Prevalence Of HPV Infection In Heterosexual Men
The presence of HPV DNA in the anal area in heterosexual men may be explained by digital transmission either from a sex partner or by inoculation.
Men in Asia and the Pacific Islands have the lowest risk of anal HPV infection. This is consistent with the low prevalence of genital HPV seen in Korea and China.
It is a high prevalence but it is also a conservative number. Other studies have documented the prevalence of HPV in the United States as high as 60% and prevalence rates of close to 80% in other countries (Brazil).
The high prevalence HPV close to the anus suggest that the anal canal and/or perianal skin acts as a reservoir for HPV DNA in heterosexual men, and that this area may also serve as a site which can infect women. The presence of anal HPV infection in heterosexual men may also explain why these anatomic sites which are clearly not covered by condoms may account for the lack of reduction of HPV prevalence amongst those who consistently use condoms.
The prevalence is almost 8%.
The prevalence of any tested HPV type was 19% on the penis, 13% on the scrotum, 8% in the anal/rectal and 21% at any site.
50% of all HPV infections are caused by low-risk non-oncogenic strains.
A study conducted in the United States that reviewed the presence of 37 different HPV types documented a 30% prevalence of HPV infections in heterosexual men who had an HPV infections.
