HPV in Men: Risks, Symptoms, and Prevention

Human papillomavirus (HPV) is a common sexually transmitted virus affecting the skin and mucous membranes. It includes low-risk types that cause genital warts and high-risk types linked to cancers such as penile, anal, and throat cancers.

Although HPV is often associated with women's health, it also poses risks for men, as many sexually active individuals may contract the virus at some point in their lives.

Many men are asymptomatic, unknowingly spreading the virus. Unlike women, men currently lack routine screening options for HPV, which can delay the detection of HPV-related conditions and may increase the risk of complications.

Awareness is essential because HPV often goes unnoticed in men, heightening the risk of transmission and severe health issues like cancer.

Vaccination and preventive measures can significantly reduce these risks, helping men take proactive steps to protect themselves and their partners.

Modes of Transmission of HPV

HPV spreads primarily through direct contact with infected skin or mucous membranes. The most common mode is sexual contact, including vaginal, anal, and oral sex.

Notably, the virus can be transmitted even if no symptoms are visible in the infected individual. Skin-to-skin contact involving the genital area may result in transmission, even without intercourse.

Less common methods of transmission include:

Non-Sexual Skin Contact: Direct contact with areas infected by HPV outside the genital region.
Contaminated Objects: In rare instances, shared personal items such as razors or sex toys have been reported as potential sources of HPV transmission.
Perinatal Transmission: In some cases, HPV can pass from mother to child during vaginal delivery, potentially causing warts in the infant's throat (laryngeal papillomatosis).

Risk Factors Associated with HPV Transmission

Several factors increase the likelihood of HPV infection in men:

Multiple Sexual Partners: Having numerous partners significantly raises the risk of exposure to the virus.
Unprotected Sex: Not using condoms or dental dams increases the chance of transmission. While these methods reduce risk, they do not entirely prevent HPV, as the virus can infect areas not covered.
Weakened Immune System: Men with conditions like human immunodeficiency virus (HIV) or those undergoing treatments such as chemotherapy are less able to clear HPV naturally.
Lack of Vaccination: Without the HPV vaccine, men are more vulnerable to both high-risk and low-risk strains of the virus.
Smoking: Smoking tobacco weakens the immune system and is linked to higher rates of persistent HPV infections and HPV-related cancers.

Symptoms of HPV in Men

HPV often presents no symptoms in men, making it difficult to detect without specific tests. Many men infected with HPV may remain completely unaware of their condition, as their immune systems may suppress or clear the virus without causing visible signs.

However, during this time, they can unknowingly transmit the virus to others through sexual or skin-to-skin contact.

The often asymptomatic nature of HPV highlights the importance of prevention through vaccination and safe practices to reduce transmission and potential health risks.

When HPV causes symptoms, they depend on the strain of the virus.

Genital warts, linked to low-risk HPV appear as small, flesh-colored, or raised bumps on the penis, scrotum, anus, or surrounding areas. Though painless, they may cause itching or discomfort.

High-risk HPV strains can lead to unusual lumps or sores in the genital or anal areas, which may indicate precancerous changes and should be evaluated by a healthcare provider.

While not life-threatening, these symptoms can cause distress and may require medical treatment.

Serious Health Risks

High-risk HPV types are associated with several cancers in men, particularly when the infection persists.

Penile Cancer

HPV is a significant cause of penile cancer, although it is relatively rare. Early signs include persistent sores, growths, or discoloration on the penis.

Anal Cancer

HPV-related anal cancer is more common in men who have sex with men (MSM) and those with weakened immune systems. Symptoms may include rectal bleeding, pain, or lumps around the anus.

Oropharyngeal Cancer (Throat Cancer)

HPV infections in the mouth or throat, typically acquired through oral sex, can lead to cancers of the oropharynx (back of the throat, including the base of the tongue and tonsils).

Symptoms may include persistent sore throat, difficulty swallowing, or unexplained lumps in the neck.

HPV-related cancers in men are less common than in women but are increasing, especially throat cancers. Early detection and treatment of symptoms are crucial to improve outcomes.

Diagnosis of HPV in Men

Diagnosing HPV in men can be complex due to the lack of routine screening tools. However, specific methods are available to identify symptoms or related conditions.

Physical Examination

A healthcare provider examines the genital, anal, or throat areas for visible signs such as genital warts, unusual lumps, sores, or lesions that may indicate an HPV infection or related complications.

HPV DNA Testing

Unlike women, men do not have an FDA-approved HPV DNA test for routine screening. However, anal Pap testing for HPV DNA is sometimes used in high-risk groups, such as individuals with weakened immune systems, to identify high-risk HPV types.

HPV-Linked Cancer Screenings

For men at higher risk, such as those with HIV, anal Pap tests may be recommended to detect precancerous changes. Additionally, screening for oropharyngeal cancers may involve imaging or biopsy if symptoms like persistent sore throat, difficulty swallowing, or unexplained neck lumps are present.

Prevention and Vaccination

Preventing HPV in men involves two primary strategies: vaccination and adopting safe behaviors.

These measures significantly lower the risk of infection, transmission, and HPV-related health complications such as genital warts and cancers.

HPV Vaccination for Men

The HPV vaccine has been proven effective in preventing the most harmful strains of the virus. It protects against types of HPV that cause genital warts and cancers such as anal, penile, and throat cancers.

Effectiveness

The vaccine prevents over 90% of HPV-related cancers and genital warts when given before exposure to the virus.

It offers substantial protection to sexually active individuals who have not yet encountered all the strains covered by the vaccine.

Age Recommendations

Routine HPV vaccination is recommended for boys aged 11–12 and can be administered as early as age 9.

Catch-up vaccination is recommended for men up to age 26 who did not receive the vaccine earlier.

Adults aged 27–45 may discuss the potential benefits of HPV vaccination with their healthcare provider, particularly if they are at higher risk due to factors such as multiple sexual partners, being a man who has sex with men, or having a weakened immune system.

Key Benefits

Reduces the risk of developing HPV-related cancers and genital warts.
Lowers the risk of transmitting HPV to sexual partners, contributing to broader community protection.
Provides long-term immunity against targeted HPV types, decreasing reinfection risks.

Behavioral and Lifestyle Preventive Measures

Beyond vaccination, adopting healthy practices further reduces the risk of HPV infection and complications.

Practice Safe Sex

Use condoms or dental dams consistently during sexual activity. Although not foolproof, these barriers lower the risk of transmission by limiting direct contact with infected areas.

Limit Sexual Partners

Reducing the number of sexual partners decreases exposure to HPV, lowering the risk of infection.

Regular Health Check-Ups

Schedule routine check-ups, especially for men at higher risk (e.g., those with weakened immune systems or who engage in receptive anal intercourse). This ensures early detection and management of potential HPV-related conditions.

Avoid Smoking

Smoking weakens the immune system, increasing the likelihood of persistent HPV infections and related cancers. Avoiding smoking strengthens the body's ability to fight infections.

Maintain a Healthy Immune System

A robust immune system can naturally clear HPV, supported by a balanced diet, regular exercise, effective stress management, and sufficient sleep.

Treatment Options for HPV in Men

Although there is no cure for HPV, its symptoms and complications, including genital warts and HPV-related cancers, can be effectively managed with targeted treatments. Early detection and timely medical care are key to achieving the best outcomes.

Symptomatic Treatment

Treatments for visible symptoms focus on removing genital warts and managing discomfort. Common options include:

Topical Treatments

Prescription creams such as imiquimod or podofilox can be applied to small external warts. These medications either boost the immune system to fight the virus or destroy wart tissue.

Cryotherapy

This procedure involves freezing warts with liquid nitrogen to destroy the tissue. It is highly effective but may require multiple sessions for complete removal.

Surgical Removal

Minor surgical procedures, such as excision, laser therapy, or electrocautery, can remove persistent or large warts. These options are often used when other treatments fail.

Management of HPV-Related Health Risks

For men with complications like cancers or chronic conditions, management involves early detection, targeted treatment, and ongoing care:

HPV-Related Cancers

Anal cancer treatment strategies depend on the stage and may involve surgery to remove cancerous tissue, radiation therapy, or chemotherapy for advanced cases.

Regular anal Pap smears are essential for high-risk individuals to detect precancerous changes early and improve treatment outcomes.

Penile cancer is treated primarily with surgery, ranging from localized tissue removal to more extensive procedures for advanced stages. Radiation therapy or chemotherapy may be necessary for severe cases to control the disease.

HPV-related oropharyngeal cancer, affecting the throat, base of the tongue, and tonsils, is treated with a combination of surgery, radiation therapy, and chemotherapy. Early symptoms like persistent sore throat, difficulty swallowing, or neck lumps require prompt medical attention for timely treatment.

Monitoring and Follow-Up

Regular check-ups, including imaging, biopsies, or blood tests, are critical for monitoring cancer recurrence or progression.

Supportive and Psychological Care

Living with HPV-related conditions can be emotionally challenging. Mental health counselors or support groups can help individuals cope with the stress of treatment and recovery.

Lifestyle Changes

Maintaining a strong immune system through healthy lifestyle practices, such as avoiding smoking, eating a balanced diet, exercising regularly, and managing stress, may support overall health.
