The Claim
Elevated cortisol levels inhibit the hypothalamic release of gonadotropin-releasing hormone (GnRH), resulting in reduced signaling for testosterone production.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Higher levels of the stress hormone cortisol reduce the signal from the hypothalamus that triggers testosterone production.
See the scientific wording
Elevated cortisol levels inhibit the hypothalamic release of gonadotropin-releasing hormone (GnRH), reducing the signal to produce testosterone.
When cortisol levels rise, it directly reduces the amount of hormone released by the brain's GnRH neurons in each pulse and makes the pituitary gland less responsive to the GnRH signal, resulting in less testosterone production.
What the research says
1 studyWhen the body gets sick, it releases more stress hormone (cortisol), and this study shows that at the same time, the brain sends less signal to make testosterone. So high stress hormone levels seem to quiet down the system that makes testosterone.
