Chlamydia and gonorrhea symptoms

What are chlamydia and gonorrhea?

Chlamydia and gonorrhea are bacterial sexually transmitted infections (STIs). Both can infect the urethra, the tube that carries urine out of the body, and both can also affect the rectum and throat depending on sexual exposure.

Chlamydia is caused by Chlamydia trachomatis, while gonorrhea is caused by Neisseria gonorrhoeae. A man can have either infection without noticeable symptoms.

That is why waiting for obvious symptoms is not a reliable way to know whether you have an STI.

Doctar's STI testing guide covers testing for common sexually transmitted infections.

Chlamydia symptoms in men

Many men with chlamydia have no symptoms. When symptoms occur, they often involve the urethra.

Possible symptoms include:

• burning or pain while urinating

• clear, cloudy or whitish discharge from the penis

• irritation around the opening of the penis

• pain or swelling in one or both testicles

• rectal pain, discharge or bleeding when the rectum is infected

Symptoms may develop days or weeks after exposure, but timing varies. A man should not assume that the absence of symptoms means he is infection-free.

Gonorrhea symptoms in men

Gonorrhea can also be silent, but symptomatic urethral infection may be more noticeable.

Possible symptoms include:

• burning or painful urination

• white, yellow or green penile discharge

• increased discharge from the penis

• tenderness or swelling of a testicle

• rectal discomfort, discharge or bleeding

• sore throat when the throat is infected

Gonorrhea symptoms can sometimes be more sudden or pronounced than those of chlamydia, but there is too much overlap to diagnose either infection based on symptoms alone.

Chlamydia vs gonorrhea: what's the difference?

The symptoms can be remarkably similar.

A laboratory test is needed to determine which infection is present.

In clinical practice, men sometimes assume that thick discharge means gonorrhea and mild discharge means chlamydia. That is not a safe distinction. The symptoms overlap, and some men have both infections at the same time.

Burning while urinating

A burning sensation when passing urine is one of the symptoms that can bring men to a doctor.

It can occur with both chlamydia and gonorrhea when the urethra is infected. But burning urination has many other causes, including urinary tract infections, prostatitis and irritation.

Doctar's prostatitis symptoms and treatment guide explains another condition that can cause urinary burning and pelvic discomfort.

A urine or swab test is more useful than trying to identify the cause from the sensation alone.

Penile discharge

Discharge from the penis is a common sign of urethral infection.

With gonorrhea, discharge may be thick and yellow, white or green. Chlamydia can cause a clearer or less obvious discharge. But these descriptions are not diagnostic.

Some men have discharge that is barely noticeable, while others have none at all.

If you notice unexplained penile discharge, avoid self-treating with leftover antibiotics and arrange STI testing.

Doctar's penile irritation guide discusses other causes of penile irritation and genital symptoms.

Testicular pain or swelling

Chlamydia and gonorrhea can sometimes spread from the urethra to the epididymis, a structure next to the testicle that stores and carries sperm.

This can cause epididymitis, with pain and swelling that may develop on one side.

Testicular pain should not automatically be blamed on an STI. Sudden, severe testicular pain can be an emergency and needs immediate medical assessment.

If fertility is a concern, Doctar's male infertility causes guide explains some of the conditions that can affect male reproductive health.

Rectal symptoms

Men who have receptive anal sex can develop rectal chlamydia or gonorrhea.

Symptoms may include:

• rectal pain

• itching or irritation

• discharge

• bleeding

• painful bowel movements

Some rectal infections cause no symptoms at all.

This is why STI testing should be based on where sexual exposure occurred, not simply on a urine test.

Throat symptoms

Chlamydia and gonorrhea can infect the throat following oral sexual exposure.

A throat infection may cause a sore throat or swollen glands, but many people have no symptoms.

A routine throat swab is not necessary for everyone. A clinician may recommend it based on the type of sexual exposure and risk.

Doctar's oral STI guide provides additional information about infections affecting the mouth and throat.

Can you have both chlamydia and gonorrhea?

Yes.

Coinfection can occur, which is one reason healthcare professionals may test for both when evaluating urethral symptoms or a relevant sexual exposure.

Do not assume that a negative test for one infection rules out the other.

Testing should be selected according to the exposure and symptoms.

How are chlamydia and gonorrhea diagnosed?

Symptoms alone cannot confirm either infection.

Nucleic acid amplification tests (NAATs) are commonly used to detect chlamydia and gonorrhea. Depending on the site of infection, testing may involve:

• urine

• urethral specimens

• rectal swabs

• throat swabs

The correct sample depends on sexual exposure.

For example, a urine test may detect a urethral infection but will not necessarily detect an infection in the throat or rectum.

Doctar's male STI testing guide discusses accessible STI testing options.

When should men get tested?

Consider STI testing if:

• you develop penile discharge

• urination becomes painful or burns

• you develop unexplained genital symptoms

• a sexual partner tells you they have chlamydia or gonorrhea

• you have had condomless sex with a new or higher-risk partner

• you have multiple sexual partners

• you develop rectal symptoms after anal exposure

• you develop symptoms after oral sexual exposure

Testing may also be appropriate even when you feel completely well, depending on your sexual health risk.

Doctar's STI prevention guide discusses screening and ways to reduce future infection risk.

How soon after exposure should you test?

There is no single testing time that works for every STI and every test.

Testing too soon after exposure can produce a negative result before an infection becomes detectable. The appropriate timing depends on the infection, type of test and exposure.

If the exposure was recent and you are worried, speak with a healthcare professional rather than relying on an internet “one-size-fits-all” window period.

What happens if the test is positive?

Both chlamydia and gonorrhea are bacterial infections that can be treated with antibiotics.

However, the correct treatment depends on the infection, local antibiotic resistance patterns and individual circumstances. Gonorrhea is particularly important because antibiotic resistance has become a major public-health concern.

Do not take antibiotics without a confirmed or clinically suspected diagnosis and medical guidance.

Treatment also involves considering recent sexual partners to reduce reinfection and further transmission.

Doctar's partner treatment guide explains partner management for selected bacterial STIs.

Can untreated chlamydia or gonorrhea cause complications?

Yes.

Untreated infections can spread beyond the initial site.

In men, possible complications include:

• epididymitis

• testicular or scrotal pain

• reproductive complications

• persistent pelvic or genital symptoms

• rarely, infection spreading to other parts of the body

Gonorrhea can occasionally cause a serious disseminated infection involving joints, skin or other organs.

This is why symptoms should not simply be ignored because they seem mild.

Can chlamydia or gonorrhea affect fertility?

Untreated infections can contribute to reproductive complications, particularly when they spread to structures involved in sperm transport.

That does not mean that every man with chlamydia or gonorrhea will become infertile.

If conception has been difficult, a proper fertility evaluation is more appropriate than assuming an STI is responsible. Doctar's male fertility testing guide explains the evaluation process.

A semen analysis may be part of a fertility assessment.

Can chlamydia or gonorrhea cause erectile dysfunction?

Neither infection is considered a typical direct cause of erectile dysfunction.

Pain, anxiety, relationship stress and concerns about sexual health can affect sexual confidence, however.

If erection problems continue after an infection has been treated, other causes should be considered.

Doctar's erectile dysfunction guide explains the broader causes of ED.

Can condoms prevent chlamydia and gonorrhea?

Correct and consistent condom use can substantially reduce the risk of transmitting chlamydia and gonorrhea.

Unlike HPV and herpes, these infections are primarily spread through infected sexual fluids and mucosal contact, so condoms can provide significant protection when used properly.

Condoms do not eliminate risk completely.

Doctar's STI prevention guide covers safer-sex practices in more detail.

What should you do if your partner tests positive?

Take the result seriously even if you feel completely well.

A healthcare professional can advise whether you need testing, treatment or both. Depending on the infection and circumstances, recent partners may also need evaluation.

Avoid sexual contact until you have received appropriate medical advice and completed the recommended treatment period.

Do not rely on the absence of symptoms as proof that you are not infected.

When should you seek urgent medical care?

Seek prompt medical attention if STI symptoms are accompanied by:

• severe testicular pain or swelling

• fever or chills

• significant pelvic or abdominal pain

• rapidly worsening symptoms

• painful swollen joints or a spreading rash

Sudden severe testicular pain is particularly important because testicular torsion is an emergency and cannot be safely distinguished at home from other causes of scrotal pain.
