Gonorrhoea: Symptoms, Transmission, Testing, Treatment and Prevention

Gonorrhoea is a common sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae.

It can infect several parts of the body, including the:

• cervix,
• urethra,
• rectum,
• throat,
• and, less commonly, eyes.

Gonorrhoea is primarily transmitted through vaginal, oral or anal sexual contact with someone who has the infection.

A pregnant person with untreated gonorrhoea can also transmit the infection to their baby around the time of childbirth.

Gonorrhoea can usually be cured with appropriate antibiotics. However, antibiotic resistance has become a serious worldwide concern, making accurate diagnosis and appropriate treatment increasingly important.

Can You Have Gonorrhoea Without Knowing?

Yes.

One of the most important facts about gonorrhoea is that it does not always cause symptoms.

This is particularly common among women.

Infections of the throat and rectum may also produce no noticeable symptoms.

Someone without symptoms can still:

• have gonorrhoea,
• transmit it to sexual partners,
• and develop complications.

This is why testing is important for people who may have been exposed.

How Is Gonorrhoea Transmitted?

Gonorrhoea can be transmitted during:

• vaginal sex,
• anal sex,
• and oral sex.

Transmission occurs when infected genital or other sexual fluids and tissues come into contact with susceptible mucous membranes.

Gonorrhoea can infect the genitals, rectum or throat depending on the type of sexual exposure.

Can Gonorrhoea Spread Without Ejaculation?

Yes.

Ejaculation does not need to occur for gonorrhoea to be transmitted.

The bacteria can be present in genital secretions and infected tissues.

Using condoms and other appropriate barrier methods correctly can substantially reduce the risk.

Can Gonorrhoea Spread Through Kissing?

Ordinary gonorrhoea is primarily transmitted through sexual contact involving infected genital, anal or throat sites.

Research continues into the importance of saliva and kissing in transmission of throat gonorrhoea, but vaginal, anal and oral sexual contact remain the major recognized routes.

Can You Catch Gonorrhoea From a Toilet Seat?

Gonorrhoea is not normally transmitted through toilet seats or ordinary casual contact.

You do not typically get gonorrhoea from:

• hugging,
• sharing food,
• sharing ordinary household objects,
• swimming pools,
• or sitting on a toilet seat.

Neisseria gonorrhoeae is adapted to living in the human body and transmission generally requires appropriate intimate contact.

Gonorrhoea Symptoms in Men

Some men develop noticeable symptoms.

Common symptoms can include:

• burning or pain when urinating,
• white, yellow or green discharge from the penis,
• and pain or swelling in one or both testicles.

Testicular symptoms occur less commonly than urethral symptoms but require appropriate medical assessment.

Some men have mild symptoms or none at all.

Gonorrhoea Symptoms in Women

Many women with gonorrhoea have no noticeable symptoms.

When symptoms occur, they may include:

• increased or unusual vaginal discharge,
• burning or pain when urinating,
• bleeding between menstrual periods,
• bleeding after sex,
• and sometimes pelvic or lower abdominal discomfort.

These symptoms can be mistaken for:

• a urinary tract infection,
• vaginal infection,
• or another reproductive-health condition.

Testing is therefore important rather than diagnosing gonorrhoea from symptoms alone.

Rectal Gonorrhoea

Gonorrhoea can infect the rectum after sexual exposure.

Rectal infection may cause no symptoms.

When symptoms occur, they can include:

• anal itching,
• soreness,
• discharge,
• bleeding,
• and painful bowel movements.

People can have rectal gonorrhoea without simultaneously having obvious genital symptoms.

Gonorrhoea in the Throat

Gonorrhoea can infect the throat, particularly following oral sexual exposure.

This is known as pharyngeal gonorrhoea.

Most throat infections cause no symptoms.

When symptoms occur, they may include:

• sore throat,
• throat discomfort,
• and redness.

Because throat gonorrhoea is frequently asymptomatic, laboratory testing may be needed to identify it.

Throat infection is also important in efforts to control antibiotic-resistant gonorrhoea.

Gonorrhoea of the Eye

Gonorrhoea can occasionally infect the eye.

Symptoms can include:

• redness,
• pain,
• swelling,
• and discharge.

Gonococcal eye infection can be serious and requires prompt medical assessment.

Avoid touching your eyes after contact with potentially infected genital secretions, and wash your hands appropriately.

How Soon Do Gonorrhoea Symptoms Appear?

When symptoms occur, they often develop within days after exposure.

WHO reports that symptoms commonly begin approximately 1–14 days after sexual contact with an infected person.

However, the absence of symptoms does not exclude infection.

Do not wait for symptoms before seeking testing if you know or suspect that you have been exposed.

How Is Gonorrhoea Diagnosed?

Gonorrhoea should ideally be diagnosed using appropriate laboratory testing.

A healthcare professional may collect:

• a urine sample,
• vaginal or cervical swab,
• urethral sample,
• rectal swab,
• or throat swab,

depending on the person's anatomy, symptoms and sites of sexual exposure.

A commonly used laboratory method is a nucleic acid amplification test (NAAT).

Why the Site of Testing Matters

A urine or genital test does not necessarily detect an infection located only in the throat or rectum.

For example, someone who has had oral or anal sexual exposure may require testing from those sites.

Discussing sexual exposure openly with an appropriate healthcare professional helps determine which samples should be collected.

Sexual-health professionals are accustomed to these conversations.

Should You Get Tested if You Have No Symptoms?

Yes, in some circumstances.

Testing can be appropriate if:

• a sexual partner has been diagnosed with gonorrhoea,
• you have had sexual contact that may have exposed you,
• you have another STI,
• you have new or multiple sexual partners,
• you belong to a group for whom local guidelines recommend regular screening,
• or a healthcare professional recommends testing based on your circumstances.

Screening recommendations vary by country and population.

Follow the guidance applicable where you live.

Gonorrhoea and Other STIs

Someone diagnosed with gonorrhoea may also have another sexually transmitted infection.

Depending on individual circumstances and local guidelines, healthcare professionals may recommend testing for infections such as:

• chlamydia,
• syphilis,
• and HIV.

Having one STI does not automatically mean that another is present, but overlapping risk factors make broader sexual-health assessment useful.

Can Gonorrhoea Be Cured?

Yes.

Gonorrhoea is a bacterial infection and can generally be cured with appropriate antibiotics.

However, treatment has become increasingly challenging because Neisseria gonorrhoeae has developed resistance to multiple antibiotics.

The exact medicine, dose and treatment strategy can differ between countries because resistance patterns vary.

For this reason, treatment should follow current local or national medical guidelines.

How Is Gonorrhoea Treated?

Current international guidance uses specific antibiotics that remain effective against gonorrhoea.

Ceftriaxone, given by injection, is widely used as a preferred treatment for uncomplicated gonorrhoea.

However, treatment recommendations can change as antibiotic resistance evolves.

Other treatment may be necessary when:

• ceftriaxone cannot be used,
• antibiotic resistance is suspected,
• treatment fails,
• another STI such as chlamydia has not been excluded,
• or the infection is complicated.

A healthcare professional should select the appropriate treatment.

Do Not Treat Gonorrhoea Yourself

Do not attempt to cure gonorrhoea using:

• leftover antibiotics,
• antibiotics purchased without appropriate medical guidance,
• someone else's medicine,
• herbal preparations,
• supplements,
• or home remedies.

Using an inappropriate antibiotic or dose may:

• fail to cure the infection,
• allow complications to develop,
• permit continued transmission,
• and contribute to antimicrobial resistance.

Completing treatment exactly as instructed is important.

Antibiotic-Resistant Gonorrhoea

Antimicrobial resistance is one of the most serious challenges in gonorrhoea control.

Over decades, Neisseria gonorrhoeae has developed resistance to several antibiotics previously used to treat it.

Resistance has affected medicines from multiple antibiotic classes.

Even resistance to some of the remaining effective treatments has been reported.

This is why:

• antibiotics should be used appropriately,
• current treatment guidelines matter,
• treatment failure should be investigated,
• and people should not self-medicate.

What if Symptoms Continue After Treatment?

Return to a healthcare professional if:

• symptoms do not improve,
• symptoms return,
• you develop new symptoms,
• or you believe you may have been exposed again.

Persistent symptoms can result from:

• reinfection,
• another infection,
• incomplete treatment,
• or antibiotic resistance.

Additional testing, including culture and antibiotic susceptibility testing, may sometimes be necessary.

Should Sexual Partners Be Told?

Yes.

Current or recent sexual partners may also have gonorrhoea without knowing it.

Partner notification allows them to:

• receive testing,
• receive treatment when appropriate,
• avoid complications,
• and reduce further transmission.

A sexual-health service may be able to help with confidential partner notification where such services are available.

When Can You Have Sex Again After Treatment?

People treated for gonorrhoea should follow their healthcare professional's instructions about when sexual activity can safely resume.

International guidance commonly recommends avoiding sexual activity for at least seven days after appropriate treatment and until relevant sexual partners have also been treated.

This helps prevent immediate reinfection and further transmission.

Can You Get Gonorrhoea Again?

Yes.

Having gonorrhoea once does not create reliable immunity.

A person can become infected again after successful treatment.

Reinfection commonly occurs when:

• an untreated partner still has the infection,
• a new sexual partner has gonorrhoea,
• or sexual exposure occurs before treatment has been completed appropriately.

Follow-up or repeat testing may therefore be recommended.

Complications in Women

Untreated gonorrhoea can spread from the cervix into the upper reproductive tract and contribute to pelvic inflammatory disease (PID).

PID can lead to:

• chronic pelvic pain,
• scarring of the fallopian tubes,
• difficulty becoming pregnant,
• and increased risk of ectopic pregnancy.

Some people develop these complications despite having had few or no obvious gonorrhoea symptoms.

Early diagnosis and treatment therefore matter.

Complications in Men

Untreated gonorrhoea can cause inflammation around structures connected to the testicles, including epididymitis.

Symptoms may include:

• testicular pain,
• tenderness,
• and swelling.

Rarely, complications can affect fertility.

Sudden or severe testicular pain requires prompt medical assessment because other urgent conditions can produce similar symptoms.

Disseminated Gonococcal Infection

In uncommon cases, gonorrhoea can spread through the bloodstream to other parts of the body.

This is called disseminated gonococcal infection (DGI).

Symptoms can include:

• fever,
• joint pain,
• swollen joints,
• tendon pain,
• and skin lesions or rash.

Serious infection can occasionally involve other organs.

Someone with suspected gonorrhoea who develops significant fever, severe joint symptoms or appears seriously unwell should seek urgent medical assessment.

Gonorrhoea and HIV

Gonorrhoea and other STIs can increase vulnerability to acquiring or transmitting HIV in certain circumstances.

People diagnosed with gonorrhoea may therefore be offered HIV testing.

Depending on individual risk, a healthcare professional may also discuss HIV-prevention options such as pre-exposure prophylaxis (PrEP) where available and appropriate.

Gonorrhoea During Pregnancy

Gonorrhoea during pregnancy requires appropriate diagnosis and treatment.

Untreated infection can cause complications and may be passed to a baby around the time of childbirth.

Pregnant people diagnosed with gonorrhoea should receive treatment appropriate for pregnancy and according to current medical guidelines.

Sexual partners should also receive appropriate assessment and management to reduce reinfection.

Gonorrhoea in Newborn Babies

A baby exposed to gonorrhoea around childbirth can develop a serious eye infection known as gonococcal ophthalmia neonatorum.

Symptoms can include:

• eye redness,
• swelling,
• pain,
• and discharge.

Without prompt treatment, serious eye damage can occur.

Gonococcal infection in newborns can also occasionally cause more widespread illness.

Prenatal STI screening according to local recommendations and prompt treatment of gonorrhoea during pregnancy are important methods of protecting both parent and baby.

How Can Gonorrhoea Be Prevented?

Gonorrhoea is preventable.

Risk can be reduced through several approaches.

Use condoms correctly and consistently

Correct and consistent use of condoms during vaginal and anal sex can substantially reduce transmission risk.

Barrier protection can also reduce risk during oral sexual activity.

Condoms must be used correctly from the beginning of relevant sexual contact.

Get tested when appropriate

Testing is particularly important for people with:

• symptoms,
• known exposure,
• a partner diagnosed with an STI,
• or circumstances for which screening is recommended.

Because gonorrhoea can be asymptomatic, waiting for symptoms alone can miss infections.

Talk with sexual partners

Discussing:

• STI testing,
• sexual-health history,
• condom use,
• and prevention

can help partners make informed decisions.

Reduce exposure

Having fewer sexual partners can reduce opportunities for exposure.

A mutually monogamous relationship in which both partners have been appropriately tested and do not have gonorrhoea also reduces risk.

Avoid sex until treatment is complete

If gonorrhoea is diagnosed, follow professional advice about abstaining from sexual activity after treatment and ensure partners receive appropriate care.

This reduces transmission and reinfection.

Does Washing After Sex Prevent Gonorrhoea?

No.

Washing the genitals, urinating after sex or douching does not reliably prevent gonorrhoea after exposure.

Douching is unnecessary and can disturb the normal vaginal environment.

Barrier protection, appropriate testing and treatment are far more important prevention measures.

Are Condoms 100% Effective?

No prevention method other than avoiding relevant sexual exposure eliminates every possibility of transmission.

However, correct and consistent condom use substantially reduces the risk of gonorrhoea and several other STIs.

Using condoms incorrectly or only partway through sexual contact reduces their protective benefit.

Is There a Gonorrhoea Vaccine?

There is currently no widely approved vaccine specifically used to prevent gonorrhoea.

Research into gonorrhoea vaccines continues.

Therefore, current prevention relies primarily on:

• safer sexual practices,
• barrier protection,
• testing,
• prompt treatment,
• and partner management.

When Should You Seek Medical Care?

Arrange testing or medical assessment if:

• you have burning or pain when urinating,
• you notice unusual penile or vaginal discharge,
• you have unexplained bleeding between periods,
• you develop rectal discharge, pain or bleeding,
• you have persistent throat symptoms after a relevant sexual exposure,
• a sexual partner has gonorrhoea,
• or you believe you may have been exposed to an STI.

Do not wait for symptoms if a partner tells you they have tested positive.

When Is Urgent Medical Care Needed?

Seek urgent medical care if you develop symptoms such as:

• severe pelvic or abdominal pain,
• severe testicular pain or swelling,
• high fever or serious illness,
• painful or swollen joints with fever or rash,
• severe eye pain or discharge,
• or significant illness during pregnancy.

These symptoms may indicate a complication or another condition requiring prompt assessment.

The Bottom Line

Gonorrhoea is a common bacterial sexually transmitted infection caused by Neisseria gonorrhoeae.

It can infect the:

• genitals,
• rectum,
• throat,
• and occasionally eyes.

Many infections cause no symptoms, especially in women and at throat or rectal sites.

When symptoms occur, they can include:

• pain or burning when urinating,
• penile or vaginal discharge,
• bleeding between periods,
• testicular pain,
• rectal symptoms,
• and sore throat.

Gonorrhoea can usually be cured with appropriate antibiotics, but antibiotic resistance is a growing global problem.

Untreated infection can cause complications including:

• pelvic inflammatory disease,
• fertility problems,
• pregnancy complications,
• epididymitis,
• and, rarely, infection spreading through the bloodstream.

Correct condom use, appropriate STI testing, prompt treatment and ensuring partners receive care can substantially reduce transmission.

Never attempt to treat suspected gonorrhoea with leftover or unprescribed antibiotics.
