Quick answer. “Andropause” or “male menopause” is a popular term for the gradual, age-related decline in testosterone; it is more accurately called late-onset hypogonadism. It is not a true equivalent of female menopause: testosterone falls slowly over decades (commonly described as a small, gradual decline from around age 30–40, though estimates vary) rather than dropping sharply, and many men never develop symptoms or truly low levels. The symptoms often blamed on it – low energy, reduced libido, mood changes, poor concentration – are non-specific and frequently caused by stress, depression, poor sleep, diabetes, thyroid problems or lifestyle. Many respond to lifestyle changes; testosterone therapy has a role only for men with confirmed low levels plus symptoms, prescribed and monitored by a doctor.

The phrase “male menopause” sells a lot of supplements and clinic visits – but the honest picture is more nuanced, and often more hopeful, than a hormone quick-fix.
What it is – and isn’t
“Male menopause” is the popular name for the age-related fall in testosterone; the accurate medical term is late-onset hypogonadism. The comparison with the female menopause is misleading. In women, the ovaries stop releasing eggs over a relatively short window, oestrogen falls sharply, and menstruation ends – a universal event with a clear before and after. In men there is no such switch. Testosterone drifts down slowly over decades, the change is very variable from man to man, and a large proportion of men reach old age without ever developing low levels or troublesome symptoms. Because the term implies a fixed, inevitable “change of life,” many clinicians dislike it: it can make a slow, treatable and sometimes unrelated set of problems sound like a single hormone crisis.
It helps to separate two things. The gentle, expected dip in testosterone that comes with getting older is normal and, on its own, usually causes no problems. True late-onset hypogonadism – a genuinely low testosterone level together with typical symptoms – is much less common, and is the only situation in which hormone treatment is even considered.
How testosterone changes with age
The decline is steady rather than sudden – often cited as about a proportion a year from around age 30–40, though estimates vary between studies and some report a smaller drop. This gradual change is a normal part of ageing and by itself rarely causes noticeable problems. What tips some men into symptoms is usually not age alone but a combination of factors, particularly weight gain, poor health and other illnesses, which is why lifestyle and general health matter so much in this condition.
Symptoms – and why they’re non-specific
The symptoms commonly attributed to andropause include reduced sex drive and fewer or weaker erections, low energy and tiredness, low mood or irritability, poor concentration and a sense of “brain fog,” reduced muscle strength with increased body fat (especially around the middle), disturbed sleep, and sometimes hot flushes or sweats. Some men notice reduced enjoyment of life or lower motivation.
The crucial point is that these symptoms are non-specific – on their own they point to many possible causes, most of which have nothing to do with testosterone. Stress, overwork, relationship difficulties, poor or broken sleep, depression and anxiety, excess alcohol, smoking, an underactive thyroid, erectile dysfunction from other causes, and long-term conditions such as diabetes can all produce exactly this picture. Assuming “it’s just my hormones” or “it’s just age” risks missing a treatable condition. This is why persistent symptoms deserve a proper assessment rather than a supplement bought online.
Causes and who is at risk
Several factors make low testosterone or its symptoms more likely. Ageing itself accounts for the slow background decline. Beyond that, being overweight or obese is one of the strongest and most reversible contributors – fat tissue changes how the body handles sex hormones, and central (belly) fat is particularly relevant. Type 2 diabetes and the metabolic syndrome are strongly linked to low testosterone. So are chronic illnesses affecting the heart, liver, kidneys or lungs, poorly controlled long-term conditions, obstructive sleep apnoea, and heavy alcohol use.
Some medicines can lower testosterone or blunt its effects, including long-term opioids, certain steroids, and treatments used for prostate cancer. Less commonly, low testosterone stems from a problem in the testicles themselves or in the pituitary gland in the brain that signals them – for example previous injury, infection, certain genetic conditions, or a pituitary tumour. These underlying causes are part of why a doctor looks for a reason rather than simply topping up the hormone.
How it is diagnosed
Diagnosis rests on symptoms plus a blood test that shows a genuinely low testosterone level – neither one alone is enough. Because testosterone naturally peaks in the morning and dips later in the day, the blood sample is usually taken in the morning, and because a single reading can be misleading, a low result is normally repeated on a separate day to confirm it before any label is applied. Levels can also be temporarily depressed by acute illness, so testing is best done when a man is otherwise well.
If low testosterone is confirmed, further tests help find the cause and exclude look-alike conditions. These may include hormones from the pituitary gland (to work out whether the problem is in the testicles or the brain’s signalling), together with checks for thyroid function, blood sugar or diabetes, blood count, and iron studies, plus a review of medicines, alcohol and sleep. In effect the doctor is asking two questions at once: is testosterone truly low, and if so, why – and is something else the real explanation for how the man feels. A specialist – an endocrinologist, urologist or men’s-health doctor – is often involved when the picture is unclear or treatment is being considered.
Treatment
The first step is almost always to address the reversible factors. Losing excess weight, exercising regularly (particularly resistance and strength training), improving sleep, cutting down alcohol, stopping smoking, and treating conditions such as diabetes, depression or sleep apnoea can each lift energy, mood and libido – and can raise testosterone in men whose levels were dragged down by these factors. Reviewing any medicines that may be contributing is part of this too. For many men these measures resolve much of the problem without any hormone treatment at all.
Testosterone replacement therapy is reserved for men with a confirmed low level and matching symptoms, prescribed and supervised by a doctor. It can genuinely help men who are truly deficient, improving libido, mood, energy and body composition. But guidelines are deliberately cautious: it is not an anti-ageing tonic, not a treatment for tiredness in men with normal levels, and not a shortcut to fitness. It suppresses sperm production and fertility, so it is generally avoided in men who still wish to father children. It is not suitable for men with untreated prostate or breast cancer, and is used with care where there is significant heart disease, a high red-blood-cell count, untreated severe sleep apnoea, or severe urinary symptoms from an enlarged prostate. Men on treatment need ongoing monitoring – typically of symptoms, testosterone levels, the blood count (which can rise), and prostate health including PSA and a prostate check. Be sceptical of “low-T” clinics and supplements that promise a hormone fix; testosterone is a medicine with real risks, not a wellness product.
Living with it and self-care
Whether or not hormone treatment is involved, the same healthy-living measures are the foundation. Aim for a healthy weight, since losing excess fat has one of the clearest effects on testosterone and on how you feel. Build in regular physical activity, combining aerobic exercise with strength training to protect muscle and mood. Protect your sleep – consistent hours and, where relevant, treatment of snoring or sleep apnoea. Keep alcohol within sensible limits, stop smoking, eat a balanced diet, and manage stress and low mood, seeking help for depression rather than dismissing it. These steps also protect the heart, blood-sugar control and overall health, which matter far more to long-term wellbeing than any single hormone reading.
When to see a doctor
See a GP or polyclinic doctor if you have persistent symptoms – ongoing low libido, erectile problems, unexplained fatigue, low mood or loss of drive – especially if they are affecting your daily life or relationship. The aim is to be assessed for low testosterone and for the many other causes that mimic it, rather than self-treating. Seek care sooner if symptoms are severe, if you have known diabetes or heart disease, or if you notice other changes such as loss of body hair, breast tenderness or shrinking testicles, which warrant proper evaluation. Singapore’s HealthHub and your family doctor are good starting points, with referral to an endocrinologist or urologist where needed.
