Erythrocytosis, fertility impact, PSA screening, and the cardiovascular risk question — what testosterone replacement therapy safety actually involves and how it's monitored.

How Much Does TRT Cost? The Price of Testosterone Therapy in Poland [2026]

What does testosterone replacement therapy actually cost in Poland? We break the expense down into its components — diagnostics, consultations, medication (injections vs. gel), and monitoring — and explain why, for most men, TRT is in practice a private, out-of-pocket service rather than something covered by public health insurance.

TRT (Testosterone Replacement Therapy) — What Is It and Who Is It For?

TRT isn't a supplement for fatigue — it's pharmacological treatment for a confirmed testosterone deficiency, with a real but limited list of benefits and an equally real list of people who simply don't qualify for it.

Before a physician can qualify a patient for testosterone therapy, a far broader panel of tests is needed than testosterone level alone. The full list of blood tests, symptom questionnaires, and criteria that determine whether TRT is safe and appropriate.

How Often to Test Testosterone on TRT? Monitoring Schedule and Checkups

Starting testosterone therapy isn't the end of diagnostics — it's the start of a new, recurring rhythm of checkups.
