Kind: research · Impact: low

## In brief

- A study of more than 2,500 men linked higher animal protein intake, particularly from dairy, to lower testosterone levels.
- The reported association for plant protein is cut off in the available source excerpt.
- The source describes an association, not a proven cause-and-effect relationship.

## Why it matters

Diet is a modifiable factor, so an association between protein sources and testosterone could inform further research on male hormone health, though the available excerpt does not establish causation.
