„If only I’d known how easy it is.“ –Testicular Self-Check

Testicular cancer is the most common cancer among young men between the ages of 15 and 40. 
At first, it might sound worrying – but: if detected early, it’s almost always curable. And the best part? Early detection starts with you. At home. In the shower. Just two minutes a month. Checking your testicles isn’t rocket science – it’s a simple step for your safety. And we’ll show you exactly how to do it – no panic, no embarrassment.

Why should I examine my testicles?

Because you are the first to notice any changes. Testicular cancer usually does not cause pain, especially in the early stages. A lump or hardening often goes unnoticed if you do not regularly check yourself. Early detection saves testicles—and lives.

When is the right time?

It is best to do this once a month, ideally after a warm shower or bath. This relaxes the tissue, allowing you to feel any hardened areas more easily.

How do you properly examine the testicles ?

Here are some simple instructions:

1. Stand in front of the mirror

This will allow you to see immediately if one of the testicles looks swollen or different.

2. Hold the testicle in both hands.

It is best to do this one at a time – always check one testicle at a time.

3. Gently roll the testicle between your thumb and fingers.

Look for lumps, hardening, or unusual swelling.

4. The epididymis (back/top) feels soft and string-like.

Don't be alarmed – this is normal. Only changes are significant.

5. Both testicles should be about the same size – but not identical.

Small differences are normal. Sudden changes are not.

What is normal —and what is not?

Normal:

  • Smooth, oval shape
  • No hard spots
  • Epididymis palpable as a soft structure
  • No pain when palpated

Unusual:

  • Lumps or hardening
  • Swelling or enlargement
  • Pulling sensation in the testicle or lower abdomen
  • Heaviness
  • Differences in size that are new

What if I feel something?

Don't Google it – get it checked out. Just come to our practice. Better once too often than once too late. The examination is quick, discreet, and completely straightforward. In most cases, these changes are harmless — such as cysts, epididymal cysts, or fluid accumulation (hydroceles). But only a quick check-up by a urologist can provide clarity.
