Low testosterone, medically known as hypogonadism or Androgen Deficiency in the Ageing Male (ADAM), happens when the body doesn’t produce enough testosterone to support healthy physical, sexual, and emotional function. Testosterone plays an essential role in male development, sexual health, bone and muscle strength, energy levels, and overall well-being, so a significant drop can affect daily life in many ways.
Research suggests that about 26% of men in Singapore have testosterone levels that fall below the normal range, which may lead to testosterone deficiency syndrome (TDS) and a range of symptoms that men often overlook or attribute to ageing. At Elyon Clinic, we provide discreet, patient-focused men’s health care in Singapore, offering evidence-based support for hormone concerns, sexual health issues, and related conditions.
If you exhibit signs of low testosterone, such as those linked to TDS, it’s important to consult a doctor for evaluation and, if necessary, develop a treatment plan.
Testosterone typically peaks in early adulthood, then declines gradually each year. While the rate varies between individuals, research suggests that testosterone drops by about 1% each year after age 30, with a sharper decline in some men depending on health, lifestyle, and medical conditions.

Low testosterone isn’t diagnosed by age alone. Doctors assess symptoms, blood tests, and contributing factors before confirming testosterone deficiency.
Low testosterone can develop for several reasons. Common causes include:
Lifestyle Factors: Daily habits influence hormone balance. Lower testosterone may be associated with excessive alcohol consumption, smoking, high stress, lack of sleep, sedentary activity, and poor diet.
Testosterone Deficiency Syndrome (TDS) arises when a man’s body doesn’t produce sufficient testosterone. While it can occur at any age, it’s more prevalent in older men. Men with low testosterone levels may experience:
Male hormone deficiency significantly impacts men’s health, and many seek treatment to address these symptoms, especially when planning to start a family.
Men may have a higher risk of testosterone deficiency if they have:
Evaluating testosterone deficiency involves several structured steps to ensure accuracy and personalised care.
Your doctor reviews your symptoms, medical history, lifestyle habits, and any factors that may influence testosterone levels.
This includes an assessment of pubic hair distribution, muscle mass, testicular size, and signs linked to hormonal imbalance.
A morning blood test is usually recommended because testosterone is highest earlier in the day. The test typically takes 5–10 minutes.
If initial results show abnormalities, further tests may include hormone panels, semen analysis, pituitary imaging, genetic studies, and/or testicular ultrasound or biopsy.
Your doctor will discuss the results and recommend suitable treatment options based on your symptoms, age, and overall health.
The primary treatment for clinically confirmed testosterone deficiency is Testosterone Replacement Therapy (TRT). TRT restores testosterone to a healthy range and may help improve energy, libido, mood, and physical performance.
Most men notice improvements in symptoms within four to six weeks, although changes in muscle mass or physical strength may take three to six months.
TRT can provide meaningful improvements for men diagnosed with testosterone deficiency, addressing both physical and psychological effects:
For the most accurate measurement of your testosterone levels, the blood test must be taken in the morning, specifically between 8 AM and 11 AM.
Testosterone levels naturally fluctuate throughout the day, peaking in the early morning for men. Testing outside this window, especially in the afternoon or evening, will likely yield a lower (and potentially misleadingly low) result, as levels can drop by up to 30% later in the day.
At Elyon Clinic, we strictly follow this protocol to ensure that the initial measurement of your Total Testosterone is at its highest potential point, giving us the most reliable baseline to diagnose a clinically significant deficiency. If your morning results are low, further confirmatory tests may be required.
Total Testosterone (TT) – Measures the total amount of testosterone circulating in your bloodstream. However, most of this testosterone is bound to proteins (primarily Sex Hormone-Binding Globulin, or SHBG), making it biologically inactive. While it provides a good overall picture, a high TT level can sometimes be misleading if the binding proteins are also high.
Free Testosterone (FT) – Measures the tiny fraction of testosterone that is unbound to proteins. This “free” fraction is the biologically active hormone that is readily available to be used by your body’s tissues (such as muscles, brain, and sexual organs).
Yes, testing for both Total Testosterone and Free Testosterone is essential for a comprehensive and accurate diagnosis of male hormone deficiency at Elyon Clinic. We test both because a patient can have a Total Testosterone level that appears normal, but if their SHBG is high, their Free Testosterone may be dangerously low, leading to all the classic symptoms of deficiency. By checking both, our doctor gets a complete picture of how much testosterone your body is producing and, more importantly, how much is actually available for use.
In Singapore, clinical guidelines generally define a deficient (low) testosterone level based on the measurement of Total Testosterone in the blood. While laboratory reference ranges can vary slightly, a level is typically considered deficient or low if the Total Testosterone (TT) is below 8 nmol/L on a morning blood test.
For most cases of testing and treatment for male hormone deficiency at a private clinic, the costs are generally not covered by Singapore’s national savings scheme or standard private insurance plans.
Patients at Elyon Clinic should anticipate paying for the consultation, blood tests, and medication as out-of-pocket expenses. We recommend contacting your insurance provider directly for clarification on your specific policy benefits.
The time it takes to see results from TRT is gradual and depends on the specific symptom being treated. At Elyon Clinic, we advise patients that consistency is key, and not all benefits appear at once.
Our doctor will monitor your progress every few weeks initially, adjusting the dosage and type of therapy (e.g., gel vs injection) to help you achieve your desired results as efficiently as possible.
Yes, TRT can significantly and negatively affect a man’s fertility and sperm count. This is a critical discussion point at Elyon Clinic for all younger men considering TRT.
When testosterone is administered externally via TRT, the body’s natural hormone production system receives a signal to shut down its own production of hormones that drive sperm creation (Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). This can lead to a drastic reduction in sperm count and quality, potentially resulting in temporary infertility.
For men who are currently planning to have children or may want to in the future, TRT is usually contraindicated until family planning is complete.
The total expected cost of TRT in a private clinic setting can vary widely, typically ranging from S$100 to S$600 per month in the first year, depending on the treatment method, and stabilising after the initial phase. This cost is broken down into three main components:
The highest costs are usually in the first 6-12 months due to frequent testing and dosage adjustments, which then drop significantly once a stable maintenance dose is found.
After your blood sample is taken, you can generally expect the test results to be available and reviewed by your doctor within 3 to 5 working days.
No, you generally do not need to fast before taking the testosterone blood test at Elyon Clinic.
While TRT is generally safe when medically supervised, our doctors ensure patients are aware of the common side effects, which can often be managed through dosage adjustment and regular monitoring:
If a diagnosed, clinically significant low testosterone level is left untreated, the patient risks the worsening of physical, sexual, and mental health symptoms, potentially leading to long-term health complications.
At Elyon Clinic, we find that untreated low testosterone can lead to:
Treatment with TRT can reverse or halt the progression of these symptoms, significantly improving the patient’s quality of life and overall health profile.
Whether a male hormone deficiency can be fixed by itself depends entirely on the underlying cause of the low testosterone, which is categorised as either primary or secondary hypogonadism.
At Elyon Clinic, a thorough diagnostic process helps us determine the cause, guiding us to either recommend reversible lifestyle treatments or permanent replacement therapy.
