Understanding Genital Warts

Genital warts are benign skin growths caused by certain strains of the human papillomavirus (HPV), most commonly types 6 and 11. They typically appear on the external genitalia, perineum, and around or inside the anus. Many people carry HPV without symptoms, but visible warts can be distressing and may affect sexual relationships and self-confidence.

Transmission occurs through direct skin-to-skin contact during sexual activity. HPV can be shed from the skin even when warts are not visible, so transmission may occur unknowingly. Condoms reduce risk but do not provide complete protection since they may not cover all affected skin areas.

Warts are usually painless but can itch, bleed when irritated, or cause discomfort. The number, size and distribution of warts vary: some people have a single small lesion; others develop multiple clustered growths that can resemble cauliflower in appearance.

Diagnosis is generally clinical following examination by a healthcare professional. Internal warts (e.g., in the cervix or anal canal) may require specialist assessment and, occasionally, further tests to rule out co-existing conditions.

• Soft, flesh-coloured bumps
• Single or clustered lesions
• Itching or mild discomfort
• Bleeding if abraded
• May be internal and not visible

Causes and Risk Factors

Genital warts are caused by low-risk HPV strains. Risk factors include early sexual activity, multiple sexual partners, inconsistent condom use, and immune suppression. Smoking has been associated with a reduced ability to clear HPV and higher rates of persistent infection.

Pregnancy and hormonal changes can influence wart growth: warts may enlarge or become more noticeable during pregnancy due to immune modulation.

• Unprotected sexual contact
• Multiple sexual partners
• Weakened immune system
• Smoking
• Not vaccinated against HPV

Symptoms and When to Seek Help

Symptoms range from asymptomatic small bumps to clusters causing irritation. Seek medical advice if you notice new lumps in the genital area, if lesions bleed, increase in number, cause pain, or recur after treatment. Pregnant people should notify their clinician as some treatments are contraindicated in pregnancy.

Treatment Options

Treatment targets removal of visible warts and relief of symptoms. Prescription topical therapies such as podophyllotoxin (a cytotoxic agent) and imiquimod (an immune response modifier) are commonly used. These creams are applied over weeks according to specific regimens and can be effective for many patients.

Clinic-based procedures include cryotherapy (freezing with liquid nitrogen), surgical excision, or electrosurgery. Choice of treatment depends on wart size, location, patient preference, pregnancy status, and clinician experience. It’s important to follow up, as recurrence is possible.

• Topical podophyllotoxin or imiquimod
• Cryotherapy in clinic
• Surgical removal for large lesions
• Avoid sexual contact during active lesions
• HPV vaccination to reduce future risk

Prevention and Long-Term Care

Prevention focuses on vaccination, safer sexual practices, and overall immune health. The HPV vaccine protects against the strains most commonly responsible for genital warts and is a key preventive tool. Regular STI screening and open communication with sexual partners help reduce transmission.
