Mostly True 7/10
“Low muscle mass does not impair estrogen production.”
Available evidence supports the practical conclusion that low muscle mass is not known to meaningfully reduce systemic estrogen production. Ovaries and adipose tissue are much more important estrogen sources, and research chiefly shows low estrogen contributing to muscle loss. Direct studies have not established that muscle loss has absolutely no effect, so the categorical wording is stronger than the evidence.

“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.
