You’re probably here because something looks weird. Maybe it’s a lump you found in the shower, or perhaps you’re just spiraling on a late-night Google search trying to figure out if your anatomy is "standard issue." Honestly, most guys have no idea what they’re looking at. We spend a lot of time thinking about the "main event" upstairs, but the scrotum is basically the neglected basement of the male reproductive system. It’s a complex, sensitive, and often lumpy-looking area that causes a massive amount of unnecessary anxiety.
Let’s get one thing straight: if you are looking for pictures of mens testicles to diagnose yourself, you’re going to find a lot of terrifying medical outliers. You’ll see Stage 4 tumors or rare infections that look like props from a horror movie. That isn't helpful. Real-world anatomy is messy. It’s rarely symmetrical. One hangs lower—usually the left, though not always. The skin is wrinkled, darker than the rest of your body, and covered in hair follicles that can sometimes look like tiny white bumps (more on those later).
Why Comparison Photos Usually Fail You
The problem with searching for visual references online is the lack of context. A static image doesn't tell you if a lump is "squishy" like a bag of worms or hard like a pebble. It doesn't tell you if the redness is itchy or painful. Medical textbooks use idealized versions or extreme pathologies.
The scrotum is a thermoregulation suit. It’s supposed to move. If it’s cold, the cremaster muscle pulls everything tight to the body. If it’s hot, things loosen up. This means the way your testicles look at 9:00 AM might be completely different from how they look after a hot shower at 7:00 PM. This constant shifting makes self-diagnosis via photos almost impossible for the untrained eye.
The "Bag of Worms" and Other Common Oddities
You might see something that looks like a bunch of tangled veins just above the testicle. In the medical world, this is called a varicocele. It’s basically a varicose vein, but in your scrotum. It affects about 15% of men. While it can look alarming in a high-res photo—often described as a "bag of worms"—it’s usually harmless, though it can occasionally mess with fertility or cause a dull ache.
Then there are spermatoceles. These are cysts that form in the epididymis (the tube that sits behind the testicle). If you were to see a cross-section, it’s just a fluid-filled sac. On the outside, it just looks like a third, much smaller ball. It’s benign. But seeing a photo of one without knowing what it is? That’s a fast track to a panic attack.
Spotting the Real Red Flags
We need to talk about what actually matters. While aesthetic variations are normal, certain visual and tactile changes are non-negotiable reasons to see a urologist. Dr. Edward Schaeffer at Northwestern Medicine often emphasizes that "painless" lumps are actually the ones that need the most immediate attention.
- The Hard Lump: If you feel something that feels like a grain of rice or a small marble attached to the testicle itself, that’s the big one. Testicular cancer is highly treatable—95% survival rate if caught early—but it doesn't usually hurt.
- Sudden Swelling: If one side suddenly looks like a grapefruit and it hurts like hell, stop reading this and go to the ER. That could be testicular torsion (the cord twisting) or a severe infection like orchitis.
- Redness and Heat: This usually points toward an infection or an abscess.
Those Tiny White Bumps Aren't STIs
Every week, thousands of men freak out over Fordyce spots. These are small, painless, raised yellowish or white bumps on the scrotum or shaft. They are just enlarged sebaceous (oil) glands. They aren't contagious. They aren't an STI. They are just part of your skin’s architecture.
Another common visual "false alarm" is idiopathic scrotal calcinosis. These are hard, painless nodules that appear over time. They look like little white stones under the skin. They're literally just calcium deposits. While they look bizarre in photos, they aren't dangerous, though many men choose to have them removed for cosmetic reasons.
The Reality of Symmetry
Perfect symmetry is a myth. In most men, the left testicle sits lower than the right. Evolution likely did this so they don't bash into each other when you walk or run. If you see a photo where everything is perfectly aligned and smooth, it’s probably photoshopped or a medical illustration.
The skin itself, the scrotum, is naturally hyper-pigmented. It’s supposed to be darker. It’s also prone to things like folliculitis (inflamed hair follicles) and fungal infections (jock itch). A red, scaly rash in the folds isn't usually a "testicle" problem; it's a skin problem caused by moisture and friction.

How to Actually Perform a Check
Forget the photos for a second. Your hands are better diagnostic tools than your eyes. The best time to check is during or right after a warm shower when the scrotal skin is most relaxed.
- Isolate: Use both hands to find one testicle.
- Roll: Gently roll it between your thumb and fingers. It should feel like a smooth, firm hard-boiled egg (without the shell).
- Identify the Epididymis: You will feel a soft, ropey structure at the back. That’s normal. Don't mistake that for a tumor.
- Compare: Do the same for the other side. Note any differences in firmness or "new" lumps that weren't there last month.
When to Stop Looking at the Screen and Call a Doctor
If you have found a lump that is firm and fixed to the testicle, a photo won't save you. You need an ultrasound. It’s a quick, painless test that uses sound waves to see if a lump is solid (potentially cancer) or fluid-filled (usually a cyst).

Also, keep an eye on "heaviness." Sometimes the scrotum doesn't look different in a picture, but it feels like there’s a weight pulling on your groin. This can be a sign of a hydrocele—a buildup of fluid around the testicle. It’s common, especially as men age, but it still needs a professional look to rule out underlying issues.
Summary of Actionable Steps
- Perform a monthly self-exam: Consistency is key so you know what "normal" feels like for you.
- Ignore the "perfect" look: Veins, wrinkles, and slight asymmetry are the baseline, not the exception.
- Document changes: If you see a lesion or a sore that doesn't heal in two weeks, take a photo to show your doctor—don't just compare it to random ones online.
- Wear loose clothing: If you're dealing with redness or irritation, moisture is the enemy. Switch to cotton boxers and keep the area dry.
- Schedule a Urologist visit: If you find a hard, painless lump, get an appointment. It's likely nothing, but the peace of mind is worth the co-pay.
