Genital warts are growths or bumps that appear:
- On the vulva
- In or around the vagina or anus
- On the cervix
- On the penis, scrotum, groin, or thigh
- In the mouth or throat (rare)
The warts may be raised or flat, single or multiple, small, or large. Some may cluster to form a cauliflower-like shape. This condition is one of the most common
sexually transmitted diseases
(STDs).
Most people will be exposed to a form of HPV at some point in their lives. Not everyone will become infected or develop symptoms.
Genital warts are caused by the
human papillomavirus
(HPV). HPV is a family of more than 80 common viruses. Many types of HPV cause harmless
skin warts. These warts are often found on the fingers or feet. Only a few types are thought to cause genital warts.
HPV is easily spread during oral, genital, or anal sex with an infected partner. About two-thirds of people who have sex with a partner who has genital warts will also develop them. Warts can take several weeks or months to appear.
Risk Factors
Risk factors for HPV and genital warts include:
- Age 15-30 years old
- Multiple sexual partners
- Women whose first male sexual partner has had two or more previous sexual partners
-
Sex without
condoms
- Sex at an early age
- Skin-to-skin contact with an infected partner
- Previous history of genital warts
- Pregnancy
- Smoking
-
Taking
oral contraceptives
Symptoms
Genital warts often look like fleshy, raised growths. They have a cauliflower shape, and often appear in clusters. Sometimes warts may not be easy to see with the unaided eye.
In women, warts may be found in the following areas:
- Vulva or vagina
- Inside or around the vagina or anus
- Cervix
In men, warts are less common. If present, they are usually found in these areas:
- Tip or shaft of the penis
- Scrotum
- Around the anus
While warts do not usually cause symptoms, the following may occur:
- Bleeding
- Itching
- Irritation
- Burning
- Secondary bacterial infection with redness, tenderness, or pus
Complications of HPV
Cancer
Most strains of HPV that produce genital warts do not cause cancer. But, certain strains may cause
cervical cancer. Less commonly, cancers of the vulva, anus, or penis occur.
For women, it is important to have
Pap tests, which can detect HPV-related problems, including cervical cancer. During the Pap test, a sample of cells is taken from the cervix. This sample can also be tested for HPV.
If you are a healthy woman, many professional health organizations offer these recommendations for screening:
- If you are aged 21-29 years—It is recommended that you have the Pap test every three years.
- If you are aged 30-65—It is recommended that you have the Pap test along with the HPV test every five years. (Or, you can continue to have just the Pap test every three years.)
- If you are aged 65 or older—You may be able to stop having Pap and HPV tests if you have had normal results (eg, three normal results in a row and no abnormal results in the past 10 years).
Your doctor can help determine the right screening schedule for you. For example, you will need to have Pap tests done more often if you have abnormal results or certain conditions
Pregnancy and Childbirth Complications
Genital warts may get larger during pregnancy. This may make it hard to urinate. Warts in or near the vaginal opening may also block the birth canal during delivery.
Diagnosis
Genital warts may be diagnosed by:
Visual Exam
A doctor can diagnose genital warts by looking at them. If external warts are found on a woman, then the cervix is usually also checked. A doctor may use a special solution to help find lesions that do not have classic features.
Pap Test
If you get abnormal Pap test results, this may indicate HPV. But, your doctor will order more accurate tests, like a
colposcopy, to diagnose HPV.
Colposcopy and Biopsy
During a colposcopy, the doctor uses a special device to see if warts are in the cervix and vagina. For a
biopsy, the doctor takes a tissue sample and tests it.
HPV Testing
During an
HPV test, a swab of cells from the affected area can be checked for certain types of HPV.
Treatment
Your treatment depends on the size and location of the warts. Treatment helps the symptoms, but does not cure the virus. The virus stays in your body. Warts or other problems may recur.
Treatments
may include:
Topical Treatments
Your doctor may recommend one of these medications to be applied to the affected areas:
Combining one of these treatments with cryosurgery or laser treatment may increase their effect.
Cryosurgery, Electrocautery, or Laser Treatment
Methods that instantly destroy warts include:
- Cryosurgery (freezing)
- Electrocautery (burning)
- Laser treatment
These methods are used on small warts and on large warts that have not responded to other treatment. A large wart can also be removed surgically. For warts that keep coming back, an antiviral drug, called alpha-interferon, can be injected into the wart.
Prevention
The only way to completely prevent HPV from spreading is to avoid physical contact with an infected partner.
Latex condoms may help reduce the spread of HPV infection and genital warts. Condoms are not 100% effective. They do not cover the entire genital area.
Other ways to prevent infection include:
- Abstaining from sex
- Having a monogamous relationship
- Getting regular check-ups for STDs
Vaccine
The
HPV vaccine, a series of three injections, is given to girls and boys aged 11-12 years old. If you are aged 26 or younger and were not vaccinated, you can receive a "catch-up" vaccine series.
Special Considerations
Genital warts are rare in children. This diagnosis may indicate sexual abuse. Abuse needs to be reported.
