Low testosterone signs, and the test that actually settles it.
Fatigue, low libido, muscle that will not build, mood that will not lift — the list of low-testosterone symptoms is long, vague, and shared with half of adult life. That is why a symptom list settles nothing and a ₩150,000 morning blood test at our Busan Seomyeon clinic settles most of it. This guide sorts the signs by how specific they are, explains how the test is done properly, and says plainly who should not be treated.

Which low testosterone signs actually mean something?
The signs most specific to low testosterone are reduced libido, fewer or weaker morning erections, and loss of muscle mass despite training; less specific are fatigue, low mood, poor concentration, increased body fat and reduced body hair, which have many other causes. At Urogyn Men's Clinic in Busan Seomyeon none of them is treated on symptoms alone: a ₩150,000 morning testosterone test, repeated once if low, is what establishes the diagnosis — and the full hormone panel at ₩500,000 is used when the picture is more complex.
Reduced sexual desire, fewer spontaneous or morning erections, and muscle that will not build or is being lost despite effort. Two or three together raise the probability considerably.
Real symptoms of low testosterone — and of poor sleep, stress, thyroid disease, depression, anaemia and ordinary overwork. On their own they do not point anywhere in particular.
Reduced body and facial hair, small or soft testes, and breast tissue enlargement are examined for on the day; they are uncommon but telling.
The men's health page covers the conditions; this page is about deciding whether to test, and what the test means.
Why does a symptom list settle nothing?
Because the list overlaps almost completely with being an adult under pressure. A man who sleeps six hours, drinks most evenings, trains inconsistently and is stressed at work will tick every box on a low-testosterone questionnaire and, more often than not, have a normal level. Conversely, a man with genuinely low testosterone may notice only that he has stopped wanting sex. Online questionnaires and symptom checklists were designed to prompt a test, not to replace one — and the clinics that treat on questionnaire scores are the ones our urologists in Busan see the consequences of: men on testosterone who never needed it, with side effects and suppressed fertility.
The test, done properly at our Busan clinic
- 1 Morning, ideally before 10am. Testosterone peaks in the early morning and falls through the day; an afternoon draw can read low in a normal man. The clinic schedules hormone tests for the morning.
- 2 Fasting is not required — but consistency is. A light breakfast is fine. Avoid a heavy meal, alcohol the night before, and intense exercise that morning, all of which shift the value.
- 3 Repeat once if low. A single low result is confirmed with a second morning draw on a different day before any diagnosis is made. Levels vary day to day, and treatment is not started on one number.
- 4 Add the panel when the picture warrants. The ₩500,000 full panel — LH, FSH, prolactin, SHBG, estradiol and thyroid alongside testosterone — locates the cause: testes, pituitary, or a binding-protein artefact.
Men who have a recent morning result from home should bring it — the what to bring guide explains why a prior value with its time of day can make the Busan draw the confirmatory one rather than the first.
Erectile Dysfunction in Busan
Low testosterone presents as low libido first and weaker erections second — the ED hub explains when a hormone result changes the ED plan and when it does not.
Read the ED hub →Reading the number
Total testosterone is reported in ng/dL or nmol/L on the laboratory report you receive, and laboratories quote a reference range that is wide because normal men vary widely. Broadly, a repeated morning total clearly below the lower limit of the range, in a man with specific symptoms, is low testosterone; a value in the lower part of the normal range with symptoms is a grey zone in which the free or bioavailable fraction and the wider panel matter; and a value in the middle or upper range makes low testosterone an unlikely explanation for the symptoms, however strongly they fit the list. The urologist at our Busan clinic reads the number against your age, your symptoms and your panel, and explains in English which of the three you are in. A number is not a verdict; a number plus a history is.
What else drops testosterone?
- Anabolic steroid use, current or past. Suppresses the body's own production, sometimes for a long time after stopping. The commonest cause of genuinely low testosterone in men under 40 at our clinic.
- Obesity and metabolic disease. Fat tissue converts testosterone to oestrogen; weight loss raises testosterone measurably — and gynecomastia is sometimes the visible sign.
- Sleep apnoea and chronic sleep loss. Suppress the overnight rise that morning levels depend on.
- Opioids, some antidepressants, glucocorticoids. Recognised suppressors. Bring the list.
- Pituitary causes. A raised prolactin, sometimes from a benign pituitary growth, lowers testosterone and is found on the full panel.
- Testicular causes. Prior injury, surgery, undescended testis, mumps orchitis, chemotherapy. The panel shows raised LH and FSH when the testes are the problem.
Several of these are treated by treating the cause, not by adding testosterone. That is the reason the panel exists.
Who should not be treated?
Three groups, said plainly at our Busan clinic before any injection. Men with a normal level, however tired: testosterone adds risk without benefit. Men who want children soon: testosterone replacement suppresses sperm production, sometimes for a long time after stopping, and the fertility screening page is the right starting point instead. And men with an unassessed prostate concern or a significantly raised PSA — ₩150,000 to check — until it has been evaluated, because testosterone is not started with an unknown prostate. The urologist declines to treat all three, and says why.
What does treatment in Busan look like if it is low?
First, the cause: steroid withdrawal, weight loss, sleep treatment, a medication change, a pituitary referral where the panel points there. Then, where a confirmed low level persists with specific symptoms and none of the exclusions apply, testosterone replacement — at Urogyn by injection, either Nebido at ₩500,000 per dose every ten to fourteen weeks or Jenasteron at ₩100,000 per dose every two to four weeks — with monitoring of testosterone level, blood count and PSA. The Nebido vs Jenasteron guide compares the two on interval, steadiness, travel and annual cost; the short version is that the long-acting injection suits men abroad and the short-acting one suits men who can attend easily.
What treatment cannot do
Three honest limits. Testosterone replacement does not fix fatigue that was caused by sleep, stress or depression — it fixes fatigue that was caused by low testosterone, which the test distinguishes. It does not build muscle by itself; it restores the capacity to build muscle with training. And it is not a short course: a man who starts replacement for a confirmed deficiency usually continues it, with monitoring, for years, because the underlying cause rarely reverses. Men who understand all three before the first dose are, in our urologists' experience, the ones who benefit. Every step is priced from the published list.
How it runs at our Busan Seomyeon clinic — and your next step
Message us with your travel dates, your symptoms — specifically libido, morning erections and muscle, then the rest — any prior testosterone result with its time of day, steroid or supplement history, medication, sleep, whether you plan children, and how often you could attend a clinic if treatment were needed. You will receive a reply in English confirming a morning slot for the ₩150,000 test or the ₩500,000 panel, and the urologist's honest provisional view. On the day, the same doctor draws, reviews, explains — and, only if the confirmed result and your circumstances warrant it, discusses treatment with its published price. For the detail, start with the men's health page; for every figure, the full price list.
- Can testosterone be tested from saliva or a home kit? Home kits vary in reliability and rarely include the panel that locates the cause. A morning venous blood draw read by a urologist is the standard, and the ₩150,000 test at Urogyn is that standard.
- I used steroids years ago and my level is low — will it recover? Often, given time and sometimes with medication that stimulates the body's own production rather than replacing it. The testosterone guide explains why replacement is not the first answer for a man who may recover, especially one who wants children.
