Your values are fine
Then the cause probably lies elsewhere. The doctor looks with you at sleep, stress, weight and medication.
In men, testosterone falls gradually over the years, but by no means every symptom is caused by it. Tap what you recognise.
Not everything is testosterone. Poor sleep, stress, being overweight, alcohol, certain medicines or an underactive thyroid can cause exactly the same symptoms. That is why the doctor looks at the whole picture.
Measure first, then decide. That way you avoid using something you don't need.
01You tell us which symptoms you have, for how long, and how things are with your health, your medication and any wish to have children.
02With a small shoulder prick you take a little blood yourself, preferably in the morning. We measure your testosterone, SHBG, LH, FSH and blood count, among others.
03A BIG-registered doctor puts your result next to your symptoms and discusses with you what it means.
04Sometimes that is treatment, often something else: better sleep, less alcohol, different training or further tests.
If you do not have a recent result, you start with the BlueTest. The check is no guarantee of treatment.
Broadly, there are three outcomes. Each one gets you further, even if testosterone turns out not to be the cause.
Then the cause probably lies elsewhere. The doctor looks with you at sleep, stress, weight and medication.
Then the doctor discusses whether treatment suits you, what it means for your fertility and which check-ups come with it.
For example your thyroid, iron or blood sugar. Then the doctor looks with you at what makes sense next.

No. Tiredness has many possible causes. A deficiency is diagnosed with symptoms and a blood test, and the doctor assesses them together.
Your testosterone fluctuates during the day and is usually highest in the morning. A morning measurement therefore gives the fairest picture.
For most men the BlueTest gives a good picture: we measure your testosterone and the values needed to interpret the result. If more is needed, the doctor will discuss it with you.
Then testosterone therapy is not on the table, and that is an answer too. The doctor looks with you at what else may be behind your symptoms, such as sleep, stress or weight.
Testosterone from outside the body suppresses sperm production. If you want children, treatment is usually not suitable. Always discuss it with the doctor.
During treatment your blood values are checked, including your testosterone and haematocrit, and your prostate where needed. The doctor discusses with you beforehand how and when.
For example with prostate or breast symptoms, or if the doctor wants to examine you. That cannot be done online; the doctor will then discuss with you how to arrange it.
Testosterone is prescription-only and is only prescribed with symptoms and a deficiency proven by a blood test, after assessment by a BIG-registered doctor (Dutch medical register). A treatment is therefore never guaranteed.
Testosterone therapy is not suitable with, among other things, (a history of) prostate or breast cancer or an active wish to have children, and it can reduce your fertility. During treatment your blood values are checked. If you use a product on the skin, avoid skin contact with others, especially children and pregnant women. Read the patient information leaflet before use; more information is available at apotheek.nl (in Dutch).
If you have chest pain, sudden shortness of breath or a painful, swollen leg, call 112 immediately. For side effects or doubts, contact our medical team.
Start the check whenever it suits you. You begin with a few questions and, if you have no recent result yet, the BlueTest.
