The Claim
Elevated cortisol levels reduce the secretion of luteinizing hormone by the pituitary gland, leading to decreased testosterone production in the testes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
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 cause the pituitary gland to release less luteinizing hormone, which results in lower testosterone production by the testes.
See the scientific wording
Elevated cortisol levels reduce the pituitary gland’s secretion of luteinizing hormone (LH), which is required to stimulate testosterone production in the testes.
High cortisol levels block the brain's signal to the pituitary gland to release luteinizing hormone, which stops the testes from making testosterone.
What the research says
1 studyStudy: Cortisol-induced suppression of plasma testosterone in normal adult males.
When stress hormone cortisol goes up, it messes up the body’s nighttime testosterone spike — which only happens when the pituitary gland releases LH. So higher cortisol likely means less LH, leading to less testosterone.
