behavior — but its effects are context-dependent and moderated by basal cortisol. That single sentence captures what a decade of peer-reviewed research has converged on, and it matters enormously for how you interpret any headline claiming that high testosterone makes someone a better leader.
The clearest evidence comes from two directions. Mehta and Josephs (2010) demonstrated experimentally that administered testosterone increased status-seeking in men with low basal cortisol, while producing status-loss avoidance in men with high basal cortisol. Van der Meij et al. (2016) extended this to a real-world executive sample and a meta-analysis of nine studies, finding no robust link between basal testosterone alone and holding a leadership position. The interaction with cortisol, not testosterone in isolation, is what predicts attained status.
Key points before you read further:
- Testosterone is not a “leadership hormone.” Its behavioral effects depend heavily on the stress hormone cortisol and on situational cues.
- The dual-hormone hypothesis (Mehta & Josephs) explains most of the inconsistency in earlier research by showing cortisol moderates testosterone’s influence on status-seeking.
- Sex and sample limitations apply. Much early research used male samples; growing evidence from mixed-sex studies suggests the interaction extends to women, though with important nuances.
- Correlation is not causation. Most field studies are correlational; only pharmacological experiments establish causal direction.
Key Takeaways
Testosterone’s role in leadership is real but conditional: the dual-hormone interaction with cortisol, not testosterone alone, predicts status-seeking and attained leadership outcomes.
| Point | Details |
|---|---|
| Dual-hormone interaction | Testosterone predicts status-seeking only when basal cortisol is low; high cortisol suppresses this effect. |
| Basal testosterone alone is weak | Meta-analysis across nine studies found no robust link between basal testosterone and holding a leadership position. |
| Empathy trade-off | Higher testosterone is negatively associated with empathic accuracy, which can reduce perceived leadership ability. |
| Measurement matters | Sampling time, media type, and cortisol co-measurement materially change what hormone studies find. |

What is the role of testosterone in leadership research?
Testosterone is produced primarily in the testes in men and the ovaries and adrenal glands in women, regulated by the hypothalamic-pituitary-gonadal (HPG) axis. Cortisol, the body’s primary stress hormone, is governed by the hypothalamic-pituitary-adrenal (HPA) axis. These two systems interact in ways that shape social behavior, and understanding both is necessary to interpret any hormone-leadership study.
Measurement basics researchers rely on:
- Basal vs. reactive sampling. Basal testosterone reflects a person’s stable, resting hormone level, typically measured in the morning before any task. Reactive sampling captures short-term fluctuations in response to competition, social challenge, or stress.
- Saliva vs. serum. Salivary sampling is non-invasive and practical for field studies; serum (blood) measures total testosterone more precisely. Salivary assays capture free (biologically active) testosterone but are sensitive to collection protocol errors.
- Diurnal rhythm. Testosterone peaks in the early morning and declines through the day, so a sample taken at 3 PM is not comparable to one taken at 8 AM. Studies that ignore this introduce noise that can obscure real effects.
- Single sample vs. repeated measures. A single hormone snapshot carries substantial within-person variability. Repeated measures or averaged samples produce more reliable estimates of basal levels.
These protocol choices are not minor details. Research published on PubMed Central confirms that participant selection, sampling timing, and media type materially affect observed hormone-leadership relationships, which helps explain why studies using different methods often reach different conclusions.
What does peer-reviewed research actually find?
The evidence base spans correlational field studies, pharmacological experiments, and meta-analyses. Each design offers different leverage on the question of whether testosterone influences leadership.
-
Mehta & Josephs (pharmacological experiment, n = 115). This is the strongest causal evidence available. In a randomized design, exogenous testosterone increased status-seeking in low-cortisol men but produced status-loss avoidance in high-cortisol men, with effects further shaped by opponent-status cues. Because participants were randomly assigned to testosterone or placebo, this study establishes a causal pathway, not just a correlation.
-
Harvard Kennedy School executive field study. In a real-world executive sample, endogenous testosterone predicted number of subordinates only among executives with low basal cortisol. Among high-cortisol executives, the testosterone-status relationship disappeared. This is correlational, but the sample of actual leaders gives it strong ecological validity.
-
Van der Meij et al. (2016) field study and meta-analysis. Across a field sample and a meta-analysis spanning nine studies (n ≈ 1,103), basal testosterone was not reliably associated with holding a managerial position. Higher basal testosterone did predict a more authoritarian leadership style in non-managers, but that effect did not extend to current managers. The meta-analytic signal is notably mixed.
-
Goll et al. (2023), Scientific Reports. A more recent study found that testosterone related to leadership-relevant behaviors across contexts, with cortisol moderating those effects under risk conditions, and crucially, the interaction extended to both male and female participants. This is one of the first studies to report the testosterone-cortisol interaction in mixed-sex leadership contexts.
-
Broader review evidence. A PMC review confirms that testosterone is linked to dominance and risk-taking, but findings are heterogeneous across tasks, populations, and measurement approaches. Publication bias and small samples in some experiments mean the true effect size for testosterone alone is likely smaller than early studies suggested.
The pattern across these studies is consistent: testosterone alone is a weak and unreliable predictor of leadership position or effectiveness. The interaction with cortisol, and the situational context, is where the real signal lives.
How does the dual-hormone hypothesis explain testosterone’s effects?
The dual-hormone hypothesis, developed by Mehta and Josephs and elaborated in subsequent work, offers the clearest framework for understanding why testosterone’s effects on status-seeking are so variable. The core logic is straightforward.
How the interaction works:
- Low cortisol + high testosterone: The stress axis is calm, and the reproductive/status axis is active. Under these conditions, testosterone promotes approach-oriented status-seeking, competitive engagement, and willingness to challenge higher-status individuals.
- High cortisol + high testosterone: The stress axis is activated, signaling threat or resource scarcity. Testosterone-driven status motivation is suppressed or redirected toward protecting existing status rather than pursuing new gains, a pattern Mehta and Josephs call “status-loss avoidance.”
- Low testosterone regardless of cortisol: Status motivation is generally reduced; neither pattern dominates.
The pharmacological study by Mehta and Josephs illustrates this cleanly. Men given exogenous testosterone who also had low basal cortisol became more competitive against high-status opponents. Men given the same testosterone dose but with high basal cortisol became more avoidant. Same hormone, opposite behavior, because the cortisol context changed the meaning of the testosterone signal. The dual-hormone hypothesis explains most of the inconsistency in earlier research that treated testosterone as a simple, linear predictor.
Context matters beyond just cortisol levels. Perceived opponent status, task stakes, and whether the environment signals threat or opportunity all shape how testosterone-linked motivation is expressed.
Pro Tip: If you are evaluating your own hormone levels, a single testosterone reading without a concurrent cortisol measurement tells you only half the story. Ask your provider about a comprehensive panel that includes both.
What biological mechanisms connect testosterone to leadership behaviors?
Testosterone does not flip a “leadership switch.” It modulates several overlapping neural and behavioral systems, each of which can support or undermine effective leadership depending on the situation.
Plausible mechanisms supported by research:
- Reward sensitivity and approach motivation. Testosterone appears to increase sensitivity to reward cues and reduce sensitivity to punishment signals, which can translate into greater willingness to take initiative and pursue status-relevant goals.
- Social approach vs. avoidance circuits. Higher testosterone is associated with reduced threat-sensitivity in social hierarchies, making individuals more likely to approach rather than withdraw from competitive or high-stakes social situations.
- Risk-taking pathways. Testosterone correlates with greater risk tolerance in financial and social decisions, which can be adaptive in entrepreneurial or high-stakes leadership contexts but maladaptive in situations requiring caution.
- Dominance and authoritarian style. The Van der Meij meta-analysis found higher basal testosterone predicted more authoritarian style in non-managers, suggesting the hormone may push toward directive rather than collaborative approaches.
The trade-off that often gets overlooked: higher endogenous testosterone is negatively associated with empathic accuracy, measured both in laboratory tasks and in 360-degree field assessments. Reduced empathic accuracy, in turn, affects how others perceive a person’s leadership ability. Dominance and empathy are not simply additive in leadership; they can pull in opposite directions, and testosterone tends to weight the scales toward dominance.
Pro Tip: Dominance-oriented leadership tends to perform well in hierarchical, time-pressured tasks with clear authority structures. In collaborative, creative, or psychologically safe team environments, the same style often backfires. Understanding your hormonal profile is only useful if you also understand the demands of your specific leadership context.
Why do different studies reach different conclusions about hormones and leadership?
Method choices drive a surprising share of the variance in findings across hormone-leadership studies. Before accepting any study’s conclusion, consider these protocol factors.
Sampling protocol issues:
- Morning vs. evening collection changes baseline testosterone values substantially due to diurnal rhythm.
- A single saliva sample has high within-person variability; studies using only one sample underestimate reliability.
- Serum measures total testosterone; saliva captures free testosterone. These are not interchangeable, and the biologically active fraction matters most for behavior.
- Reactive samples taken after a stressful task measure a different construct than basal samples taken at rest.
Common confounds that distort results:
- Age and sex. Testosterone declines with age in men; women have lower absolute levels but may show proportionally similar behavioral effects. Studies that do not stratify by age or sex conflate very different populations.
- Medications. Oral contraceptives, corticosteroids, and some antidepressants alter both testosterone and cortisol levels, creating noise in samples that do not screen for these.
- Chronic stress and social rank. Chronic stress elevates basal cortisol, which suppresses testosterone. A person in a high-stress organizational environment may show low testosterone not because of biology but because of their work conditions.
- Sample composition. Student samples and executive samples are not interchangeable. Status hierarchies, competitive stakes, and baseline hormone levels differ substantially between a college laboratory and a C-suite.
The methodological takeaway: weight studies that control for cortisol, use repeated hormone measures, and report real-world outcomes (such as number of subordinates or performance ratings) more heavily than single-sample, student-only designs. Measurement practices and participant selection materially affect observed hormone-leadership relationships, and the field is still working toward standardized protocols.
What should individuals and organizations actually do with this evidence?
The research supports a few responsible conclusions. It does not support using hormone levels to select leaders, predict leadership potential, or prescribe testosterone as a performance enhancer.
For individuals:
- Focus on stress management as a primary lever. Reducing chronic cortisol through sleep, exercise, and recovery creates the low-cortisol context in which testosterone-linked status motivation tends to express most adaptively.
- If you are curious about your hormone levels, pursue clinical evaluation rather than self-interpretation. A single number from a consumer test kit is not actionable without clinical context.
- Avoid self-prescribing testosterone to enhance leadership performance. There is no peer-reviewed evidence that exogenous testosterone improves leadership outcomes in people with normal levels, and the risks of unsupervised use are real.
For organizations:
- Do not use hormone testing in hiring or promotion decisions. The science does not support it, and the ethical and legal risks are significant.
- Invest in organizational stress reduction. The Harvard Kennedy School executive study suggests that low-cortisol environments may allow testosterone-linked status motivation to express more productively, which is an argument for reducing chronic workplace stress, not for selecting high-testosterone employees.
- Design advancement pathways that reward collaborative and empathic leadership alongside directive styles. Given the empathy trade-off associated with higher testosterone, organizations that value only dominance-oriented leadership may systematically undervalue effective leaders.
Ethical note: Testing or manipulating hormones for leadership selection is scientifically unwarranted given current evidence and raises serious ethical concerns about biological determinism, privacy, and discrimination. The research describes population-level tendencies, not individual destinies.
When should you consider clinical testing for low testosterone?
The science of testosterone and leadership is distinct from the clinical question of whether your testosterone levels are affecting your health and well-being. Low testosterone (hypogonadism) is a medical condition with recognized symptoms, and it warrants clinical evaluation, not self-diagnosis.
Common symptoms that suggest evaluation is appropriate:
- Persistent fatigue not explained by sleep or lifestyle factors
- Reduced libido or sexual dysfunction
- Loss of muscle mass or increased body fat despite consistent exercise
- Mood changes, including increased irritability or low motivation
- Cognitive changes such as difficulty concentrating
What a clinical evaluation typically includes:
- Total testosterone: Measured from a morning blood draw (ideally between 7 and 10 AM) to capture peak levels.
- Free testosterone: The biologically active fraction; important when total testosterone is borderline.
- Repeat testing: A single low reading is not sufficient for diagnosis; most guidelines recommend confirming with a second morning sample.
- Cortisol assessment: Clinically indicated when fatigue, stress, or adrenal symptoms are present alongside low testosterone, since the two axes interact.
- Additional panel components: LH, FSH, SHBG, and a metabolic panel help identify the cause and guide treatment decisions.
Pro Tip: A comprehensive hormone panel that includes both testosterone and cortisol gives your provider a much clearer picture than testosterone alone. Ask specifically about morning timing and whether free testosterone will be included.

A clinician’s perspective on using this research responsibly
The testosterone-leadership literature is genuinely fascinating, and it is also genuinely easy to misuse. What strikes me most about the evidence is how consistently the dual-hormone interaction outperforms testosterone alone as a predictor, yet how rarely that nuance makes it into popular coverage. Executives and high-achieving professionals who come in asking about their testosterone levels often arrive with a simplified mental model: more testosterone equals more drive, more status, more leadership. The research simply does not support that framing.
What the evidence does support is this: chronic stress, through elevated cortisol, can suppress the very hormonal conditions under which testosterone-linked motivation expresses most adaptively. That is a clinically meaningful finding. Addressing hormone imbalance through medically supervised evaluation and, where clinically indicated, bioidentical hormone replacement therapy, is about restoring physiological balance, not engineering a leadership profile. The distinction matters. At evoyouthful, we evaluate patients comprehensively, consider the full hormonal picture including cortisol, and recommend treatment only when there is a clinical basis for it. The goal is your well-being, not a performance optimization experiment.
