Gonorrhea symptoms in men usually show up as a thick white, yellow, or green discharge from the penis and a burning sensation when you urinate, sometimes with swollen or painful testicles. Symptoms tend to appear within days of exposure, but many infections, especially in the throat, cause nothing at all, so testing is the only way to be sure.
Common gonorrhea symptoms in men
Gonorrhea is caused by the bacterium Neisseria gonorrhoeae, which infects the lining of the urethra, rectum, and throat CDC. In men, a urethral infection is the most likely version to announce itself, and when it does, it's usually hard to ignore.

Penile discharge
The classic sign is discharge from the tip of the penis, white, yellow, or green. Gonorrheal discharge is often thicker and more purulent (pus-like) than the thin, watery discharge that chlamydia causes. It happens because the bacteria trigger inflammation in the urethra, and your immune system floods the area with white blood cells, which is what you're actually seeing.
Burning when you urinate
Burning or stinging during urination (dysuria) comes from the same inflamed urethral lining. Urine passing over irritated tissue produces a sharp, scalding feeling. Some men notice it most with the first urination of the day.
Swollen or painful testicles
Less commonly, the infection spreads up from the urethra to the epididymis, the coiled tube behind each testicle where sperm mature. That causes one testicle to become swollen, tender, and painful, sometimes with a dragging ache. The infection has moved beyond the urethra and needs prompt attention.
Throat and rectal gonorrhea in men
Gonorrhea isn't limited to the penis. If you've had receptive oral or anal sex, the bacteria can take hold in the throat or rectum, and these infections are frequently silent.
Pharyngeal (throat) gonorrhea is usually symptomless; the majority of throat infections cause no sore throat at all CDC STI guidelines. In the throat, gonorrhea can pick up resistance genes from harmless resident bacteria, and a silent throat infection can persist for weeks.
Rectal gonorrhea may produce discharge, anal itching, soreness, bleeding, or pain during bowel movements, though it too is often unnoticed. An infection at a site you don't test won't be found, so ask for swabs of every site you've been exposed at.
How soon do symptoms appear — and when they don't
When gonorrhea does cause urethral symptoms in men, they typically begin within a few days of exposure, faster on average than chlamydia. But "typically" hides a lot. Plenty of men have no symptoms whatsoever, and throat infections are symptomless far more often than not.
That gap between exposure and a reliable test result is real, and a test done too early can miss a true infection. If you've had a recent exposure, check the timing before booking. See the rundown on when to test after exposure.
Gonorrhea vs chlamydia discharge — how to tell
You can't diagnose yourself by looking, but there are patterns. Gonorrhea discharge tends to be thicker, more abundant, and yellow-green, with sharper burning. Chlamydia discharge is more often thin, clear or cloudy, with milder symptoms when there are any at all. The two infections frequently travel together, so testing and treatment plans account for both.
| Gonorrhea | Chlamydia | |
|---|---|---|
| Discharge | Thicker, white/yellow/green, pus-like | Thinner, clear or cloudy, often scant |
| Burning | Often pronounced | Milder or absent |
| Onset | Usually within days | Often slower, frequently silent |
| Symptom-free? | Common, especially in the throat | Very common |
Because the overlap is so large, the symptom picture alone won't tell you which one you have. For a full side-by-side, see gonorrhea vs chlamydia. And if you're comparing what this looks like across sexes, here's gonorrhea symptoms in women, where infections are far more often asymptomatic.
Emergency signs you shouldn't ignore
Most gonorrhea is uncomplicated, but two situations need urgent care.
- Epididymitis — a swollen, painful testicle, usually on one side. This is inflammation of the epididymis (the tube behind the testicle), and delaying care can affect fertility. Don't ride it out at home.
- Disseminated gonococcal infection (DGI) — when the bacteria spread into the bloodstream and joints, causing fever, joint pain or swelling, and skin lesions. DGI can be life-threatening and is managed differently from routine gonorrhea, typically with hospitalization and intravenous antibiotics CDC.
How men get tested
The preferred test is a NAAT (nucleic acid amplification test), which detects the bacteria's genetic material with high accuracy — sensitivity usually above 90% and specificity around 99%. For a urethral infection, you give a first-catch urine sample (the first part of your stream). If you've had oral or anal sex, you add a quick throat or rectal swab; patient-collected swabs are acceptable.
The most common testing mistake men make is sampling only urine when their exposure was oral or anal, which misses throat and rectal infections entirely. Speak up about every site. When you're ready, you can get tested.
Treatment: the ceftriaxone shot, and why pills aren't enough
Gonorrhea is curable, but medicine can't reverse damage that's already happened, so prompt treatment matters. The current first-line treatment is a single ceftriaxone injection given in the clinic MMWR, 2020. It's an intramuscular shot, not a take-home pill.
In 2020, CDC moved from dual therapy (ceftriaxone plus azithromycin) to ceftriaxone alone, and raised the dose. The reason was resistance: isolates with elevated azithromycin susceptibility climbed from 0.6% in 2013 to 4.6% in 2018, so azithromycin was dropped while gonorrhea remains highly susceptible to ceftriaxone Clin Infect Dis, 2020. If chlamydia hasn't been ruled out, a short course of doxycycline pills is added on top of the shot.
Oral-only antibiotics are no longer reliable for gonorrhea, so the injection is standard. Throat infections are harder to cure than genital ones — even fully susceptible pharyngeal infections fail treatment a small but real share of the time — so a test-of-cure is advised after throat treatment treatment-failure review. After treatment, abstain from sex for a week, make sure recent partners get treated, and plan to retest in a few months to catch reinfection. Full regimens, allergy alternatives, and partner options are covered in gonorrhea treatment.
Complications if it's left untreated
Untreated gonorrhea in men can lead to epididymitis (inflammation behind the testicle that can affect fertility) and, less often, the spread of bacteria to the blood and joints as DGI. The infection can also be passed to partners and, in women, cause pelvic inflammatory disease, fallopian-tube scarring, ectopic pregnancy, and infertility. Resistance trends add weight to treating promptly: a ceftriaxone-resistant strain has already spread internationally, and the WHO estimated 82 million new gonorrhea infections globally in 2020 WHO.
For perspective on how common this is in the US, reported gonorrhea has actually been falling — about 601,000 cases in 2023 — though rates vary enormously by location CDC AtlasPlus, 2023.
When to see a clinician
See a clinician if you notice penile discharge, burning when you urinate, or testicle pain, or if a partner tells you they tested positive even when you feel fine. A swollen, painful testicle warrants same-day attention. If you've had an exposure but have no symptoms, you still need testing, because silent infections are common and only a test will find them.
