Risk Factors For HPV Infection In Heterosexual Men
The studies in female virgins document an association between non-penetrative sex, finger/vulvar, penile/vulvar, and oral/penile and genital HPV infection.
There are nonsexual means of HPV transmission by hand and inanimate objects that have been reported.
Because most HPV infections in men are asymptomatic and men are not routinely screened for HPV, heterosexual men may act as reservoirs for HPV infection, resulting in continued transmission of both high-risk and low-risk HPV DNA types to women.
If the HPV virus can be transmitted by fingers or inanimate objects, then it would also be expected that self/transference to the penis, scrotum to the perianal region or anal canal can also result from nonsexual as well as sexual behavior. This observation opens up a new explanation on how HPV infection can be spread on an individual (male or female) from one anatomic site to another.
Heterosexual men can get an anal HPV infection by massage in the area associated by the individual themselves or their partner. Anodigital insertion is also a factor that puts heterosexual men at increased risk for getting an anal HPV infection.
Anal HPV infections are also very common in sexually active women.
33% of heterosexual men with an HPV infection have a high-risk oncogenic type.
The same-sexual behavior is frequently viewed as highly socially stigmatized behavior and many men avoid acknowledging it. If there were men who incorrectly classify themselves as having only heterosexual contact when they actually had previous contacts with men would otherwise be classified as bisexual, the incidence of anal HPV infections in heterosexual men may be considered lower.
Men with only anal HPV infections had a high proportion of unclassified HPV types. Woman who have only anal HPV infections also have a higher proportion of unclassified HPV types, compared with woman with concurrent anal and cervical infections.
The factors associated with a heterosexual man having an increased change of acquiring an HPV infection include the lifetime number of female sexual partners, the frequency of sex during the preceding month, and lack of circumcision.
The prevalence of anal HPV infection in heterosexual men is 25%. This suggests that HPV may be a common anal infection in sexually active heterosexual men who develop anal warts.
