5. HPV in half of men

In the first study of its kind, JAMA has published a new finding. Nearly half—yes, HALF—of men were found to have genital HPV infections and roughly a quarter have at least one high-risk HPV subtype. While this finding is a bit mind-blowing, as well as horrifying, there is some good news. There’s an HPV vaccine that protects against nine different types of the virus, which the CDC recommends for all kids 11 to 12 years old. The study also found that just one in ten men had been vaccinated. Getting the vaccine is a good first step in prevention, however, more work may need to be done for awareness of the disease in men and the types of cancer associated with it.
