Does body composition affect testosterone?
Yes. Excess adiposity raises aromatase activity and lowers testosterone; resistance training and lean-mass gain support endogenous testosterone. Body composition is a primary lever before and during hormone optimization.
Full answer
Adipose tissue is a major site of aromatase activity, converting testosterone to estradiol and contributing to lower total and free testosterone in men with excess body fat. Resistance training and lean-mass gain support endogenous testosterone production, SHBG balance, and insulin sensitivity. Sustained weight optimization is a primary lever before and during hormone optimization and frequently raises testosterone without pharmacology. The metabolic and hormone optimization pathways are designed to be additive on this foundation.
