Protein sources linked to differing testosterone levels in men
A study of 2,546 men by researchers at the University of Eastern Finland links protein sources to testosterone levels. Men with the highest animal protein intake had lower total testosterone than those with the lowest intake, by an average of 1.2 nanomoles per litre. Men with the highest plant protein intake had levels 1.1 nanomoles per litre higher than the lowest-intake group. Higher dairy protein intake was linked to lower total testosterone and sex hormone-binding globulin. The study does not show that changing diets raises testosterone.
Key facts
- Researchers at the University of Eastern Finland conducted the study, as reported by Euronews.
- The study reports associations, not proof that changing protein intake alters testosterone.

Why it matters
The findings link diet composition to a hormone involved in male health, though they do not establish cause.
