Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — testosterone and male wellness

Testosterone has long been associated with aggression — but new research is revealing a far more nuanced picture. A study published in Nature Communications, involving ZRT Laboratory, found that a single dose of testosterone significantly increased young men’s preference for luxury, status-enhancing goods. Dr. Kate Placzek explores the neuroendocrine science behind this finding — and what it reveals about testosterone’s role in dopamine, reward and social behaviour.

An FDA-approved testosterone gel was shown to significantly increase cardiovascular risk in older men — but does this mean testosterone therapy is dangerous? ZRT Laboratory’s research suggests the real problem lies in how testosterone is measured. Venous serum testing dramatically underestimates tissue exposure to topical testosterone, leading to pharmacological overdosing that goes undetected. This article explains why the testing method matters as much as the dose.
