Genital warts, also known as venereal warts or condylomata acuminata, are one of the most common types of sexually transmitted diseases.

As the name suggests, genital warts affect the moist tissues of the genital area. They may look like small, flesh-colored bumps or have a cauliflower-like appearance. Genital warts may be very small, or they may multiply into large clusters.

Although genital warts can be treated with medications and surgery, they are a serious health concern. The virus that causes genital warts — the human papillomavirus (HPV) — has been associated with cervical cancer. It has also been linked with other types of genital cancers.

In women, genital warts can grow on the vulva, the walls of the vagina, the area between the external genitals and the anus, and the cervix. In men, they may occur on the tip or shaft of the penis, the scrotum or the anus. Genital warts can also develop in the mouth or throat of a person who has had oral sexual contact with an infected person.

The signs and symptoms of genital warts include:

• Small, flesh-colored or gray swellings in your genital area
• Several warts close together that take on a cauliflower shape
• Itching or discomfort in your genital area
• Bleeding with intercourse

Often, genital warts cause no symptoms. They may be so small and flat that they can't be seen with the naked eye. Sometimes, however, genital warts may multiply into large clusters.

Pregnancy may sometimes trigger a dormant infection, or an active infection may worsen during pregnancy.
