Study of 2,264 Finns Links Coffee to Higher Male Testosterone and Muscle Mass

Summary
Men in a Finnish study who drank more coffee showed higher total and bioavailable testosterone, along with lower total and visceral fat and more skeletal muscle.
Researchers at the University of Oulu analyzed 2,264 46-year-olds and said the pattern held even after accounting for body size and lifestyle factors.
The same men also had lower free testosterone and a lower free androgen index, alongside higher SHBG, pointing to a more mixed hormone profile than the headline result suggests.
Both men and women showed lower levels of amino acids tied to insulin resistance and type 2 diabetes, but the cross-sectional study could only show association, not that coffee caused the changes.
