Gonorrhea often causes no symptoms at all. Roughly 90% of women and up to 87% of men with a urogenital infection never notice anything wrong, which is why the infection spreads so easily. When symptoms do appear, they typically show up 1 to 14 days after sexual contact, and they vary depending on which part of the body is infected.
Symptoms in Men
When men do develop symptoms, the two hallmarks are a burning sensation when urinating and discharge from the penis. The discharge can be white, yellow, or green. Some men also notice swollen or tender testicles, though this is less common and usually signals that the infection has spread to the tubes behind the testicles.
Urethral symptoms tend to appear sooner in men than in women, often within two to five days of exposure. The discharge may start thin and become thicker over time. Because these signs overlap with other sexually transmitted infections like chlamydia, testing is necessary to confirm the cause.
Symptoms in Women
Women are far more likely to have no symptoms or to mistake early signs for something else, like a urinary tract infection or a yeast infection. When symptoms are present, they can include painful or burning urination, increased vaginal discharge that may look unusual in color or consistency, and vaginal bleeding between periods or after sex.
Lower abdominal or pelvic pain can develop if the infection moves beyond the cervix into the uterus or fallopian tubes. This progression, known as pelvic inflammatory disease, can cause fever, more intense pelvic pain, and pain during sex. Left untreated, it can lead to long-term fertility problems or chronic pain. Because so many women carry the infection without knowing it, routine screening is the most reliable way to catch it early.
Rectal and Throat Infections
Gonorrhea can infect the rectum through anal sex or, in women, by spreading from a nearby genital infection. Rectal symptoms include anal itching, soreness, discharge, and bleeding. Painful bowel movements are also possible. Many rectal infections, however, produce no symptoms at all.
Throat infections from oral sex are especially tricky because they rarely cause noticeable symptoms. When they do, you might notice a persistent sore throat, but it’s easily confused with a common cold or strep throat. Throat infections can also serve as a hidden reservoir, transmitting the bacteria to partners through oral sex even when you feel perfectly fine.
Eye Infections
Gonorrhea can infect the eyes if bacteria are transferred by hand from a genital site. This causes redness, swelling, pain, and a heavy discharge from one or both eyes. Without treatment, a gonococcal eye infection can damage the cornea and threaten vision. Newborns can also develop eye infections during delivery if the mother has an active infection, which is why hospitals routinely apply antibiotic eye drops to babies shortly after birth.
Disseminated Infection
In rare cases, the bacteria enter the bloodstream and spread to other parts of the body. This is called disseminated gonococcal infection, and it produces a distinctive set of symptoms: joint pain, redness, and swelling (often in the wrists, knees, or ankles), along with inflammation of the tendons. Small skin lesions, typically raised and pus-filled, may appear on the hands, fingers, or trunk. Fever and a general feeling of illness usually accompany these signs.
Disseminated infection is more likely when the original infection goes untreated for an extended period. It requires prompt medical treatment because it can permanently damage joints if allowed to progress.
Why So Many Cases Go Unnoticed
The high rate of asymptomatic infection is what makes gonorrhea particularly dangerous from a public health perspective. A person who feels completely healthy can carry and transmit the bacteria for weeks or months. This is true across all infection sites: genital, rectal, and throat.
If you’ve had unprotected sex with a new partner or a partner who has tested positive, getting tested is the only reliable way to know your status, regardless of whether you feel symptoms. The standard test is a nucleic acid amplification test, which works on a simple urine sample or a swab (vaginal, throat, or rectal depending on exposure). Results typically come back within a few days.
Antibiotic Resistance Is Changing Treatment
Gonorrhea has become increasingly difficult to treat. Between 2022 and 2024, resistance to the primary antibiotics used against it rose sharply. Resistance to one frontline drug jumped from 0.8% to 5%, and resistance to another climbed from 1.7% to 11%, with resistant strains detected in a growing number of countries. This trend matters for anyone diagnosed: follow-up testing after treatment is more important now than in the past to confirm the infection is actually gone. If symptoms persist after treatment, return for retesting rather than assuming the antibiotics worked.
