What Are Genital Warts? Causes, Symptoms, and Treatment

Genital warts, a common sexually transmitted infection (STI), are caused by certain strains of the human papillomavirus (HPV). Affecting both men and women, genital warts can lead to discomfort, emotional distress, and other health complications if left untreated. This blog post will delve into what genital warts are, how they are transmitted, their symptoms, and available treatment options.

Understanding Genital Warts

Genital warts are soft growths that appear on the genital and anal regions. They can vary in size and shape, appearing as small, flesh-colored bumps or as larger, cauliflower-like growths. The warts may appear singly or in clusters and can be flat, raised, or shaped like tiny stalks. While genital warts are usually painless, they can cause itching, discomfort, and bleeding, particularly if they are irritated.

Causes of Genital Warts

Genital warts are caused by the human papillomavirus (HPV), specifically by low-risk strains like HPV-6 and HPV-11. These strains of the virus are responsible for approximately 90% of genital warts cases. Unlike high-risk strains of HPV that can lead to cancers such as cervical cancer, low-risk strains typically cause benign warts on the skin.

HPV is highly contagious and spreads through direct skin-to-skin contact during sexual activity, including vaginal, anal, and oral sex. It is important to note that genital warts can still be transmitted even when warts are not visible, as the virus can be present on the skin without causing symptoms.

Who Is at Risk?

Anyone who is sexually active can contract genital warts, but certain factors increase the risk:

• Unprotected Sex: Engaging in sexual activity without using condoms or dental dams increases the risk of contracting HPV.
• Multiple Sexual Partners: Having multiple sexual partners or a partner who has had many sexual partners raises the likelihood of exposure to the virus.
• Young Age: Individuals under 30 are more likely to contract HPV, partly due to higher sexual activity and lower immunity.
• Weakened Immune System: Those with weakened immune systems, such as people with HIV or those taking immunosuppressive medications, are at higher risk.
• Smoking: Smoking has been associated with a higher risk of contracting HPV and developing genital warts.

Symptoms of Genital Warts

The symptoms of genital warts can vary depending on the location, size, and number of warts. Some common symptoms include:

• Small, Flesh-Colored Bumps: The warts often appear as small, flesh-colored or greyish bumps on the genital or anal area.
• Clusters of Warts: Warts can cluster together, forming a shape similar to cauliflower.
• Itching or Discomfort: Warts may cause itching or discomfort, especially if they are irritated by clothing or sexual activity.
• Bleeding During Intercourse: In some cases, warts can cause bleeding during or after sexual intercourse.
• No Symptoms: Many people with genital warts do not experience any noticeable symptoms, especially if the warts are small or located inside the genital tract.

Diagnosis of Genital Warts

Genital warts are typically diagnosed through a physical examination. A healthcare provider can usually identify the warts by their appearance. In some cases, additional tests may be conducted to confirm the diagnosis or check for other sexually transmitted infections (STIs):

• Pap Smear: For women, a Pap smear may be performed to detect changes in the cervix caused by HPV.
• HPV DNA Test: This test can identify the presence of high-risk HPV strains that are associated with cervical cancer.
• Biopsy: In rare cases, a small sample of tissue may be taken from the wart for further examination under a microscope.

Treatment Options for Genital Warts

While genital warts can sometimes go away on their own, treatment is often recommended to remove the warts, alleviate symptoms, and reduce the risk of spreading the virus. Treatment options include:

1. Topical Medications

• Imiquimod (Aldara, Zyclara): This cream boosts the immune system’s ability to fight the virus. It is applied directly to the warts several times a week.
• Podofilox (Condylox): This solution works by destroying the tissue of the warts. It is applied twice a day for three days, followed by a four-day break.
• Sinecatechins (Veregen): An ointment derived from green tea extract, sinecatechins is applied three times a day and is particularly effective for external warts.

2. Cryotherapy

• Freezing with Liquid Nitrogen: This procedure involves freezing the warts with liquid nitrogen, causing them to blister and eventually fall off. Cryotherapy is usually done in a healthcare provider’s office and may require multiple treatments.

3. Electrocautery

• Burning Off Warts: Electrocautery uses an electrical current to burn off the warts. This procedure is usually performed under local anesthesia and may result in scarring.

4. Laser Treatment

• Using Laser Energy: Laser treatment uses a focused beam of light to destroy the wart tissue. It is often used for larger or more difficult-to-treat warts. This procedure can be costly and is typically reserved for severe cases.

5. Surgical Removal

• Excision: In some cases, warts are surgically removed using a scalpel or other surgical tools. This option is usually reserved for large warts or warts that have not responded to other treatments.

Preventing Genital Warts

Preventing genital warts primarily involves reducing the risk of HPV infection. Some key prevention strategies include:

1. HPV Vaccination

• Gardasil and Cervarix: The HPV vaccine protects against the most common strains of HPV that cause genital warts and cervical cancer. It is recommended for both males and females, ideally before becoming sexually active.

2. Use of Condoms

• Barrier Protection: Using condoms or dental dams during sexual activity can significantly reduce the risk of HPV transmission, although it is not 100% effective as HPV can be present on areas not covered by a condom.

3. Limiting Number of Sexual Partners

• Reducing Exposure: Having fewer sexual partners reduces the likelihood of encountering HPV. It is also important to communicate with partners about STIs and HPV status.

4. Regular Health Screenings

• Routine Check-ups: Regular screenings, such as Pap smears and HPV tests, can help detect HPV-related issues early, allowing for timely treatment and management.

Living with Genital Warts

Living with genital warts can be challenging, both physically and emotionally. The stigma associated with STIs can lead to feelings of shame, embarrassment, and anxiety. However, it is important to remember that genital warts are a common condition, and treatment is available.

If you have been diagnosed with genital warts, it is important to follow your healthcare provider’s advice for treatment and management. Open communication with sexual partners is also crucial to prevent the spread of the virus. Support groups and counseling can also be beneficial for coping with the emotional impact of the condition.

Genital warts are a common STI caused by certain strains of HPV. While they can cause discomfort and emotional distress, they are treatable with various medical interventions. Understanding the causes, symptoms, and treatment options for genital warts can help you make informed decisions about your sexual health. Prevention through vaccination, safe sex practices, and regular health screenings is key to reducing the risk of contracting or spreading HPV.
