Human papillomavirus (HPV) is one of the most common infections in the world, affecting millions of men and women every year.

While it’s often discussed in relation to women’s health, men are also at risk — and many don’t realize it. Because HPV is usually symptomless, it’s been called a “silent virus,” one that can remain undetected for years before causing serious health problems.

What Exactly Is HPV?
HPV is a group of more than 200 related viruses. Some types cause harmless skin growths, while others can lead to cancers of the throat, anus, or genitals. The Centers for Disease Control and Prevention (CDC) estimates that almost every sexually active person will contract HPV at least once in their lifetime. Most infections clear naturally within a year or two, but persistent high-risk strains can lead to complications.
