Men get HPV through sexual contact, primarily vaginal, anal, or oral sex with someone who carries the virus. But penetrative sex isn’t the only route. HPV also spreads through close skin-to-skin touching during sexual activity, which means the virus can transmit even without intercourse. Most sexually active men will encounter HPV at some point in their lives, and most will never know it.
How HPV Spreads to Men
HPV lives in skin and mucous membrane cells, not in blood or semen. That distinction matters because it means the virus transfers when infected skin touches uninfected skin. Vaginal and anal sex are the most common transmission routes, but oral sex can deliver HPV to the mouth and throat, and genital skin-to-skin contact during foreplay or non-penetrative sex can spread it as well.
The person passing the virus often has no idea they carry it. HPV rarely causes visible symptoms, so a partner can look and feel completely healthy while shedding virus from their skin. There is no routine HPV test for men, and most infections clear on their own within one to two years without ever being detected. This silent nature is exactly why HPV is so widespread.
Where HPV Infects Men
The virus doesn’t land randomly. It targets specific areas where skin is thinner or more vulnerable to micro-abrasions during sex. In uncircumcised men, the area under the foreskin is a common site. In circumcised men, the penile shaft is more typically affected. The scrotum, perineum (the skin between the scrotum and anus), and perianal skin are also susceptible, even in men who haven’t had receptive anal sex.
The mouth and throat are another major infection site. About 10% of men carry oral HPV at any given time, compared to 3.6% of women. Oral HPV is transmitted primarily through oral sex, though other pathways may exist. Most oral infections clear without consequence, but a small fraction involve high-risk HPV strains that can lead to cancer years later.
Why Condoms Help but Don’t Fully Protect
Consistent condom use reduces HPV risk, but only when the condom covers the infected area. HPV can live on skin that a condom doesn’t reach: the base of the penis, the scrotum, the inner thighs, and the perianal region. So while condoms are worth using for this and many other reasons, they don’t eliminate HPV transmission the way they do for infections that travel in bodily fluids.
Circumcision and HPV Risk
Circumcision provides a measurable reduction in HPV acquisition. A randomized controlled trial in Kenya found that circumcised men were about 39% less likely to acquire a new penile HPV infection over two years compared to uncircumcised men. The foreskin creates a warm, moist environment where the virus can survive longer and where the skin is more prone to the tiny tears that let HPV enter cells. Removing it reduces, but doesn’t eliminate, that vulnerability.
What HPV Can Cause in Men
Most HPV infections in men cause nothing at all. The immune system clears the virus quietly. But some strains cause visible problems, and others carry serious long-term risk.
Low-risk HPV strains (types 6 and 11) cause genital warts, which can appear on the penis, scrotum, groin, thighs, or around the anus. These warts are not dangerous but can be uncomfortable and distressing. They sometimes appear in less expected locations too, including the mouth, nasal passages, and throat.
High-risk strains are the real concern. Each year in the United States, roughly 13,600 throat cancers in men are attributed to HPV, making it the most common HPV-related cancer in men by a wide margin. Anal cancer accounts for about 2,300 cases per year in men, and penile cancer adds another 900. These cancers typically develop years or even decades after the initial infection, which is why many men don’t connect the diagnosis to a virus they picked up long ago.
HPV Vaccination for Men
The HPV vaccine is recommended for all males through age 26 if they weren’t vaccinated earlier. The ideal time to start is around age 9 to 12, well before any sexual exposure. Boys who begin the series before their 15th birthday need only two doses, spaced 6 to 12 months apart. Those who start at 15 or older need three doses over six months.
Men between 27 and 45 who were never vaccinated can still get the vaccine after discussing it with a healthcare provider. The benefit decreases with age because most adults in that range have already been exposed to common HPV strains, but the vaccine can still protect against strains they haven’t encountered. For men with weakened immune systems, including those living with HIV, three doses are recommended regardless of the age they start.
The vaccine covers the HPV strains responsible for the vast majority of HPV-related cancers and genital warts. It is preventive, not therapeutic, so it works best before exposure occurs. But even men who have already had one HPV strain can benefit from protection against others they haven’t yet encountered.
