Andropause (Male Menopause): Symptoms and Testing
Andropause (late-onset hypogonadism) describes the gradual fall in testosterone that begins in many men from their late 30s onward. Whether symptoms appear depends on the rate of decline and individual sensitivity. Morning testing of total and free testosterone, DHT and thyroid distinguishes andropause from other causes of the same symptoms.
This patient information is being clinically reviewed by our team. The factual content draws on UK guidance (NHS, NICE, British Association of Dermatologists, British Society for Sexual Medicine where cited).
What this might be
- Age-related decline. Roughly 1 percent per year fall after age 30 to 40; symptoms appear at variable thresholds.
- Obesity and metabolic syndrome. Adipose tissue converts testosterone to oestrogen, accelerating apparent decline.
- Sleep apnoea. Disrupts overnight testosterone production; worth assessing if symptoms persist.
- Medication and substance contributors. Opioids, glucocorticoids, alcohol and anabolic steroid use all suppress production.
Common features that suggest this
- Reduced energy and motivation
- Lower libido or erectile changes
- Mood changes or irritability
- Reduced muscle bulk despite training
- Increased abdominal fat
- Hot flushes (uncommon but reported)
Recommended tests
Same-day appointments at our Harley Street clinic, results clinician-reviewed.

Testing advice
Morning appointment (before 11am). Repeat testing on two separate days is best practice before considering treatment.
Common questions
When should I consider testosterone replacement?
Only after confirmed low levels on two morning samples plus consistent symptoms, and after a clinical discussion of risks and monitoring. Bloodwork is the foundation but not the whole decision.
Is private testing better than NHS?
For symptomatic men, private testing usually offers faster access, free and total testosterone in the same draw, and a doctor review with the result. NHS may require multiple visits to obtain similar information.
