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.
Low Testosterone & Male Hormone Imbalance: What Every Man Should Know Are you feeling constantly tired, gaining belly fat, or noticing changes in your mood and sex drive? These aren’t just signs of “getting older.” They could be symptoms of low testosterone or a broader male hormone imbalance. Why Male Hormones Matter Hormones act as chemical messengers, controlling everything from energy and mood to muscle strength, weight, and sexual health. Think of them like instruments in a band: when they play in harmony, everything feels right. But when one is out of balance, the entire performance suffers. The key male...
The relationship between testosterone therapy and cardiovascular risk in men is one of the most debated topics in men's health. Headlines have warned of increased heart attack risk, yet the research tells a more nuanced story. Age, pre-existing cardiovascular disease, oestrogen levels, dosage, and delivery method all appear to play significant roles. This article examines the key findings from a major insurance-data study, explores the clinical questions it raises, and explains what men and their doctors should consider before starting or continuing testosterone therapy.
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.
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.
