Gonorrhea in men most commonly shows up as a noticeable discharge from the tip of the penis, ranging in color from white to yellow to green. The discharge often has a thick, pus-like consistency and may leave visible stains on underwear. Along with the discharge, you might notice redness or swelling at the opening of the penis. About 80% of men with urethral gonorrhea develop these classic visible symptoms, while roughly 6% show no signs at all.
What the Discharge Looks Like
The hallmark sign is a discharge that appears at the tip of the penis, sometimes accumulating visibly at the urethral opening. It can range from a thin, whitish fluid to a thicker, yellowish-green material that looks like pus. In many cases the discharge is heavy enough to notice on its own, staining underwear or appearing without squeezing the penis. Some men first spot it in the morning, when fluid has collected overnight.
The color and thickness can vary depending on how far the infection has progressed. Early on, the discharge may appear clear or slightly milky. Within a day or two it typically becomes more opaque, shifting toward yellow or green, and takes on a thicker consistency. The opening of the penis may also appear red, irritated, or slightly swollen.
Pain and Burning During Urination
Most men with gonorrhea describe a burning or stinging sensation when they urinate. The discomfort can start at the very beginning of urination or linger afterward. Some men feel a persistent soreness or itching inside the urethra between bathroom trips. This burning is often what drives someone to look more closely and notice the discharge for the first time.
When Symptoms Appear
Symptoms typically show up within two to five days after exposure, though it can take up to two weeks. The timeline matters because if you’re checking yourself after a recent encounter, you may not see anything for several days even if you’ve been infected. The infection is contagious during this window regardless of whether visible signs have appeared yet.
Testicular Swelling
In a smaller number of cases, the infection travels deeper and causes swelling and pain in one or both testicles. This condition, called epididymitis, involves inflammation of the coiled tube behind the testicle where sperm is stored. It usually affects one side and causes tenderness, noticeable swelling, and sometimes warmth in the scrotum. The swelling can develop gradually over several days. Left untreated, it can spread to the testicle itself. This is less common than discharge and burning, but it’s a sign the infection has progressed and needs prompt treatment.
Throat and Rectal Infections
Gonorrhea doesn’t only affect the penis. Men who contract the infection in the throat typically have no visible symptoms, though some develop a persistent sore throat or redness in the back of the mouth. Rectal gonorrhea can cause discharge from the anus, itching, soreness, and occasionally bleeding. These infections are easy to miss because the symptoms are mild or absent, and they won’t show up on a standard urine test. Specific swab testing is needed for each site.
How It Differs From Chlamydia
Chlamydia and gonorrhea overlap so much in appearance that even clinicians can’t reliably tell them apart by sight alone. Both can cause urethral discharge and burning during urination. That said, gonorrhea tends to produce heavier, more pus-like discharge with a more obvious color (yellow or green), while chlamydia discharge is often thinner, clearer, and less abundant. Gonorrhea symptoms also tend to appear sooner, within days rather than the one to three weeks chlamydia often takes.
The two infections frequently occur together. Because their symptoms are so similar, testing for both at the same time is standard practice. A positive result for one doesn’t rule out the other.
Men Who Show No Symptoms
About 6% of men with urethral gonorrhea have no symptoms at all at the time of diagnosis. Another roughly 14% report only mild or atypical symptoms, like slight irritation without obvious discharge. These men can still spread the infection to partners. If you’ve been exposed to someone with gonorrhea, the absence of visible signs doesn’t mean you’re in the clear. Testing is the only reliable way to know.
How It’s Treated
Gonorrhea is treated with a single antibiotic injection. Because chlamydia co-infection is common, you may also be given a week-long course of oral antibiotics to cover both. Symptoms usually start improving within a day or two of treatment, though you should avoid sexual contact for at least seven days after. A follow-up test three months later is recommended because reinfection rates run between 7% and 12% in the year after treatment.
