How to Optimize Testosterone & Estrogen

In this episode, I discuss testosterone and estrogen hormones and how they impact the brain, body, and behavior after puberty. I also discuss how various behaviors such as exercise (resistance and endurance training) and sex or observing sex impact these hormones and their levels. I ask: "what specifically is it about such activities that impact testosterone and estrogen?"; the resounding theme is that when our nervous system is activated in particular ways, it drives our endocrine system and vascular system to activate or repress certain hormone networks in predictable ways. I also discuss peer-reviewed studies and protocols addressing (at a mechanistic level) how light, cold and heat, and respiration (breathing) can positively or negatively impact testosterone and estrogen. We discuss specific supplements and compounds that peer-reviewed studies illustrate can adjust testosterone and estrogen levels by changing their binding to other proteins, raising them directly, or changing other hormones released from the brain and pituitary. I discuss optimization in the normal reference ranges for these hormones, and I discuss pheromones, apnea, menstrual cycles, menopause and andropause.
