Could it be low testosterone?
Eight questions, about two minutes. This is not a diagnosis and not a medical intake — it is a structured way to see whether your pattern is worth testing, and which other explanations deserve ruling out first.
Quick answer: The common symptoms men associate with low testosterone — fatigue that sleep does not fix, lower sex drive, loss of strength, weight gain around the middle, low mood and poor concentration — are also caused by sleep apnea, thyroid disease, depression, alcohol, medications and iron deficiency. Symptoms alone cannot tell you which. Only a blood test, read by a clinician alongside your history, can.
The check
What else causes these symptoms
Before you conclude it is hormones, these are worth ruling out — a good clinician checks them in the same panel or the same conversation:
- Sleep apnea. It produces nearly the whole symptom list on its own, and it also lowers testosterone. See tired after eight hours of sleep.
- Thyroid disease. Fatigue, weight change, low mood, cold intolerance. A TSH is cheap and settles it.
- Depression and chronic stress. Overlapping symptoms, different treatment. See testosterone and mental health.
- Alcohol. Regular intake suppresses testosterone and wrecks sleep quality. See does alcohol lower testosterone.
- Iron, B12 and vitamin D. Ordinary deficiencies, ordinary fatigue.
- Medications. Opioids, some antidepressants, finasteride and steroids all affect hormones.

If you want the actual answer
Symptoms narrow the list. Bloodwork settles it. Our clinical intake is the next step when you are ready to test, and the testosterone therapy page explains what treatment looks like if a clinician determines it is appropriate.
