Male sexual behavior influences the rates of cervical dysplasia and invasive cervical cancer, as well as male human papillomavirus
(HPV) infection and disease. Unfortunately, little is known ...regarding male HPV type distribution by age and across countries.
In samples combined from the coronal sulcus, glans penis, shaft, and scrotum of 1,160 men from Brazil, Mexico, and the United
States, overall HPV prevalence was 65.2%, with 12.0% oncogenic types only, 20.7% nononcogenic types only, 17.8% both oncogenic
and nononcogenic, and 14.7% unclassified infections. Multiple HPV types were detected in 25.7% of study participants. HPV
prevalence was higher in Brazil (72.3%) than in the United States (61.3%) and Mexico (61.9%). HPV16 (6.5%), HPV51 (5.3%),
and HPV59 (5.3%) were the most commonly detected oncogenic infections, and HPV84 (7.7%), HPV62 (7.3%), and HPV6 (6.6%) were
the most commonly detected nononcogenic infections. Overall HPV prevalence was not associated with age. However, significant
associations with age were observed when specific categories of HPV, nononcogenic, and unclassified HPV infections were considered.
Studies of HPV type distribution among a broad age range of men from multiple countries is needed to fill the information
gap internationally with respect to our knowledge of HPV infection in men. (Cancer Epidemiol Biomarkers Prev 2008;17(8):2036–43)
