In the United States, there are no FDA-approved tests clinically available to detect HPV infection of oropharyngeal, anal, or male genital specimens.
Even though men play a key role in the transmission of HPV to women, and can develop forms of cancer caused by HPV, we have still limited information on HPV infection in men and on the appropriate diagnostic workup that must be applied to detect HPV infection.
The test that is considered more reliable, though not approved nor recommended, requires swab sampling of the glans, penile shaft, and scrotum.
Nonetheless since the genital infection can affect any site, no one knows the optimal sampling site, and false negative results are very common.
Does HPV go away?
Most HPV infections clear naturally with little or no inconvenience, but some types of HPV may cause persistent infections that put at a higher risk of developing a cancer.
Recurrent genital warts may happen when the HPV infection does not clear on its own. However a positive result on an HPV test is not necessarily a cause of concern.
Genital warts left untreated may spread to other areas and increase in size and number. In most cases genital warts do not go away on their own and should be evaluated by a doctor as soon as they appear.
So is HPV dangerous for my health?
Genital warts are 90% of the times caused by HPV types that do not typically cause cancer.
Other HPV strains are considered “carcinogenic” viruses, i.e. they can cause cancer.
For instance, Papillomavirus infection is recognized as the main cause of cervical cancers in women but it has been associated also to penile, vaginal, vulvar, anal and oropharyngeal cancers.
It has been estimated that in 2009 alone, 32 000 cases of cancer in USA were attributable to HPV infection. Luckily the transformation to cancer takes several years (more than 10 usually), thus we have many chances to detect and treat early HPV related forms of cancer.
Regular visits with a gynecologist for women, consultations with a urologist for men, and visits with a proctologist for both are crucial in detecting early signs of an HPV related cancer.
Can genital warts be prevented?
Yes. Abstaining from sex with someone with HPV would be the best way to protect yourself, but it’s not easy since most people don’t know to have the virus.
Using condoms can help, but they are not as effective as they usually are in other STDs (the virus can infect areas outside the condom).
There are now HPV vaccines that help keep people from getting infected.
Of course they work best when are administered before being infected by HPV (ideally before the first sexual intercourse), but can be helpful also later on. There are three different HPV vaccines available.
All of them come in shots and require three doses over 6 months. Children can get the vaccine any time from age 9 up to 26 (the sooner the better).
Women should not get the vaccine if they are pregnant and should continue to be checked anyway on a routine schedule for cervical cancer with regular Pap-smear starting at 21 years old (no vaccine is perfect!).
Is there a genital warts treatment?
Although not dangerous, genital warts can be sometimes be difficult and costly to remove, thus they can be debilitating to young couples.
Warts removal can be performed using various chemical agents (some are self-administered and some can be applied only by a doctor) or, better, through physical destruction (surgery, cryotherapy, laser or cautery) under local anesthesia.
