art of the study, nine had infections that lasted a year or more. Additionally, the researchers found that eight of these infections lasted two years or more, and two lasted four years or more, the researchers found.
In those who developed infections during the study, the team found that infections in men older than 45 all lasted one year or more. By contrast, just half the infections among men 31 to 44 years persisted for one year or longer. And none of the infections detected among men 18 to 31 years lasted for a year, according to the researchers.
“Our results show that some oral HPV16 infections persist in men for four years or more and that persistence seemed to increase with age,” Pierce Campbell said.
She also noted that genital HPV infections usually clear up in two years or less. This study’s findings suggest that oral infections may be more persistent than genital HPV.
