A new analysis of 13 studies looked at whether fenugreek, an herb often sold as a testosterone booster, actually raises testosterone in adult men. The studies compared oral fenugreek preparations with a placebo. The analysis found a small favorable association with total testosterone, but the evidence was very low certainty and based on only 6 of the 13 studies. For free testosterone, the results were imprecise and inconsistent, showing no clear effect.
The studies included adult men, but the analysis did not report the total number of participants or how long they took fenugreek. The researchers also noted a high risk of bias in some studies, meaning the results may not be reliable. No safety information was reported, so it is unclear if fenugreek caused any side effects.
The main limitation is the very low certainty of the evidence. The small effect on total testosterone could be due to chance or study flaws. The findings do not support the idea that fenugreek is a reliable way to boost testosterone.
For now, the evidence is too weak to recommend fenugreek for raising testosterone. Men considering it should talk to their doctor, especially since testosterone levels affect health in many ways. More rigorous studies are needed to know if fenugreek has any real benefit.
