Most men with HPV will never see anything on their body at all. About one in three men over age 15 carry at least one type of genital HPV, yet the vast majority of infections produce zero visible signs. When HPV does cause something you can see, it typically shows up as genital warts, though the appearance varies widely depending on the HPV strain, the location, and how long the infection has been present.
What Genital Warts Look Like
Genital warts are the most recognizable sign of HPV in men. They appear as flat, raised, or stalk-like growths on the genital skin. Some are smooth and dome-shaped, while others develop the rough, bumpy “cauliflower” texture most people associate with warts. They’re usually flesh-colored or slightly darker than the surrounding skin, though they can appear grayish or whitish on mucosal tissue.
Warts can show up as a single bump or in clusters. They range from barely visible (a millimeter or two) to several centimeters when multiple warts merge together. They’re typically painless, though some men notice mild itching. Common locations include the shaft of the penis, the foreskin, the head of the penis, the scrotum, the groin folds, and the skin around or inside the anus.
These warts don’t appear right away after exposure. The incubation period is one to six months, so you may not notice anything until well after the sexual contact that transmitted the virus.
Conditions That Look Similar but Aren’t HPV
Several harmless conditions on the penis can be mistaken for warts, which is a common reason men search for this topic in the first place.
- Pearly penile papules are small, smooth, dome-shaped bumps that form a neat ring around the rim of the head of the penis. They’re uniform in size and spacing, which distinguishes them from warts. Warts tend to be more irregular, vary in size, and don’t follow that tidy circular pattern. Papules are completely normal and not caused by any infection.
- Fordyce spots are tiny white or yellowish dots on the shaft or foreskin. They’re visible oil glands, not growths, and they feel flat rather than raised.
- Molluscum contagiosum produces firm, round bumps with a small dimple in the center. This is caused by a different virus entirely and has a distinct “belly button” indentation that warts lack.
If you’re unsure what you’re looking at, a clinician can usually tell the difference with a visual exam.
Oral HPV: Often Invisible
HPV can also infect the mouth and throat. Most oral HPV infections cause no symptoms whatsoever. Less commonly, small warts or sores appear on the lips, inside the cheeks, or in the throat, but these are easy to miss.
The bigger concern with oral HPV is that certain high-risk strains can, over years, lead to oropharyngeal cancer. These cancers usually start as a tiny lump on the tonsils or at the base of the tongue, making them hard to spot in early stages. As they progress, signs include a persistent lump in the neck or cheek, or a white or red patch on the tonsils. A sore throat that won’t resolve, difficulty swallowing, or unexplained ear pain on one side can also develop.
When HPV Causes Something More Serious
The low-risk HPV strains that cause visible warts are not the same strains linked to cancer. About one in five men carry high-risk (oncogenic) HPV types, and these rarely produce any visible sign until they’ve progressed significantly. Penile cancer is rare, but nearly all cases occur on or near the head of the penis.
Early signs of penile cancer include a reddish rash, small crusty bumps, flat bluish-brown growths, persistent itching, or a wart-like growth on the glans or the skin immediately around it. As it progresses, an open sore that won’t heal, bleeding from a mass, or swelling at the tip of the penis can develop. Any of these changes that persist for more than two weeks warrants a medical evaluation.
Anal cancer from HPV follows a similar pattern. Early signs include persistent itching, bleeding during bowel movements, a lump near the anus, or changes in bowel habits. Men who have receptive anal sex are at higher risk.
Why Most Men Never Know They Have It
There is no approved HPV screening test for men. The HPV tests used in cervical cancer screening are specifically designed for that purpose and are not recommended for use in men of any age. This means most men only learn they have HPV if visible warts appear or, in rare cases, if an HPV-related cancer is diagnosed.
The good news is that the immune system handles most infections on its own. In a large cohort study tracking men over time, 66% cleared a new HPV infection within 12 months, and 90% cleared it within 24 months. Genital warts, when they do appear, can be treated and removed, but the underlying virus simply needs time to be suppressed by the immune system.
Because most HPV is invisible and there’s no male screening test, vaccination before exposure remains the most effective protection. For men already dealing with visible warts, the warts themselves are treatable and caused by low-risk strains that don’t lead to cancer.
