Testostrn

  • Testosterone’s role is shaped by evolutionary biology, not just modern environment.

• It influences male development from the womb through adulthood.

• Drives formation of male physical traits (muscle, bone, reproductive organs).

• Affects brain development, contributing to average sex-based behavioral differences.

• Behavioral effects evolved due to selection pressures (competition, mating, survival).

• Expression of testosterone’s effects varies based on genetics, environment, and life history.
