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

Andropause — often called male menopause — describes the gradual decline in testosterone and other key hormones that affects many men from their forties onwards. Unlike the relatively abrupt hormonal shift of female menopause, andropause develops slowly, making its symptoms easy to dismiss as normal ageing or stress. Yet the hormonal changes involved — including declining testosterone, rising oestrogen, cortisol dysregulation, and thyroid dysfunction — can significantly affect energy, mood, body composition, sexual health, and cognitive function. This article explains what andropause is, the key hormones involved, how to recognise its symptoms, and how comprehensive hormone testing can identify the specific imbalances driving your symptoms.

When it comes to topical testosterone therapy, more is not always better. Dr. Allison Smith of ZRT Laboratory explains the U-shaped curve phenomenon — where both too little and too much testosterone produce the same symptoms — and why starting at low doses and titrating carefully is essential. She also outlines the key markers to check when a man’s testosterone numbers look good on paper but his symptoms persist.

Explore why many men on topical testosterone replacement therapy may be unintentionally over-dosed due to outdated serum testing methods and misunderstood dosing principles. Learn how saliva and dried blood spot testing better reflect bioavailable testosterone delivered to tissues, why physiological dosing matters, and how excessive testosterone may suppress natural hormone production, reduce receptor sensitivity, and negatively affect long-term symptom management and hormonal balance.
