What Is Andropause?
Unlike menopause — which involves a rapid hormonal shift over a relatively short period — andropause (male hormone decline, or late-onset hypogonadism) occurs gradually across decades. Testosterone levels decline approximately 1–2% per year beginning in the mid-30s, with some men experiencing clinically significant decline by their 40s or 50s. Yet andropause remains dramatically underdiagnosed and undertreated in conventional practice.
The Symptom Spectrum
The symptoms of andropause are often attributed to “normal aging” — a disservice to patients who are genuinely suffering from correctable hormonal decline. Common symptoms include: persistent fatigue and low motivation, decreased libido and erectile dysfunction, loss of muscle mass despite exercise, increased visceral body fat, mood changes (irritability, depression, anxiety), brain fog and poor concentration, poor sleep quality, and decreased bone density.
Contributing Factors Beyond Age
While age is the primary driver, multiple lifestyle and environmental factors accelerate testosterone decline: obesity (aromatase in adipose tissue converts testosterone to estrogen), chronic stress (cortisol suppresses testosterone production), alcohol excess, poor sleep, sedentary behavior, exposure to endocrine-disrupting chemicals (BPA, phthalates), and nutritional deficiencies. Addressing these factors is foundational regardless of whether TRT is initiated.
Diagnostic Approach
Diagnosis requires both symptom assessment and lab confirmation. Use a validated symptom questionnaire (ADAM — Androgen Deficiency in Aging Males, or AMS — Aging Male Symptoms scale) alongside comprehensive labs: morning total testosterone (two separate measures below 300 ng/dL confirm hypogonadism per Endocrine Society guidelines), free testosterone, SHBG, LH, FSH, estradiol, PSA, and CBC.
Conservative Management Before TRT
Before initiating TRT, address modifiable factors. Weight loss in obese men can raise testosterone by 100–200 ng/dL. Resistance training acutely and chronically elevates testosterone. Optimizing sleep (7–9 hours), reducing alcohol, correcting nutritional deficiencies (zinc, vitamin D, magnesium), and managing stress all meaningfully improve testosterone levels. For men near the threshold with modifiable risk factors, a 3-month lifestyle intervention trial is clinically appropriate.
When to Initiate TRT
TRT is indicated when: testosterone is consistently low (below 300 ng/dL on two morning samples), symptoms are present and impacting quality of life, conservative measures have been tried or are insufficient, and the patient has been counseled on benefits, risks, and fertility implications. The decision is individualized — a man at 280 ng/dL with severe symptoms and poor quality of life deserves treatment consideration even if he’s “technically” within some lab ranges.
