Gonorrhoea is caused by Neisseria gonorrhoeae. It can be transmitted through vaginal, anal or oral sex and may be passed during childbirth. Infection is common and can occur without symptoms, particularly in the cervix, rectum or throat.
Gonorrhoea is the British spelling; American sources and most search results write it as gonorrhea. They are the same infection, and everything below applies to either spelling.
Because resistance patterns change over time, gonorrhoea is a good example of why medical articles must be updated. Readers should not be given a fixed antibiotic regimen as self-treatment advice; clinicians use current national guidelines and may need culture testing when treatment failure is suspected.
Gonorrhea, spelled gonorrhoea in many countries outside the United States, is a bacterial sexually transmitted infection that can affect the genitals, rectum, and throat. Symptoms can be noticeable, subtle, or entirely absent depending on the person and the body site involved.
Because throat and rectal gonorrhea are frequently easy to overlook, appropriate testing is based partly on sexual exposure rather than symptoms alone. A person may have infection at one site while a sample from another site is negative.
What it is and how it spreads
Gonorrhoea spreads when infected secretions contact susceptible mucosal surfaces. It can infect the urethra, cervix, rectum and throat. Condoms reduce risk but do not replace testing after a significant exposure or when a partner is diagnosed.
Gonorrhea spreads through sexual contact involving infected genital, rectal, or throat tissues and secretions. Transmission can occur during vaginal, anal, or oral sex, and ejaculation is not required for infection to pass between partners.
The bacteria can also be transmitted from a pregnant person to a baby during childbirth. Gonorrhea does not typically spread through ordinary household contact such as toilet seats, shared dishes, hugging, or casual touching.
Symptoms and silent infection
Many infections have no symptoms. Possible genital symptoms include burning urination, penile discharge, increased vaginal discharge or bleeding between periods. Rectal infection may cause itching, discharge, bleeding or painful bowel movements. Throat infection is often asymptomatic.
Genital gonorrhea symptoms may include burning with urination, unusual vaginal or penile discharge, bleeding between periods, pelvic discomfort, or pain or swelling in a testicle. Rectal infection can cause discharge, itching, soreness, bleeding, or painful bowel movements.
Throat gonorrhea may cause a sore throat but often produces no obvious symptoms. The absence of discharge, pain, or visible changes therefore cannot reliably rule out infection after a relevant exposure.
Testing and diagnosis
NAAT testing is commonly used with urine or swabs. Oral or anal exposure can require throat or rectal samples, which is why a genital-only test may not rule out infection at another site. When treatment failure is suspected, culture and antimicrobial-susceptibility testing may be important.
Gonorrhea testing commonly uses a laboratory method that detects genetic material from the bacteria. Samples can include urine or swabs from the vagina, cervix, rectum, or throat, depending on the anatomy and sites that may have been exposed.
In some circumstances, particularly when treatment failure or antibiotic resistance is a concern, a clinician may collect a culture. Culture can provide information about whether the bacteria remain present and which antibiotics are likely to work.
Treatment and recovery
Gonorrhoea is curable, but the recommended antibiotic regimen depends on current guidance, weight, allergy, pregnancy and whether chlamydia has been excluded. Persistent symptoms after treatment should be reassessed because resistance or another infection may be involved.
Gonorrhea requires prescription antibiotic treatment. Because the bacteria have developed resistance to multiple antibiotics over time, treatment recommendations are specific and may change as resistance patterns evolve; using leftover or non-prescribed antibiotics is not a reliable substitute for recommended care.
Follow the clinician's instructions about treatment, temporary sexual abstinence, and any follow-up testing. Persistent symptoms after treatment deserve reassessment because they can reflect reinfection, another condition, or less commonly an infection that has not responded as expected.
Partners, disclosure and reinfection
Partners exposed during the relevant period may need evaluation and treatment. Reinfection is common when partners are untreated or a new exposure occurs. Follow the clinic’s instructions about how long to avoid sex and whether retesting is recommended.
Recent sexual partners may need evaluation and treatment so that infection is not passed back and forth. A partner can have gonorrhea without symptoms, making symptom-based decisions about whether treatment is necessary unreliable.
Previous gonorrhea does not provide dependable protection against future infection. Retesting after treatment is commonly recommended because reinfection can occur even when the original infection was treated successfully.
Reducing future risk
Condoms, testing and prompt treatment reduce transmission. Anyone with a history of gonorrhoea should understand that treatment does not create immunity. Antibiotic stewardship matters: do not share medication or use incomplete leftover courses.
Consistent use of condoms and appropriate barriers during oral, vaginal, and anal sex can reduce exposure to gonorrhea. Barriers work best when used correctly throughout sexual contact rather than introduced only near ejaculation.
Testing at exposed body sites is also an important part of prevention and early detection. People who have ongoing exposure risks may benefit from regular screening according to current clinical recommendations.
Practical context and next steps
A useful way to interpret gonorrhoea information is to separate three questions: whether an exposure could have occurred, whether there are symptoms, and whether testing or treatment is indicated. Those questions are related but not interchangeable. A person can have a relevant exposure without symptoms, symptoms can have a non-STI cause, and a test can be negative if the wrong body site or timing is used. The sections on what it is and how it spreads and symptoms and silent infection should therefore be read together rather than as a symptom checklist.
If you speak with a sexual-health professional about gonorrhoea, be ready to describe the type of sexual contact, the body sites involved, when the contact occurred, whether a barrier was used, any symptoms, pregnancy status when relevant and whether a partner has received a diagnosis. You do not need a perfect sexual history or medical vocabulary. Clear practical details help the clinician select the right tests and interpret timing more accurately.
Partner conversations are easier when they focus on health action rather than blame. A result or symptom may not prove when an infection was acquired, and some infections can remain silent. If a partner may have been exposed, the most useful information is what the diagnosis or concern is, what the clinic recommends, whether testing or treatment is needed and when sexual contact can safely resume. Related pages such as STI Overview, STI Testing, Safer Sex can provide the next layer of context.
Online information cannot tell you whether you personally have gonorrhoea. It also cannot replace examination, laboratory testing or a clinician’s interpretation of window periods and previous treatment. Questions such as “Can gonorrhoea infect the throat?” and “Can gonorrhoea infect the rectum?” are useful starting points, but an individual answer may depend on details that a general article cannot see. Seek prompt care for pelvic or testicular pain, pregnancy, fever or persistent symptoms after treatment.
A positive gonorrhea test confirms infection at the sampled site but generally cannot determine exactly when the infection was acquired. Because asymptomatic infection is possible, a positive result does not by itself establish the timing of transmission within a relationship.
Gonorrhea can occur alongside other sexually transmitted infections. For that reason, clinicians may recommend additional STI testing based on sexual history, symptoms, pregnancy status, and the type of exposure involved.
A decision checklist for this topic
Before acting on anything you read here, run through this short check.
Before acting on information about gonorrhoea, make a short personal checklist. What exactly are you trying to prevent, understand or improve? Is the issue new or longstanding? Are there symptoms, pain, bleeding, pregnancy possibility, recent exposures, medicines or health conditions that change the decision? Which parts of the page — especially What it is and how it spreads, Symptoms and silent infection, Testing and diagnosis — apply directly to you, and which are only background information? This approach reduces the chance of taking one sentence out of context or assuming that a common possibility is automatically your diagnosis.
If you are still uncertain after reading, use the questions on this page to decide the next step rather than continuing to search indefinitely. Common starting questions include: Can gonorrhoea infect the throat?; Can gonorrhoea infect the rectum?; Can gonorrhoea be cured?. Write down the answer you already know and what remains unknown. Then use STI Overview, STI Testing, Safer Sex or an appropriate healthcare professional to fill the gap. Seeking care is especially important when the missing information depends on examination, a laboratory test, prescription treatment, pregnancy-specific advice or urgent timing.
When to get professional or urgent help
•Seek prompt care for pelvic or testicular pain, pregnancy, fever or persistent symptoms after treatment.
•Severe pelvic/testicular pain or serious systemic illness requires urgent assessment.
Safety note: If symptoms are severe, rapidly worsening or described above as urgent, use the appropriate local emergency or same-day healthcare service rather than waiting for an online answer.
Arrange testing if you develop possible gonorrhea symptoms, are told that a partner has gonorrhea, or have had a sexual exposure for which testing is recommended. Do not wait for symptoms if a clinician or public health service advises screening.
Prompt care is important for severe pelvic or abdominal pain, fever with pelvic symptoms, marked testicular pain or swelling, joint pain or swelling with a new rash or fever, or symptoms during pregnancy. These findings can require assessment for complications beyond an uncomplicated local infection.
Questions & Clear Answers
Yes. Throat infection can occur after oral sex and is often asymptomatic.

STI testing is not one universal test. Depending on the infection and exposure, a service may use urine, blood or swabs from the vagina, cervix, throat, rectum or another site. Testing too soon after exposure can miss some infections, so timing and repeat testing may matter.
How Do You Get Chlamydia? Symptoms, Testing, Treatment and Partner Care
Chlamydia is a common bacterial STI that is curable with appropriate antibiotics. It often causes no symptoms, so testing is important after relevant exposure or under screening recommendations. Untreated infection can cause complications, particularly in the reproductive tract.
Syphilis Symptoms: Stages, Testing, Treatment and Reinfection
Syphilis is a bacterial STI caused by Treponema pallidum. It is curable with appropriate antibiotics, but untreated infection can progress through stages and eventually affect the nervous system, eyes, ears, heart and other organs. Pregnancy requires particularly prompt testing and treatment because syphilis can be transmitted to the fetus.
