The Claim
In men, having low muscle mass causes estrogen levels to become abnormally high.
The evidence does not support low muscle mass as a cause of abnormally high estrogen in men. Higher estradiol is more consistently associated with increased fat mass and aromatization, while studies often find weak, inconsistent, or no independent link between estradiol and muscle mass. The claim confuses low muscle with high body fat and overstates both causation and hormone abnormality.
