SOURCE-LINKED STUDY SUMMARY
Associations of dietary proteins with serum total testosterone and sex hormone-binding globulin concentrations in middle-aged men.
Abstract summarizedQuality not appraised
- What was studied
- A cross-sectional study examined associations between dietary protein sources, testosterone and sex hormone-binding globulin.
- Who / model studied
- The study included 2,546 Finnish men aged 42–60, using four-day food records and adjusted statistical models.
- Studied dose & schedule
- Dose and schedule have not yet been extracted for this summary.
- What the study found
- Compared with the lowest-intake group, the highest animal-protein group had total testosterone 1.2 nanomoles per litre lower; the highest plant-protein group had levels 1.1 higher. The hormone-binding protein followed the same directions. These were associations, not effects of assigned diets.
- Limitations & context
- Study limitations were not stated in the abstract. Methodological quality has not been appraised.
