"Male menopause" is a phrase that gets thrown around a lot, usually to explain low mood, tiredness or a dip in libido in a man in his 40s or 50s. It sounds like a tidy explanation, borrowed from something most people already understand. The trouble is that it isn't an accurate one. This article looks at where the term comes from, what is actually happening to men's hormones with age, which symptoms genuinely relate to testosterone and which usually have other causes, and when it is worth arranging a blood test.
Why "male menopause" is a misleading name
The NHS describes "male menopause" as an unhelpful term, and for good reason. Menopause in women involves the ovaries stopping egg release over a relatively short period, with oestrogen levels falling sharply within a few years. There is no equivalent event in men: no organ switches off, and there is no sudden hormonal drop that mirrors what happens around menopause. Testosterone production in men does change with age, but gradually, over decades, not within a defined window of a few years.
The clinical term some doctors use instead is andropause, though even this is debated, since it implies a universal process that every man goes through in the same way. In reality, only a minority of men develop the kind of hormone changes that cause genuine symptoms worth treating. For most men, testosterone stays within a normal range well into older age, even as other, non-hormonal changes of ageing take hold.
Part of why the phrase has stuck is that it offers a single, tidy explanation for a cluster of changes that often arrive together in midlife: a less physically demanding routine, weight gain, disrupted sleep from work or family pressures, and the ordinary effects of getting older. Reaching for "male menopause" can feel like it names the problem, but treating it as a hormonal event when it usually isn't one can delay dealing with the things that are actually driving how someone feels.
What actually changes in men's hormones with age
From around the late 30s or 40s, average total testosterone in men falls by roughly 1 percent a year. That is a slow, steady slope rather than a cliff edge, and the rate varies a lot between individuals. Some men in their 60s have testosterone levels comparable to a man in his 30s; others see a more noticeable decline earlier, often linked to weight, general health or other medical conditions rather than age on its own.
This gradual decline is a normal part of ageing and, on its own, rarely causes problems. It only becomes clinically significant when testosterone falls low enough, consistently enough, to produce real symptoms. That specific picture has a name: late-onset hypogonadism, covered in more detail further down.
Symptoms that get blamed on it, and their other causes
A long list of complaints gets attributed to "male menopause": low energy, low mood, reduced interest in sex, difficulty concentrating, disturbed sleep, weight gain around the middle, and loss of muscle tone. Some of these can genuinely relate to low testosterone, which is why our guide to low testosterone symptoms and when to act is worth reading if several of them apply to you.
But every one of those symptoms also has far more common explanations. Depression and anxiety can cause fatigue, poor concentration and loss of libido on their own. Poor sleep, whether from insomnia, shift work or undiagnosed sleep apnoea, drives daytime tiredness and low mood regardless of hormone levels. Chronic stress raises cortisol, which can blunt motivation and sex drive. Carrying excess weight is linked to lower testosterone, but it also independently causes fatigue and reduced fitness. Heavy or regular alcohol use can lower testosterone and worsen sleep, mood and erectile function at the same time. Thyroid problems, diabetes and some medicines can produce an almost identical symptom picture.
Because the overlap is so large, the sensible first step with any of these symptoms is to have depression, sleep problems, stress, weight and alcohol intake assessed before assuming the cause is hormonal. Treating one of these underlying issues often resolves the symptoms without testosterone ever being the explanation. A GP can also review current medicines, since some, including certain blood pressure treatments and antidepressants, can themselves affect libido and energy.
Testing: when a testosterone blood test is worthwhile
A testosterone blood test is worth arranging if you have several of the symptoms above that have persisted for weeks rather than days, especially low libido, erectile difficulties, unexplained fatigue or loss of muscle mass, and other causes have not obviously explained them. Our article on getting a testosterone test in the UK covers how to arrange one through a GP or private service and how to interpret the result.
Testing is done first thing in the morning, when testosterone is at its daily peak, and a single low result is not diagnostic on its own. Levels can fluctuate with illness, poor sleep, recent heavy drinking or even the time of day the sample was taken, so a low reading is normally repeated on a separate morning before any diagnosis is made.
Late-onset hypogonadism and when TRT is considered
Late-onset hypogonadism is the clinical term for consistently low testosterone, confirmed on two separate morning blood tests, occurring alongside relevant symptoms. It affects a minority of men, and diagnosis depends on both the blood result and the symptom picture together: a low number without symptoms, or symptoms with a normal result, does not meet the definition.
For men who do meet the criteria, testosterone replacement therapy (TRT) may be considered to bring levels back into a healthy range and ease symptoms such as low libido, fatigue and reduced muscle mass. It is a prescription treatment, not something to self-diagnose towards, and it is not appropriate for men whose testosterone is within the normal range even if they have similar symptoms from another cause.
Lifestyle factors that move testosterone
Several everyday factors genuinely influence testosterone levels, and addressing them is worthwhile whether or not a blood test ever shows a low result. Carrying excess weight, particularly around the abdomen, is one of the strongest lifestyle links to lower testosterone, and gradual, sustainable weight loss can help. Poor or insufficient sleep disrupts the overnight hormone cycle that produces most of the day's testosterone, so improving sleep quality and duration matters in its own right. Regular alcohol use above recommended limits is linked to lower testosterone and can also affect liver function, which plays a role in hormone regulation. Resistance exercise and general physical activity are associated with healthier testosterone levels over time, alongside their broader benefits for mood, sleep and cardiovascular health.
None of these lifestyle changes amount to a certain fix for every symptom blamed on "male menopause", because, as covered above, many of those symptoms have nothing to do with testosterone at all. But they are sensible first steps that carry their own health benefits regardless of the outcome, and they are usually tried before, or alongside, any discussion of blood testing or treatment.
If you have made these changes, ruled out the more common non-hormonal causes, and symptoms such as low libido, fatigue or low mood persist, that is a reasonable point to speak to a GP or a UK-registered clinician about whether a testosterone blood test is worthwhile.
