Aging Male Syndrome, commonly called andropause, is not a simple equivalent of menopause in women. Some men, with age, experience symptoms such as decreased libido, worse erection, fatigue, loss of muscle mass, increase in fat tissue or low mood, but they are not always due to testosterone deficiency.
This article explains when it is worth testing testosterone, how to distinguish hormonal symptoms from stress, sleep apnea, obesity, diabetes, depression or the effects of drugs, and what an andrology consultation looks like. At Wyspa Medycyny Przyjaznej in Gdańsk, the patient can start with andrological consultation.

Decreased libido, chronic fatigue or worse erection after the age of 40?
Don't immediately assume it's "andropause". Similar symptoms may result from testosterone deficiency, but also from lack of sleep, obesity, diabetes, stress, depression, sleep apnea, thyroid disease or medications.

What is Aging Male Syndrome?
Aging Male Syndrome, abbreviated as AMS, is a term used to describe a set of symptoms that may appear in some men as they age. In medical practice, testosterone deficiency, hypogonadism or late-onset hypogonadism are more often referred to.
However, it is important not to diagnose AMS based solely on age. Fatigue, decreased libido, worsening erection, weight gain or worse mood can have many causes. Testosterone deficiency is one of them, but not the only one.
Therefore, reliable diagnostics include both symptoms and hormonal tests, as well as an assessment of overall health: sleep, body weight, metabolic diseases, medications, activity, stress and fertility.

Symptoms that may suggest testosterone deficiency
Symptoms of testosterone deficiency may be non-specific. The most diagnostically important complaints are those related to the sexual sphere, fertility and androgenic features, but the doctor assesses the patient's entire picture.
Symptoms worth discussing with an andrologist include:
- decreased libido,
- erectile dysfunction or weaker morning erections,
- difficulties in achieving a satisfactory erection,
- chronic fatigue and loss of motivation,
- loss of muscle mass or strength,
- increase in fat tissue, especially abdominal fat,
- deterioration of mood, irritability or decreased concentration,
- deterioration of sleep quality,
- decrease hair loss, hot flashes or excessive sweating,
- decreased fertility or abnormal semen analysis result,
- osteopenia, osteoporosis or low-energy fractures.
The more symptoms concern libido, erection, fertility, muscle mass and androgen characteristics, the more it is necessary to check the hormonal balance.
AMS-like symptoms - what should be ruled out?
One of the most common mistakes is explaining all symptoms with low testosterone. Meanwhile, decreased energy and libido may result from many other causes that require different treatment.
| Symptom | Possible cause other than testosterone | What should you discuss with your doctor? |
|---|---|---|
| fatigue and drowsiness | sleep apnea, sleep deficiency, anemia, thyroid, diabetes, depression | sleep, snoring, blood count, TSH, glucose/HbA1c |
| erectile dysfunction | vascular diseases, hypertension, diabetes, medications, stress, depression | pressure, lipids, glucose, medications, testosterone, lifestyle |
| decreased libido | stress, depression, medications, relationship problems, prolactin, thyroid | testosterone, prolactin, TSH, medications, mental health |
| weight gain | calorie surplus, insulin resistance, inactivity, sleep disorders | body weight, waist circumference, diet, activity, glucose, lipids |
| depressed mood | depression, chronic stress, burnout, alcohol, sleep disorders | mental assessment, sleep, stimulants, testosterone as one of the elements |
Why may testosterone decline with age?
In many men, testosterone levels gradually decrease with age. However, the pace and significance of this decline are very individual. Not every man over 40 or 50 is testosterone deficient and not everyone requires hormonal treatment.
Testosterone concentration is influenced, among others, by:
- age,
- obesity, especially abdominal obesity,
- type 2 diabetes and insulin resistance,
- sleep apnea,
- lack of physical activity,
- excessive alcohol consumption,
- chronic stress and sleep deficiency,
- certain medications,
- diseases of the testicles, pituitary gland or hypothalamus,
- chronic diseases and inflammation.
Testosterone levels may be reduced in obese men, but low levels alone do not always mean classic hypogonadism. In such a situation, it is particularly important to assess body weight, SHBG, metabolic diseases and the possibility of improving lifestyle.
How to properly test testosterone?
Testosterone has a circadian rhythm, so it is most often measured in the morning. The result should be interpreted together with the symptoms. If the result is low, the doctor will usually consider repeating the test and assessing additional hormones to determine the cause.
The following may be considered in diagnostics:
- total testosterone - basic examination, preferably in the morning,
- SHBG - sex hormone binding protein, important in the interpretation of free testosterone,
- albumin - helpful in calculating the free or bioavailable fraction,
- LH and FSH - help distinguish a testicular problem from a problem of the pituitary/hypothalamus,
- prolactin - especially in case of decreased libido, erectile dysfunction or very low testosterone,
- estradiol — in selected situations, e.g. obesity or gynecomastia,
- TSH — if the symptoms may be related to the thyroid gland,
- blood count, glucose/HbA1c, lipid profile, liver tests — when the doctor assesses general metabolic health.
The scope of tests should be tailored to the patient. Different tests will be needed in a man with erectile dysfunction, different in a patient with infertility, and still different in a person with obesity, diabetes or suspected pituitary disease.
Testosterone norms - why isn't a number enough?
Testosterone reference ranges vary between laboratories and testing methods. In practice, a value of approximately 300 ng/dL total testosterone is often discussed as a cut-off point to support the diagnosis of deficiency in a symptomatic patient, but it is not a stand-alone diagnosis.
Diagnosis requires a combination of symptoms with consistently low scores. Also important are: time of collection, SHBG, body weight, age, medications, chronic diseases, fertility and previous test results. In some patients, a "normal" result does not complete the diagnosis if the symptoms are significant and do not match the overall clinical picture.
Therefore, the testosterone result should not be interpreted solely by the online table. It is better to discuss it with a doctor who knows the patient's symptoms and context.
Should every man over 40 have their testosterone checked?
There is no need for routine testosterone testing in every man without symptoms. Diagnostics make the most sense when there are symptoms suggesting androgen deficiency or risk factors such as infertility, erectile dysfunction, osteoporosis, pituitary diseases, testicular diseases, use of specific medications or chronic metabolic diseases.
Testosterone testing should be discussed with your doctor if symptoms persist or affect your sex life, energy, mood, muscle mass or fertility. Age alone is not sufficient to diagnose AMS or to initiate treatment.
Treatment for AMS and low testosterone - what may it involve?
Treatment depends on the cause. For some patients, the most important will be treating obesity, improving sleep, reducing alcohol, increasing physical activity, treating diabetes or sleep apnea. Others will need hormonal diagnostics, treatment for testicular or pituitary disease, or therapy by a specialist.
Possible elements of the procedure include:
- weight reduction, especially abdominal obesity,
- strength training and aerobic activity adapted to health,
- sleep improvement and diagnosis of sleep apnea in snoring and daytime sleepiness,
- limiting alcohol and giving up smoking,
- treatment of diabetes, insulin resistance, hypertension and lipid disorders,
- review of drugs that may affect libido, erection or energy,
- treatment of erectile dysfunction, if any,
- diagnosis of infertility, if the patient is planning fatherhood,
- hormonal treatment only after medical qualification, if any indications.
In men planning a child, the issue of testosterone requires special caution. Exogenous testosterone may inhibit sperm production and impair fertility, so it should not be started without discussing reproductive plans.
Testosterone therapy – when does it require special caution?
Testosterone therapy is not an "energy treatment" for every man over 40. This is a hormonal treatment that requires indications, monitoring and discussion of risks. Before considering therapy, the doctor evaluates symptoms, test results, fertility, blood count, prostate disease, cardiovascular disease, sleep apnea and other contraindications.
During qualification, it is worth discussing:
- whether the diagnosis of testosterone deficiency is actually confirmed,
- whether the patient is planning fatherhood,
- what are the potential benefits and risks,
- how will the blood count, PSA and symptoms be monitored,
- what to do if side effects appear,
- whether sleep apnea, obesity or metabolic diseases need to be treated first.
The extent of possible hormone therapy in WMP should be confirmed prior to publication and should not be presented as an automatic option for every symptomatic patient.
Lifestyle - the foundation of a man's hormonal health
For many men, the greatest improvement is not brought by supplements, but by organizing the basics: sleep, body weight, activity, alcohol, stress and metabolic diseases. This especially applies to men with abdominal obesity, insulin resistance, type 2 diabetes or a sedentary lifestyle.
It is worth starting with activities that support general health:
- regular sleep and fixed hours of falling asleep,
- diagnosis of sleep apnea in the case of snoring, pauses in breathing and daytime sleepiness,
- regular strength training and aerobic activity,
- weight loss if you are overweight or obesity,
- a diet with adequate amounts of protein, vegetables, healthy fats and trace elements,
- limiting alcohol,
- quitting smoking,
- treating hypertension, diabetes and lipid disorders,
- reducing chronic stress and treating depression, if any.
Such actions can improve energy, erections, libido, weight and metabolic parameters - regardless of whether the patient is ultimately diagnosed with testosterone deficiency.
Supplements for AMS - do they make sense?
Supplements may make sense if they correct a confirmed deficiency, for example of vitamin D, zinc or other nutrients. However, they should not replace diagnostics. Preparations advertised as "testosterone boosters" often have limited evidence of effectiveness, and some potency or energy products may contain hidden active substances.
Before supplementation, it is worth determining:
- whether there is a deficiency of a given ingredient,
- whether the preparation does not interact with drugs,
- whether the patient does not have liver, kidney or heart diseases,
- whether the problem requires medical treatment instead of a supplement,
- whether the patient does not use several preparations with a similar composition at the same time.
The supplement can be an addition to the treatment plan, but should not be its foundation if sexual, hormonal or metabolic symptoms persist.
What does an andrology consultation look like?
The consultation begins with a conversation about symptoms: libido, erection, energy, mood, sleep, body weight, fertility, physical activity, medications and chronic diseases. Your doctor may ask about your morning erections, sex life, fatherhood plans, previous test results and supplements.
Depending on the situation, the consultation may include:
- interpretation of previous testosterone results,
- selection of hormonal tests,
- assessment of erectile dysfunction,
- assessment of fertility and indications for semen analysis,
- review of medications and supplements,
- discussion of lifestyle, sleep and metabolic diseases,
- determining whether further urological, endocrinological or internal medicine diagnosis is needed.
It is worth taking current test results, a list of medications, supplements and information whether the patient is planning to have children to the visit.

Frequently asked questions
Does andropause exist?
The term "andropause" is colloquial and can be misleading because men do not experience a sudden stop in hormonal function as in menopause. Some men may experience testosterone deficiency as they age, but this requires symptoms and confirmation by tests.
When should a man have his testosterone checked?
Testosterone should be discussed with your doctor in case of persistent loss of libido, erectile dysfunction, chronic fatigue, loss of muscle mass, infertility, low bone density or other symptoms suggesting androgen deficiency.
Does a testosterone result below normal mean a disease?
Not always. The result must be interpreted with the patient's symptoms, time of collection, SHBG, age, weight and diseases. It is often necessary to repeat the test in the morning and measure LH, FSH, prolactin or other parameters.
Does testosterone therapy improve energy and libido?
It may help some men with confirmed testosterone deficiency, but it is not a treatment for everyone. Before therapy, the diagnosis, cause, contraindications, fertility and monitoring plan must be established. Testosterone should not be used only "for fatigue".
Can testosterone worsen fertility?
Yes. Exogenous testosterone can inhibit sperm production and impair fertility. A man who is planning a child should definitely discuss this topic with an andrologist before starting any hormone therapy.
Do supplements help with AMS?
Supplements can only help if they address a specific deficiency or support a legitimate health goal. They do not replace hormonal diagnosis, treatment of erectile dysfunction, treatment of metabolic diseases or improvement of sleep, body weight and activity.
Which doctor should I see if I suspect Aging Male Syndrome?
It's best to start with an andrologist, urologist, or endocrinologist who specializes in men's hormonal health. The doctor will assess your symptoms, order appropriate tests and decide whether lifestyle changes, treatment of the underlying disease or hormone therapy are needed.
Decreased libido, worse erection or chronic fatigue?
Don't guess if it's testosterone. Andrological consultation allows you to select tests and determine the real cause of the symptoms.
Make an appointment for an andrology consultation →Summary
Aging Male Syndrome should not be diagnosed solely on the basis of age or well-being. Decreased libido, erectile dysfunction, chronic fatigue, fat gain and deteriorated mood can have many causes - hormonal, metabolic, psychological, drug and sleep-related.
The most important thing is correct diagnosis. Testosterone deficiency requires symptoms and confirmed, consistently low test results. Testosterone must be interpreted with SHBG, LH, FSH, prolactin, the patient's diseases, medications, lifestyle and fatherhood plans.
If you have symptoms suggesting low testosterone or want to discuss the results of hormonal tests, schedule an andrology consultation in Gdańsk .
