The most common gonorrhea symptoms in men are a thick yellow or green discharge from the penis and a burning pain when you urinate, usually appearing 2 to 5 days after exposure. But up to 1 in 10 infected men have no symptoms at all.
If that line made your stomach drop, take a breath. As a practising andrologist in Chennai, here’s the honest answer: gonorrhea is one of the most curable infections I treat. The fear is worse than the disease, provided you act early and get the correct treatment. This guide walks you through every symptom, the right test, and the exact, up-to-date antibiotic dose — including a dangerous mistake about dosing that I still see on Indian websites and on pharmacy counters every single week.
Quick Facts
- Gonorrhea is caused by the bacterium Neisseria gonorrhoeae; it spreads through vaginal, anal and oral sex, and from mother to baby at birth.
- In men, the classic signs are yellow/green penile discharge and burning urination, usually showing in 2–5 days (range about 2–8 days).
- Up to 10–15% of men — and even more women — have NO symptoms. Silent carriage is common, especially in the throat and rectum.
- It does NOT clear on its own, but it IS curable with the right antibiotic.
- The correct treatment is ceftriaxone 500 mg IM as a single dose (CDC 2021 STI Treatment Guidelines) — NOT the old 250 mg that many pages still quote.
Everything that matters, in 60 seconds
The essentials an andrologist wants every man to know — what it is, what it does, and why it is completely curable when caught.
How it spreads
Through vaginal, anal and oral sex, and from mother to baby at birth. Not from toilet seats, towels or pools. Symptoms appear fast — usually 2–5 days after exposure in men.
The first sign
A thick yellow or green discharge from the tip of the penis and a burning pain when you urinate. But up to 1 in 10 infected men feel nothing at all.
It hides at other sites
Throat and rectal infections are usually silent — the throat is symptomless about 90% of the time. Test every site that has been exposed, not only the one that hurts.
If left untreated
It does not clear on its own. It can climb to the epididymis and scar the sperm tube, threatening fertility, and rarely spread to blood, joints and heart (DGI).
The cure
One correct injection: ceftriaxone 500 mg IM as a single dose (CDC 2021) — not the outdated 250 mg. Doxycycline is added only to cover chlamydia.
How it is diagnosed
A NAAT on a first-catch urine sample or swab — the same sample also tests for chlamydia — and in a symptomatic man a Gram stain confirms it on the spot.
What is gonorrhea?
Gonorrhea is a bacterial sexually transmitted infection caused by Neisseria gonorrhoeae. It is one of the most common bacterial STIs in the world, with an estimated 82 million new infections every year globally (van Hal, 2026). The bacterium loves warm, moist surfaces — the urethra, the cervix, the rectum, the throat and even the eyes — which is exactly why the symptoms turn up in so many different places.
It is passed on through vaginal, anal and oral sex with an infected partner, and a mother can pass it to her baby during delivery. You cannot catch it from toilet seats, towels or swimming pools — that old fear, which I hear in clinic almost daily, is simply not how this germ travels.
Gonorrhea symptoms in men
This is the part most men come to me worried about, so let me be direct. In men, gonorrhea usually announces itself loudly, and the two cardinal signs are discharge and a burning sensation when passing urine.
Penile discharge and burning urination
The hallmark gonorrhea symptom in men is a thick discharge from the tip of the penis — often described as yellow, green, or sometimes white and cloudy. Alongside it comes dysuria, the burning or stinging pain when you urinate. Many men also notice the urge to pass urine more often. In symptomatic male urethritis, this discharge is so characteristic that a simple Gram stain of it can support the diagnosis on the spot (Yang, 2024).
If you are seeing pus-like discharge and feeling that burn, please do not wait it out and please do not buy a random strip of tablets. Get tested.
Swollen, painful testicle (epididymitis) — the andrology red flag
When gonorrhea is ignored, the infection can climb backwards from the urethra into the epididymis, the coiled tube behind each testicle that stores and transports sperm. This is epididymitis, and it shows up as a gradually worsening, one-sided ache and swelling in the scrotum, sometimes with fever. In sexually active men aged 14 to 35, Neisseria gonorrhoeae and Chlamydia trachomatis are the leading causes (McConaghy, 2017).
I flag this loudly because untreated epididymitis can scar that delicate tube and quietly damage fertility (McConaghy, 2017). This is the andrology angle nobody on the pharmacy counter tells you about.
Asymptomatic gonorrhea (silent carriage)
Here is the uncomfortable truth: not everyone gets the dramatic discharge. A meaningful share of infected men — often quoted around 10–15% — carry the bacterium with no symptoms at all, and silent, asymptomatic genital tract infections are easily passed to a partner without either person knowing (Solomon, 2017). People often ask me whether gonorrhea can “lay dormant for years.” It does not truly hibernate, but it can sit quietly causing low-grade damage and remaining transmissible, which is precisely why testing — not symptoms — is the only reliable way to know.
Gonorrhea symptoms at other sites: rectum, throat and eyes
Gonorrhea is not only a “penis problem.” Because it is spread by oral and anal sex too, it sets up shop wherever there is contact — and at these sites it is far more likely to be silent.
In a large pooled analysis, N. gonorrhoeae was found in the anorectal and oropharyngeal sites of men who have sex with men at rates comparable to or exceeding urogenital infection, much of it without symptoms (Harfouche, 2026). Rectal gonorrhea may cause anal discharge, itching, soreness or pain, but more than half of cases are silent. Pharyngeal (throat) gonorrhea is asymptomatic in roughly 90% of cases — you simply will not feel it, which is why I swab the throat when the history calls for it. Gonococcal conjunctivitis causes a red, sticky, pus-filled eye and needs urgent attention. The lesson is simple: test every site that has been exposed, not just the one that hurts.
Gonorrhea symptoms in women (brief)
In women, gonorrhea is often mild or completely silent, which is one reason it spreads so efficiently. When symptoms do appear, they include an unusual vaginal discharge, bleeding between periods, and lower pelvic or abdominal pain. The real danger is pelvic inflammatory disease (PID), which can scar the fallopian tubes and lead to tubal-factor infertility and ectopic pregnancy. If your partner has been diagnosed, she needs testing and treatment too — more on that below, and you can read our companion pages on related infections via the links at the end.
How long do gonorrhea symptoms take to show? (incubation)
This is one of the most-searched questions, and it is also where a lot of older Indian pages — including the previous version of this very page — went wrong by quoting chlamydia’s timeline instead.
Let me state it cleanly for gonorrhea specifically: symptoms typically appear 2 to 8 days after exposure, most often around 2 to 5 days in men. That is meaningfully faster than chlamydia, which tends to surface over one to three weeks (or not at all). And remember the caveat from above — a proportion of people never develop symptoms, so the absence of a burn or a discharge is not proof you are in the clear.
Can gonorrhea go away on its own? Is it curable?
Two questions, two clear answers.
Can it go away on its own? No. Gonorrhea does not self-cure. Symptoms may wax and wane and even seem to settle, but the bacteria persist, and they keep doing damage — climbing to the epididymis in men, or to the tubes in women. Untreated, it can even disseminate through the bloodstream into joints and, rarely, the lining of the heart and lungs (Togo, 2026).
Is it curable? Yes — completely. With the correct single antibiotic dose, gonorrhea is cured. The catch is the words correct and single. What worries me as a clinician is the Practo-style pattern I see constantly: men self-medicating with a leftover strip of cefixime or azithromycin “to get rid of it fast,” feeling better, and assuming they are cured when they are not. Please do not do this — it is both ineffective and, as you will see, dangerous for everyone.
Gonorrhea vs chlamydia: what’s the difference?
Patients constantly ask me, “How do I know if it’s gonorrhea or chlamydia?” They are different bacteria with overlapping symptoms, they frequently travel together, and — helpfully — the same test screens for both.
| Gonorrhea | Chlamydia | |
|---|---|---|
| Bacterium | Neisseria gonorrhoeae | Chlamydia trachomatis |
| Discharge | Thicker, yellow/green | White, watery/thin |
| Symptom onset | ~2–5 days (men) | ~1–3 weeks (often later) |
| Asymptomatic | Common (esp. throat/rectum) | Very common |
| Test | NAAT (same sample tests both) | NAAT |
| First-line Rx | Ceftriaxone 500 mg IM *(per CDC 2021 STI Treatment Guidelines)* | Doxycycline 100 mg BID ×7d |
Because co-infection is so common, treatment for gonorrhea is often designed to cover chlamydia as well, as you will see in the treatment section.
How is gonorrhea diagnosed?
The modern, gold-standard test is the NAAT (nucleic acid amplification test), also called a PCR — performed on a first-catch urine sample or a swab — and it is the most sensitive and specific method we have (Yang, 2024). Its great advantage is that the same sample tests for chlamydia at the same time, which matters because the two co-infect so often. In a symptomatic man, a urethral Gram stain is a quick, useful bedside confirmation (Yang, 2024).
In my clinical practice, I very frequently see men who were “tested” for gonorrhoea and chlamydia using antigen or antibody assays — the IgG and IgM blood tests. Please be careful here: for these two infections, antibody tests are unreliable. They throw up both false positives (a positive IgG can simply reflect an old, long-cleared exposure) and false negatives (early infection, before antibodies have risen), and they cannot separate an active infection from a past one. I have watched men be wrongly reassured, and others wrongly alarmed, by these reports. Stick to the PCR/NAAT. Yes, it costs a little more — but for its high sensitivity and specificity it is worth every rupee (Yang, 2024). A correct diagnosis is far cheaper than treating the wrong thing.
Because gonorrhoea and chlamydia spread readily through oral and anal sex, I swab every site that has been exposed — the throat and rectum as well as the urethra — not just the part that hurts; remember, these throat and rectal infections are usually silent (Harfouche, 2026). This oro-genital route is easy to underestimate: a symptomless throat infection picked up or passed on during oral sex is one of the commonest ways gonorrhoea quietly circulates.
Gonorrhoea also rarely travels alone. Because STIs cluster, at the same visit I routinely co-test for the infections that keep it company — our pages on chlamydia, syphilis, genital herpes and HIV each explain what to look for. Co-infection is the rule, not the exception, and gonorrhoea notably raises the risk of both catching and transmitting HIV. This clustering is especially pronounced in men who have sex with men (MSM), among whom gonorrhoea — particularly at the throat and rectum — is carried at substantially higher rates, frequently without any symptoms (Harfouche, 2026).
Where antibiotic resistance is suspected or a previous treatment has failed, we add a culture so the laboratory can test which antibiotics the strain is still sensitive to.
Gonorrhea treatment (the correct CDC 2021 dose)
Now the most important section — and the one where the old page carried a genuinely dangerous error.
The correct, current treatment for uncomplicated gonorrhea is ceftriaxone 500 mg intramuscularly (IM) as a single dose (Yang, 2024; Quilter, 2024). For anyone weighing 150 kg or more, the dose is 1 g IM.
If chlamydia co-infection has not been ruled out, we add doxycycline 100 mg orally twice daily for 7 days (Yang, 2024). That doxycycline is there to cover chlamydia — not as an “extra” gonorrhea drug.
A few critical corrections that this page must make plainly:
- The old “250 mg ceftriaxone” advice is outdated and wrong. The CDC raised the dose to 500 mg in its 2020 update, carried into the 2021 STI Treatment Guidelines — and it did so specifically because of rising resistance (Quilter, 2024). If you see 250 mg quoted anywhere, treat it as out of date.
- The old azithromycin dual-therapy regimen is no longer recommended. Adding azithromycin 1 g routinely to ceftriaxone has been dropped because of azithromycin resistance. Doxycycline replaces it only to cover chlamydia, only when chlamydia is not excluded.
- Cefixime is an alternative, not first-line. Oral cefixime is reserved for situations where ceftriaxone is genuinely unavailable, and it is inferior — particularly for throat infection. It is not a co-equal first option, and it is certainly not something to self-prescribe.
Partner treatment
Treating you alone is only half the job. Every sexual partner from the last 60 days must be tested and treated, or you will simply bounce the infection back and forth. After single-dose treatment, abstain from sex for 7 days and until all partners have completed treatment.
Test of cure and retesting
For most urogenital infections, a routine “test of cure” is not needed. But for pharyngeal (throat) gonorrhea, a test of cure is recommended about 7–14 days after treatment, because throat infections are harder to clear. And critically, everyone should be retested at 3 months, because reinfection rates are high (Yang, 2024). I build this follow-up into every gonorrhea consultation — clearance is not assumed, it is confirmed.
Antibiotic resistance and “super gonorrhea”
This is the single most important thing competitors leave out, so let me give it the space it deserves.
Gonorrhea has, one by one, defeated nearly every antibiotic we have thrown at it — and ceftriaxone is now essentially the last highly effective recommended drug we have (Quilter, 2024). That is exactly why the dose was raised from 250 mg to 500 mg: to stay ahead of a moving target.
The threat is not theoretical. Ceftriaxone-resistant strains carrying a mosaic penA resistance gene are now being detected across the globe, with cases frequently linked to acquisition in the Asia-Pacific region — and surveillance experts believe the true number is being under-reported because testing systems are patchy (van Hal, 2026). This is what the press calls “super gonorrhea.”
The research community is racing to respond. Promising new oral agents are in late-stage trials — zoliflodacin proved non-inferior to standard injectable therapy in a large phase 3 study (Luckey, 2026), and oral gepotidacin did the same in the EAGLE-1 trial (Ross, 2025). On the prevention side, doxycycline post-exposure prophylaxis (doxy-PEP) reduces bacterial STIs, though its effect on gonorrhea specifically is more modest and varies by region (Zhao, 2026). These are hopeful, but they are not licensed front-line treatment for you to buy today.
Here is my plea as a clinician: every time someone self-treats gonorrhea with a half-dose of leftover cefixime or azithromycin, they are quietly training the bacterium to resist our drugs. Self-medication is exactly how super gonorrhea is bred. Use the right drug, at the right dose, once — under supervision.
A note from my clinic (what I actually see)
In my clinic, I see this every week. The men I worry about most aren’t those with obvious discharge — those get diagnosed and cured. They are the ones who had a mild burning, bought a strip of azithromycin or cefixime from a pharmacy, felt better, and assumed they were cured. They weren’t. The infection quietly climbed to the epididymis, and months later they are sitting in my fertility clinic with a blocked, scarred tube and an abnormal semen analysis. Genital tract infections, Neisseria gonorrhoeae historically among the most important, are a recognised and treatable contributor to male infertility (Vives Suñé, 2026). Gonorrhea is curable in a single correct injection — but only if it’s the right drug at the right dose, your partner is treated, and you come back for your test of cure.
Complications of untreated gonorrhea
Epididymitis and male infertility
As covered above, untreated urethral gonorrhea can ascend to cause epididymitis, and because recognition and prompt therapy prevent scarring, delay is the enemy of fertility (McConaghy, 2017). Treating proven genital-tract infection is one of the few directly reversible factors we can act on in a sub-fertile man (Vives Suñé, 2026).
Disseminated gonococcal infection (DGI)
Rarely, the bacterium escapes into the bloodstream, causing fever, skin lesions and painful joints — and, in unusual cases, inflammation of the lining of the heart and lungs requiring intravenous treatment (Togo, 2026). DGI is a powerful reminder that this is not “just” a local nuisance.
Other risks
Untreated gonorrhea increases the risk of acquiring and transmitting HIV. In women it drives PID, infertility and ectopic pregnancy, and a baby infected at birth can develop sight-threatening eye infection (ophthalmia neonatorum).
How to prevent gonorrhea
Prevention is refreshingly straightforward: use condoms consistently, reduce the number of partners, and get regular STI screening if you are sexually active — remembering that screening, not symptoms, is what catches the silent infections (Harfouche, 2026). If you are diagnosed, ensure your partner is treated, and do not resume sex until you have both completed treatment. For higher-risk individuals, doxy-PEP is an emerging tool to discuss with a clinician (Zhao, 2026), but it is not a substitute for condoms or testing.
When to see a doctor or andrologist
See a doctor promptly if you have penile discharge, burning urination, or testicular pain or swelling, or if a partner has been diagnosed with gonorrhea or chlamydia — even if you feel completely well. The andrology angle matters here: catching and curing gonorrhea early is one of the simplest ways to protect your future fertility. Don’t sit with worry, and don’t sit with a pharmacy strip. Get tested, get the right injection, and get on with your life.

Frequently Asked Questions
What are the first signs of gonorrhea in a man?
Usually a thick yellow or green discharge from the tip of the penis and a burning sensation when you urinate, appearing within a few days of exposure.
How long does it take for gonorrhea symptoms to show?
Typically 2 to 5 days in men, with an overall range of about 2 to 8 days. Some people develop no symptoms at all.
Can you have gonorrhea with no symptoms?
Yes. Up to 10–15% of infected men, and even more women, have no symptoms, and throat and rectal infections are silent most of the time (Harfouche, 2026). This is exactly why testing matters more than how you feel.
Can gonorrhea go away on its own?
No. It does not self-clear. Symptoms may come and go, but the bacteria persist and can cause epididymitis and infertility if left untreated.
Is gonorrhea curable?
Yes — completely, with the correct single antibiotic dose given under medical supervision.
What is the correct treatment for gonorrhea?
Ceftriaxone 500 mg as a single intramuscular injection (1 g if you weigh 150 kg or more), per the CDC 2021 guidelines (Yang, 2024; Quilter, 2024). Doxycycline 100 mg twice daily for 7 days is added only if chlamydia has not been ruled out.
Is a 250 mg ceftriaxone injection enough for gonorrhea?
No. The CDC raised the recommended dose to 500 mg IM in its 2020/2021 update, specifically because of rising antibiotic resistance (Quilter, 2024). A 250 mg dose is outdated.
Can I just take cefixime or azithromycin tablets for gonorrhea?
Not as self-treatment. Ceftriaxone injection is first-line; cefixime is only an inferior alternative when ceftriaxone is unavailable, and routine azithromycin has been dropped because of resistance (Quilter, 2024). Self-medicating helps breed resistant “super gonorrhea.” See a doctor.
What’s the difference between gonorrhea and chlamydia?
They are different bacteria with overlapping symptoms. Gonorrhea discharge is typically thicker and yellow-green; chlamydia tends to be milder and slower to appear. They often co-infect and are detected by the same NAAT test.
Can gonorrhea affect my fertility?
Yes. Untreated, it can cause epididymitis and scar the tube that transports sperm, which is a recognised and treatable cause of male infertility (McConaghy, 2017; Vives Suñé, 2026).
Do I need a test after treatment?
Throat (pharyngeal) infections need a test of cure about 7–14 days after treatment, and everyone should be retested at 3 months because reinfection is common (Yang, 2024).
Does my partner need treatment too?
Yes. All sexual partners from the last 60 days must be tested and treated, or you will keep reinfecting each other. Abstain from sex for 7 days after treatment and until your partner is treated.
