Physiology
Testosterone
A steroid hormone primarily produced in testes (males) and ovaries (females). Drives development of male characteristics, muscle growth, and influences behavior including aggression and risk-taking.
Biological Context
Testosterone levels fluctuate with competition, status, and social context. Winning raises testosterone; losing lowers it. High testosterone correlates with risk-taking and dominance-seeking.
Business Application
Organizational testosterone: the drive for dominance, risk-taking, and aggressive competition. High-testosterone cultures pursue market dominance aggressively.
