Does insulin resistance affect testosterone?
Yes. Insulin resistance lowers SHBG, alters androgen handling, and tracks with lower total testosterone in men. Improving insulin sensitivity often improves testosterone independent of pharmacology.
Full answer
Insulin resistance suppresses hepatic SHBG and is associated with lower total testosterone in men through multiple mechanisms — adipose aromatase, inflammatory signaling, and disrupted pituitary feedback. Improving insulin sensitivity through nutrition, training, sleep, weight optimization, and metabolic medications often raises testosterone independent of TRT. The opposite is also true: low testosterone worsens body composition and insulin handling, creating a feedback loop. The metabolic and hormone optimization pathways are designed to interrupt that loop.
