Andropause: The Male Hormonal Transition
Executive Summary
Breaking down the evidence for Late-Onset Hypogonadism and the reality of male hormonal decline.
Men don't 'fall off a cliff' hormonally, they 'slide down a hill.' Because it's slow, many men assume their loss of energy or mood shifts are just 'getting old.' The evidence shows that if the decline is significant enough to be clinical hypogonadism, medical support can restore metabolic health, muscle mass, and cognitive focus. It's not about 'youth,' it's about hormonal balance.
Clinical Brief
Andropause differs from menopause as it is not a sudden 'shutdown' but a progressive decline of 1-2% in total testosterone per year. Clinically, it is identified as Late-Onset Hypogonadism (LOH). Evidence-based diagnosis requires both low serum testosterone (typically <300 ng/dL) and symptoms like erectile dysfunction, fatigue, and loss of lean muscle mass.
Key Evidence Points
Testosterone levels decline gradually starting at age 30.
Low testosterone is associated with increased visceral fat and insulin resistance.
Diagnosis must rely on fasting morning blood tests, not symptom checklists alone.
Evidence supports TRT only when clinical deficiency is biochemically confirmed.
