Genital warts, sometimes called venereal warts, are growths or bumps contracted through sexual contact. They're caused by certain types of the human papillomavirus (HPV), which is one of the most common sexually transmitted diseases (STDs).
Symptoms
In females, genital warts appear in and around the vagina or anus or on the cervix. In males, they appear on the penis, scrotum, groin, or thigh. Genital warts can be raised or flat, small or large. Sometimes they're clustered together in a cauliflower-like shape. Most of the time, they're flesh-colored and painless. Sometimes, the warts are so small and flat that they may not be noticed right away.
It may take several months or years after infection for symptoms to appear — if there are symptoms at all.
In females, the virus can lead to changes in the cervix that may lead to cancer, so it's important that it is diagnosed and treated as soon as possible. Males infected with HPV can also be at risk for cancer of the penis and the anus.
Contagiousness
Genital warts are transmitted through sexual contact (anal, oral, and vaginal) with an infected person, and warts can appear within several weeks or months afterwards.
The virus is passed through skin-to-skin contact, but not everyone who's been exposed to the virus will develop genital warts.
Prevention
A vaccine for females 9 to 26 years old is approved to prevent HPV infection, which causes most cervical cancers and genital warts. The vaccine, called Gardasil, is given as three injections over a 6-month period. It doesn't protect females who've already been infected with HPV, and doesn't protect against all types of HPV, so be sure your daughter gets routine checkups and gynecologic exams. If you have questions about the vaccine, talk with your doctor.
Because genital warts are spread through sexual contact, the best way to prevent them is to abstain from having sex. Sexual contact with more than one partner or with someone who has more than one partner increases the risk of contracting any STD.
When properly and consistently used, condoms decrease the risk of STDs. Latex condoms provide greater protection than natural-membrane condoms. The female condom, made of polyurethane, is also considered effective against STDs.
Using douche can actually increase a female's risk of contracting STDs because it can change the natural flora of the vagina and may flush bacteria higher into the genital tract.
A teen who is being treated for genital warts also should be tested for other STDs, and should have time alone with the doctor to openly discuss issues like sexual activity. Not all teens will be comfortable talking with parents about these issues. But it's important to encourage them to talk to a trusted adult who can provide the facts.
Treatment
Though there's no cure for an HPV infection, the genital warts can be treated and removed with prescription medication or other medical procedures, such as freezing or laser treatments.
Because the HPV remains dormant in the body, genital warts may reappear at any time after treatment. Those who have had one outbreak of genital warts still carry the virus and can infect others. Someone who has had HPV can also get a new HPV infection from another partner.
Getting Help
If your teen is thinking of becoming sexually active or already has started having sex, it's important to talk with him or her about it. Make sure your teen knows how STDs can be spread (during anal, oral, or vaginal sex) and that these infections often don't have symptoms, so a partner might have an STD without knowing it.
It can be difficult to talk about STDs, but just as with any other medical issue, teens need this information to stay safe and healthy. Provide the facts, and let your child know where you stand.
It's also important that all teens have regular full physical exams — which can include screening for STDs. Your teen may want to see a gynecologist or a specialist in adolescent medicine to talk about sexual health issues. Community health organizations and sexual counseling centers in your local area also may be able to offer some guidance.
