One testicle feels bigger – should I be worried? If you’ve noticed this change and started to worry, you’re definitely not alone. Many men experience differences in testicle size at some point, and in most cases, a slight variation is completely normal. However, when the difference becomes more noticeable, such as one testicle feeling heavier, larger, or different in texture, it’s something that shouldn’t be ignored.
The most common cause behind this change is varicocele, where the veins inside the scrotum become enlarged, similar to varicose veins in the legs. A varicocele affects around 15% of all men and up to 40% of men dealing with fertility issues. It can cause visible swelling, a dull ache, or even gradual shrinkage of the affected testicle over time.
The good news is that surgery is no longer your only option. Dr. Gaurav Gangwani, a leading interventional radiologist in Mumbai, offers advanced non-surgical varicocele treatment, no scars, minimal downtime, and proven results for thousands of patients across India.
Let’s take a closer look at what might be causing this and what you can do about it.
Is It Normal for One Testicle to Be Bigger Than the Other?
Yes, in most cases, it’s completely normal for one testicle to be slightly bigger or hang lower than the other. The human body is rarely perfectly symmetrical, and the testicles are no exception. In fact, for many men, the left testicle naturally sits a bit lower due to differences in blood flow and anatomy.
A small difference in size or position usually isn’t something to worry about. Most of the time, it doesn’t cause pain, discomfort, or any impact on overall health. Many men notice this difference only by chance and live their entire lives without any related issues.
However, it’s important to pay attention to changes. If one testicle suddenly becomes larger, feels heavier, or develops a different texture, it shouldn’t be ignored. Gradual or noticeable changes can sometimes point to conditions like varicocele or other underlying issues that may need medical attention.
What Causes One Testicle to Be Bigger?
If you notice that one testicle looks or feels bigger than the other, you might feel a little worried. That is completely understandable. The truth is, this can happen for several reasons. Some are harmless, and others need a doctor’s help. The key is to know the difference so you can decide what to do next.
Here are the most common reasons explained simply.
Varicocele
This is a very common cause. It happens when the veins inside your scrotum do not drain blood well and become enlarged. You might feel a dull ache or a heavy feeling on one side. Some men say the texture feels soft and lumpy, like a small bag of worms. It usually shows up on the left side and may look more noticeable after you have been standing for a long time.
Hydrocele
A hydrocele is just a buildup of fluid around your testicle. It often looks like a smooth, painless swelling on one side. You might notice the size changes a little during the day. It is usually not serious, but if it gets very large, it can feel uncomfortable or heavy.
Infection (Epididymitis or Orchitis)
Infections tend to come on faster. Along with swelling, you will probably feel pain, tenderness, or warmth in the area. You might also run a fever or feel pain when you urinate. This type of problem usually needs medical treatment like antibiotics.
Testicular Torsion –
This is rare, but it is serious. It happens when the cord that brings blood to your testicle gets twisted. The pain is sudden and severe, and the swelling happens quickly. If you feel this kind of pain, do not wait. Go to the emergency room right away.
Testicular Tumor
Sometimes a change in size comes from a lump or growth. It may not hurt at all, which is why some men do not notice it at first. If you feel a hard spot or notice a lasting change in shape or size, you should get it checked by a doctor as soon as you can.
When Should You Consult with a Doctor?
Small changes in your body are quite usual, but there are certain signs that one should not overlook. You had better have it checked when you notice that one side of the testicles is larger than the other and the situation is new to you. Listening to your body may make you notice the issues at the initial stage and prevent complications.
- The sudden increase in size or swelling cannot pass unnoticed.
- When you experience pain or any discomfort on your scrotum, it is an indicator that something is wrong with your body.
- Dragging or feeling heavy all the time is something to check.
- Any lump or hardness to touch indicates you need to see a doctor.
- Wait not too long when the size continues to vary or gradually increases.
- Swelling, redness, warmth, and fever might be an infection.
- Any sudden sharp pain in your testicle should be treated urgently.
Treatment Options for Varicocele
If your doctor has told you that you have a varicocele, don’t panic – it can be treated. What works best for you depends on your symptoms, how much pain you feel, and whether it is causing any issues with your fertility. Some men do not need treatment right away, while others benefit from a medical procedure.
Here are the common treatment options explained simply.
Observation (Watch and Wait)
When you have a small varicocele and you do not experience pain or fertility issues, your physician might just advise you to have a follow-up of your varicocele. There is no immediate treatment.
Painkillers
In the event of discomfort, particularly following a lengthy standing period or exercise, your physician can recommend easy pain relief drugs. They do not cure the varicocele but will make you feel better.
Surgical Treatment (Varicocelectomy)
There are instances when surgery is carried out to tie off the affected veins. This assists in redirection of blood to normal veins. Nonetheless, this alternative includes incisions, surgical procedures, and an increased period of recovery.
Varicocele Embolization (Non-Surgical Treatment)
This is a modern and less invasive option. Some specialists, like Dr. Gangwani’s Vascular Clinic, offer this treatment.
Here is how it works:
A thin tube called a catheter is inserted through a small opening, usually in your groin or neck
- The doctor guides the tube to the affected vein using imaging
- Tiny coils or a special liquid are used to block the faulty vein
- This stops the abnormal blood flow and reduces the varicocele
- This option has a shorter recovery time compared to surgery because there are no large cuts or stitches.

Faqs
- How can I check at home if the size difference is normal?
You can gently feel both testicles during or after a warm shower when the skin is relaxed. If the difference has always been there and there’s no pain or lump, it’s usually normal. But if you notice a new change, it’s better to get it checked.
- Can a varicocele get worse if I ignore it?
Yes, in some cases it can slowly get worse over time. You may start feeling more heaviness or discomfort, and in some men, it can even affect fertility if not treated.
- Will I always feel pain if something is wrong?
Not always. Some conditions, like a small tumor or early varicocele, may not cause pain at all. That’s why any visible or lasting change should not be ignored.
- Is surgery the only way to treat varicocele?
No, surgery is not the only option today. Treatments like varicocele embolization are non-surgical and much less invasive, with quicker recovery and no major cuts.
- Where can I get a proper diagnosis and non-surgical treatment?
You can consult experts like Dr. Gaurav Gangwani, who specialize in advanced, non-surgical treatments for varicocele and related conditions, helping you get back to normal life faster.
