Episode notes
Testosterone Reacts Rapidly To Context
- Men's testosterone is highly dynamic and reacts to immediate environmental cues like competition and attraction.
- Sarah Hill explains testosterone peaks in the morning, falls by evening, and rises or falls after wins, losses, job stress, or presence of attractive people.
Women's Hormones Follow Predictable Cycles
- Female primary sex hormones are largely cyclical and predictable because ovaries drive follicle maturation, ovulation, and corpus luteum progesterone release.
- Sarah Hill says knowing a woman's age and cycle start date gives good certainty about her hormone state, unlike men.
Testosterone Has A Morning Peak And Signals Status
- Testosterone also follows a circadian rhythm, peaking in the morning and declining by evening.
- Sarah Hill frames testosterone as a signal from the brain to the endocrine system that increases when things go well and decreases when they go poorly.
