What are genital warts?

Genital warts are a very common sexually transmitted infection (STI). They are caused by some types of the virus called human papillomavirus (HPV).

Genital warts are small lumps that you can see or feel. They can be found on your:

• vulva (the outside of the female genitals)
• vagina (female reproductive organ)
• cervix
• penis
• anus
• mouth

Genital warts are different from warts that you can get on your hands and knees.

What are the symptoms of genital warts?

Genital warts may:

• be itchy
• be bumpy or flat
• develop as a single wart
• develop in clusters that look like a small cauliflower

Genital warts may look different on different people.

You may also notice other symptoms such as:

• changes in your stream of urine (wee)
• blood in your urine
• blood in your stools (poo)

What causes genital warts?

Genital warts are caused by some types of human papillomavirus (HPV). They are contagious (spread easily from person to person).

You can catch HPV through:

• skin-to-skin contact during vaginal, anal or oral sex
• sharing sex toys
• contact with genital secretions (fluids)

The warts usually appear within 3 months of contact with someone infected with HPV, but it may take longer.

Some people who are infected with HPV do not have any symptoms and may not know they are infected. It is important to know that you can still spread HPV even if you do not have any symptoms.

There are many types of HPV. It is possible to be infected by more than one type of HPV.

Some types of HPV can cause cancers such as cervical cancer and anal cancer. The types of HPV that cause genital warts are unlikely to cause cancer.

If you are pregnant and have genital warts, it is unlikely that you will pass HPV to your baby during labour and birth.

When should I see my doctor?

You should visit your doctor for a sexual health check if you:

• see or feel any unusual lumps on your genitals
• have any other symptoms of genital warts
• have had sex with someone who has genital warts

If you have warts inside your anus, you might need to see a surgeon. If you have warts on your cervix, you might need to see a gynaecologist.

How are genital warts diagnosed?

Your doctor can usually diagnose genital warts by looking at them.

If the warts look a bit unusual, your doctor may recommend a biopsy to make sure they are not cancer.

Your doctor may also suggest an STI check.

How are genital warts treated?

Genital warts may be treated with:

• cream
• wart paint (liquid medication that peels away warts)
• liquid nitrogen (cryotherapy)
• laser treatment
• surgical removal

During pregnancy, some of these treatments are not recommended. Your doctor will suggest a treatment option that is best for you.

If you have warts in your pubic area, avoid shaving or waxing as this could spread the infection.

Treating your warts does not cure the infection. Treatments get rid of the warts that you can see. Some people choose to treat their warts because they do not like how they look or because other symptoms bother them. Other people choose to leave them alone.

For some people, the warts can go away on their own. However, if you have a weak immune system, they may not go away.

Treatments for other types of warts are not suitable for genital warts. See your doctor to discuss treatment options.

Coping with genital warts

Finding out you have genital warts can be upsetting. You may feel alone, embarrassed, anxious and afraid of rejection or worried about not being sexually desirable.

It is important to keep in mind that genital warts are a common STI.

If you are worried about telling recent sexual partners that you have genital warts, you can send them an anonymous text message or email through some websites, such as Let Them Know.

You may find it helpful to talk to a parent or a friend you trust. There are organisations that can support you. These are different in every state and territory. The health.gov.au website can help you find sexual health services in your state or territory.

What are the complications of genital warts?

Some types of HPV that cause genital warts can also cause a very rare complication called recurrent respiratory papillomatosis (RRP). RRP causes warts to develop in your airways and lungs. RRP can occur in adults with genital warts (known as 'adult-onset') or in children (called 'juvenile-onset') born to a person who had genital warts during pregnancy.

If you have genital warts, you are most likely not at higher risk of cancers in the genital area. Around 90% of genital warts are caused by types of HPV that do not lead to cancer.

Can genital warts be prevented?

You can reduce your chance of becoming infected with HPV by:

• getting the HPV vaccine, which protects against some types of HPV that cause genital warts
• using condoms with new and casual sexual partners
• having regular STI checks

Condoms do not completely protect against HPV as they do not cover all the skin in your genital area.

If you have a cervix, are aged 25 to 74 and have ever been sexually active, you should have a cervical screening test every 5 years. The cervical screening test detects HPV and has replaced the Pap smear.
