In short
Gonorrhea is a sexually transmitted infection that is most common in young adults, caused by bacteria that can infect the genital tract, mouth, or anus. The infection can be passed during vaginal, oral, or anal sex, or from a pregnant woman to her baby during childbirth. While it does not always cause symptoms, untreated infection can lead to prostate and testicle problems in men, and pelvic inflammatory disease, pregnancy problems, and infertility in women. Health care providers diagnose gonorrhea with lab tests, and treatment is with antibiotics, though treating it is becoming more difficult because drug-resistant strains are increasing.

Description
Gonorrhea is a sexually transmitted infection (STI). It is most common in young adults. The bacteria that cause gonorrhea can infect the genital tract, mouth, or anus. You can get gonorrhea during vaginal, oral, or anal sex with an infected partner. A pregnant woman can pass it to her baby during childbirth.
Gonorrhea does not always cause symptoms. In men, gonorrhea can cause pain when urinating and discharge from the penis. If untreated, it can cause problems with the prostate and testicles.
In women, the early symptoms of gonorrhea often are mild. Later, it can cause bleeding between periods, pain when urinating, and increased discharge from the vagina. If untreated, it can lead to pelvic inflammatory disease, which causes problems with pregnancy and infertility.
Your health care provider will diagnose gonorrhea with lab tests. Treatment is with antibiotics. Treating gonorrhea is becoming more difficult because drug-resistant strains are increasing. Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading gonorrhea. If your or your partner is allergic to latex, you can use polyurethane condoms. The most reliable way to avoid infection is to not have anal, vaginal, or oral sex.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
