Human Papillomavirus (HPV) is a common viral infection transmitted primarily through sexual contact, making it one of the most widespread sexually transmitted infections globally. While public discussion often focuses on its impact on women, particularly regarding cervical cancer, HPV also poses health implications for men. Understanding how HPV manifests in men and available testing approaches is important for managing this common infection. This article explores current testing methods for men.
Understanding HPV in Men
HPV in men presents differently depending on the specific strain. Some types of HPV are low-risk, typically causing benign growths like genital warts. These warts can appear on the penis, scrotum, or around the anus, and while generally painless, may cause itching or tenderness. Other HPV strains are high-risk, potentially leading to certain cancers.
High-risk HPV types are associated with cancers of the anus, penis, and oropharynx (throat, including the base of the tongue and tonsils). Though less common than cervical cancer in women, these cancers represent significant health concerns for men. Oral and throat cancers are among the most common HPV-related cancers in men, with over 13,000 new cases diagnosed annually in the U.S.
Globally, genital HPV infection in men is estimated at 31% for any HPV type and 21% for high-risk types. Many infected men may not experience symptoms, as their immune system often clears the virus within one to two years.
Current Testing Approaches for Men
No routine, FDA-approved screening test for HPV in men exists, comparable to the Pap test for women. Instead, HPV testing in men is primarily diagnostic, performed when symptoms are present or specific risk factors exist. Methods focus on detecting the virus or cellular changes it causes, rather than broad screening.
Visual inspection is a primary diagnostic method for visible lesions like genital warts. A healthcare provider examines the genital area, sometimes applying a vinegar solution to help identify less visible warts. This method is not always definitive. If a suspicious lesion is not clearly a wart or raises concern for precancerous changes, a biopsy may be performed. This involves taking a tissue sample for microscopic examination to confirm HPV presence and assess for abnormal cells.
Anal HPV testing is an established practice for certain high-risk populations, particularly men who have sex with men (MSM). This can involve an anal Pap test, where cells are collected and examined for abnormalities, or an HPV DNA test to detect the virus directly. Oral HPV testing can be considered for specific concerns in the mouth or throat, though it is less common for general screening. Urethral or penile swabs can also detect HPV DNA, but are generally used in research or specific clinical scenarios, not for routine screening. This is partly due to challenges in obtaining consistent samples and the virus often residing in deeper tissues.
When Testing is Recommended
HPV testing is not a standard part of routine check-ups for asymptomatic men. Testing is typically recommended under specific circumstances, such as a clinical indication or elevated risk of HPV-related disease. The most common reason for testing is visible lesions, such as genital warts.
Men experiencing unexplained itching, bleeding, or discomfort in genital or anal areas may also warrant HPV evaluation. For high-risk groups like men who have sex with men (MSM), anal HPV screening may be considered due to their increased risk of anal cancer. If a male’s sexual partner has been diagnosed with a high-grade cervical lesion, cervical cancer, or other HPV-related disease, testing may be discussed for risk assessment or contact tracing.
Interpreting Test Results and Next Steps
Understanding HPV test results involves recognizing what findings signify and what actions may follow. A positive test result, especially from a biopsy, indicates HPV presence and potentially associated cellular changes or lesions. If low-risk HPV types causing genital warts are identified, treatment focuses on removing them, which can include topical medications or physical removal. For high-risk HPV types, a positive result may prompt closer monitoring or further evaluation for precancerous lesions, particularly in high-risk areas.
Conversely, a negative result means HPV DNA was not detected or no visible lesions were present. Current testing methods have limitations; a negative result does not guarantee the absence of all HPV types, nor does it predict future infection or disease. The virus can also be subclinical, meaning it is present without causing visible symptoms. Healthcare providers will discuss results, explain implications, and recommend personalized management plans. These may include continued monitoring, symptom treatment, or preventive measures like vaccination.
