You were told your testosterone is "normal" so why do you still feel exhausted, weak, and off? The number on your lab report was never built for you, and your own genetics may be the reason it doesn't match how you feel.
In this solo episode, Dr. Gabrielle Lyon discusses:
- Why the standard 300–1000 ng/dL range ignores your age, comorbidities, and genetics, and why two men with identical labs can feel completely different
- How CAG repeats determine whether your body "catches" the testosterone you produce, meaning you might need 400 to feel great while someone else needs 800
- Why the 80-year-old fear that testosterone fuels prostate cancer is built on a single flawed 1941 study, and what the androgen saturation model proves instead
- How everyday endocrine disruptors BPA in receipts, phthalates in personal care, atrazine in tap water quietly lower your testosterone even when you eat clean and train hard
- The correct AUA testing protocol your doctor may be skipping: two early-morning, fasted measurements plus actual symptoms, not one afternoon blood draw
Understanding how your own body uses testosterone lets you walk into your doctor's office armed with facts instead of frustration and stop being told you're "fine" when you don't feel it.
