The Claim
Excessive muscle mass in men causes estrogen deficiency.
The evidence does not support the idea that excessive muscle mass in men causes estrogen deficiency. In men, low estrogen is usually linked to low testosterone, impaired aromatization, certain drugs, or endocrine disease—not to having a lot of muscle. Several credible sources point in the opposite direction or find no such causal relationship.
