One testicle bigger than the other: what is normal
Most men have one testicle bigger than the other or hanging lower. Usually this is completely normal, but a new difference in size can be a sign to get checked.
In short: It is normal for testicles to differ slightly in size, and for one, usually the left, to hang lower. A new or growing difference, a lump, heaviness or pain may be caused by a hydrocele, varicocele, epididymitis, a cyst, injury or, less commonly, testicular cancer. Regular self-checks help you notice changes early.
What is normal
- The right testicle is often slightly larger
- The left often hangs a little lower
- Small differences have usually been there since puberty
- Both should feel smooth, firm and similar in texture
Causes of a change in size
Hydrocele
Fluid around a testicle makes one side look swollen. Usually painless. See hydrocele in men.
Varicocele
Swollen veins, usually on the left, that feel like a bag of worms. See varicocele natural treatment.
Epididymitis
Inflammation of the tube behind the testicle, causing pain and swelling. Read epididymitis causes and recovery.
Cysts
Small, smooth lumps above or behind the testicle, usually harmless.
Injury
Bruising and swelling after a knock.
Testicular cancer
Most common in men aged 15 to 49. Often a painless lump or hardness, or a change in size or weight. Early detection makes a big difference.
Torsion
Sudden, severe pain with swelling is an emergency.
How to check your testicles
Once a month, after a warm shower:
- Hold each testicle between thumb and fingers and roll gently
- Feel for lumps, hard areas or changes in size
- Find the epididymis at the back so you know it is normal

When to see someone
See an appropriately registered medical professional if you notice:
- A new lump or hardness
- A testicle getting bigger or smaller
- Heaviness, aching or pain
- Sudden severe pain, which needs emergency care
