Most bumps on the scrotum are completely harmless. The scrotal skin is packed with hair follicles, oil glands, and sweat glands, making it one of the most bump-prone areas on the body. What looks like a pimple is usually a normal anatomical feature or a minor irritation, not a sign of disease. That said, some scrotal bumps do need attention, so knowing what to look for matters.
Fordyce Spots: The Most Common Cause
The most likely explanation for small, painless bumps on the scrotum is Fordyce spots. These are oil glands sitting close to the skin’s surface without a hair follicle attached to them. They look white, yellowish, pale red, or skin-colored and measure 1 to 3 millimeters across, roughly the size of a sesame seed or smaller. They can show up as a few scattered dots or in clusters of 50 or more.
Fordyce spots are not an infection, not sexually transmitted, and not a sign of poor hygiene. They’re a normal variation in skin anatomy that most adult men have to some degree. They don’t itch, hurt, or change over time. No treatment is needed, and trying to squeeze or pop them will only cause irritation or infection in an area you really don’t want either of those things.
Folliculitis: Infected Hair Follicles
If the bumps are red, tender, or filled with pus, you’re more likely dealing with folliculitis. This happens when hair follicles become inflamed, usually from a bacterial infection (most often staph bacteria). The scrotum is covered in hair follicles, and the warm, moist environment makes it a prime spot for this kind of irritation.
Folliculitis on the scrotum typically looks like small clusters of pimples around individual hairs. You might notice itching, burning, or tenderness. Some bumps fill with pus, break open, and crust over. Common triggers include friction from tight underwear, excessive sweating, shaving or trimming, and not showering after exercise. Mild cases usually clear up on their own within a week or two with basic hygiene changes.
Angiokeratomas: Small Blood Vessel Bumps
If you’re noticing dark red, purple, or bluish bumps that feel firm and don’t hurt, these are likely angiokeratomas. These are small collections of dilated blood vessels just beneath the skin surface. They’re more common in men over 40 and tend to increase with age, though younger men can get them too.
Angiokeratomas are benign. They don’t spread, and they’re not contagious. The main concern is that they can occasionally bleed if scratched or irritated, since they’re essentially tiny tangles of blood vessels. They don’t require treatment unless bleeding becomes a recurring problem.
Bumps That Could Signal an STI
Some scrotal bumps are caused by sexually transmitted infections, and a few features help distinguish them from harmless causes.
Molluscum contagiosum produces small, raised bumps that are white, pink, or skin-colored with a firm texture and a distinctive dimple or dip in the center. They spread through skin-to-skin contact and can appear on the scrotum, inner thighs, or lower abdomen. They’re painless and eventually resolve on their own, though this can take months.
Genital warts from HPV tend to look different from typical pimples. They’re usually flat or slightly raised growths with an irregular, sometimes cauliflower-like texture. They can appear singly or in clusters on the scrotum, shaft, or surrounding skin.
Genital herpes follows a recognizable pattern. It often starts with tingling or shooting pain in the area, followed by small blisters that rupture into painful open sores, then scab over and heal. A herpes outbreak is rarely subtle. The sores are typically painful, and the first episode is usually the most severe.
How To Care for Scrotal Bumps at Home
For the majority of cases, which are folliculitis or other minor irritations, a few simple changes help:
- Shower daily, especially after sweating. Use a gentle soap and a clean washcloth around the affected area, then pat dry with a clean towel.
- Switch to cotton underwear. Synthetic fabrics trap moisture and heat, which encourages bacterial growth and friction.
- Don’t squeeze, pop, or pick at bumps. The scrotal skin is thin and has a rich blood supply. Popping a bump introduces bacteria and can turn a minor issue into a real infection.
- Avoid shaving the area if you’re prone to irritation. Trimming with a guard is less likely to cause ingrown hairs and folliculitis.
When Scrotal Bumps Need Medical Attention
Sudden pain in the scrotum is a medical emergency and needs immediate care, as some causes like testicular torsion can permanently damage the testicle within hours. Outside of emergencies, you should see a doctor if you notice a lump or mass that feels different from a surface-level skin bump, if bumps are growing or spreading, or if you develop sores that are painful, recurring, or accompanied by flu-like symptoms.
Any new mass in the scrotum, even if painless, is worth getting checked. Most turn out to be benign, but a physical exam can rule out the few things that aren’t.
