Thick white, yellow or green penile discharge can be a strong clue in symptomatic men, but it is not diagnostic and some people have no discharge. This guide explains gonorrhea symptoms, the names you may hear, and how testing can clarify overlapping signs. Gonorrhea (US spelling), gonorrhoea (UK spelling), gonococcal infection; informally called “the clap”.
What causes gonorrhea?
Neisseria gonorrhoeae is a bacterium. It is also known as gonococcal infection; “the clap”; NG. A laboratory result should be interpreted in context: detecting an organism does not always mean it is causing the current symptoms.
| Cause | Neisseria gonorrhoeae |
|---|---|
| How it spreads / is acquired | vaginal, anal or oral sex and during childbirth |
| When symptoms may appear | Symptoms can begin within days, but timing varies and infection is frequently silent, especially in women and at throat or rectal sites. |
| Useful distinguishing clue | Thick white, yellow or green penile discharge can be a strong clue in symptomatic men, but it is not diagnostic and some people have no discharge. |
| Common symptom overlap | chlamydia, trichomoniasis, urethritis, cervicitis, UTI, vaginitis and proctitis |
Symptoms: common does not mean specific
Possible findings include burning urination, increased vaginal discharge, bleeding between periods, penile discharge, testicular discomfort, or rectal pain/discharge/bleeding. None of these, alone, confirms gonorrhea. Symptoms may be absent, may appear later than expected, or may improve while the infection or underlying problem remains.
What can look similar?
The differential diagnosis includes chlamydia, trichomoniasis, urethritis, cervicitis, UTI, vaginitis and proctitis. Coinfection is also possible, which is why a clinician may recommend more than one target or more than one sample site.
How is it diagnosed?
molecular testing (such as PCR) is commonly used on urine or site-specific swabs. Throat and rectal exposures require samples from those sites; urine alone can miss them. Culture is important when treatment failure or antimicrobial resistance is suspected.
When should you see a doctor promptly?
- Severe pelvic, abdominal or testicular pain
- Fever, faintness, rapidly worsening symptoms or pregnancy
- A new genital ulcer, blister or widespread rash
- Symptoms after sexual assault, or possible exposure to HIV
Questions readers ask
Why is gonorrhea sometimes missed in women?
It may have no symptoms or resemble a bladder or vaginal infection.
Can gonorrhea affect the throat or rectum?
Yes. Exposure at those sites can require separate swabs.
