What Is Gonorrhea?
Gonorrhea is a common sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. It can infect the genitals, rectum, and throat. In the United States, gonorrhea is the second most commonly reported STI, with over 600,000 cases reported each year. It affects people of all ages but is most common in young adults aged 15–24.
How Is Gonorrhea Spread?
Gonorrhea is transmitted through sexual contact, including vaginal sex, anal sex, and oral sex (giving or receiving). You can get gonorrhea even without full intercourse — any contact between the mouth, genitals, or rectum can transmit the infection. A pregnant person can also pass gonorrhea to their baby during childbirth.
Oral Gonorrhea vs. Genital Gonorrhea
While caused by the same bacterium, oral (pharyngeal) and genital gonorrhea differ in important ways:
| Oral (Throat) Gonorrhea | Genital Gonorrhea | |
| How you get it | Giving or receiving oral sex with an infected partner | Vaginal or anal sex with an infected partner |
| Symptoms | Usually none — most people have no symptoms at all | Men: burning with urination, discharge from the penis. Women: often no symptoms, but may have vaginal discharge, bleeding between periods, or pelvic pain |
| How often symptoms occur | Over half of cases have zero symptoms | About 90% of men have symptoms; up to 50–80% of women may have none |
| How it’s tested | Throat swab (NAAT test) | Urine test or genital swab (NAAT test) |
| Can it spread? | Yes — through oral sex, or rarely kissing | Yes — through vaginal, anal, or oral sex |
| Treatment note | May clear on its own over weeks to months, but treatment is still recommended to prevent spread and resistance | Requires treatment; can cause serious complications if untreated |
Why Oral Gonorrhea Matters
Because oral gonorrhea rarely causes symptoms, most people who have it don’t know. This means:
- It can be unknowingly passed to sexual partners.
- It is often missed unless specifically tested for.
- Routine STI screening typically does not include a throat swab unless you tell your provider about oral sex exposure.
- The throat may serve as a reservoir where the gonorrhea bacterium can develop antibiotic resistance.
Symptoms to Watch For
Genital gonorrhea
- Painful or burning urination
- Unusual discharge from the penis or vagina
- Pain or swelling in the testicles (men)
- Pelvic pain or bleeding between periods (women)
Oral gonorrhea
- Most people have no symptoms
- Occasionally: sore throat, redness in the back of the throat, or swollen lymph nodes in the neck
Rectal gonorrhea
- Often no symptoms
- May cause discharge, itching, soreness, or bleeding
When to Get Tested
Consider getting tested for gonorrhea if you:
- Have a new sexual partner or multiple partners
- Have had unprotected oral, vaginal, or anal sex
- Have been told a partner has gonorrhea or another STI
- Are experiencing any of the symptoms listed above
- Are a sexually active man who has sex with men (routine screening is recommended at all exposed sites)
Important: tell your healthcare provider about oral and anal sex so they can test the right sites. A urine test alone will not detect oral or rectal gonorrhea.
How Is Gonorrhea Treated?
Current treatment for uncomplicated gonorrhea is a single injection of the antibiotic ceftriaxone (500 mg). This treats infections at all body sites, including the throat, genitals, and rectum. Important points about treatment:
- Both you and your sexual partner(s) need to be treated.
- Avoid sexual contact for 7 days after treatment.
- If your symptoms don’t improve, return to your provider — antibiotic-resistant gonorrhea is a growing concern.
- A follow-up test (a ‘test of cure’) is recommended 7–14 days after treatment for throat infections, as these can be harder to cure than genital infections.
What Happens If Gonorrhea Is Not Treated?
- In women: Pelvic inflammatory disease (PID), which can cause chronic pelvic pain, damage to the fallopian tubes, and infertility.
- In men: Epididymitis (painful swelling near the testicles), which can rarely lead to infertility.
- In anyone: The infection can spread to the blood or joints (disseminated gonococcal infection), a medical emergency.
- During pregnancy: Untreated gonorrhea can be passed to the baby during delivery, potentially causing a serious eye infection.
How to Protect Yourself
- Use condoms or dental dams during vaginal, anal, and oral sex.
- Limit the number of sexual partners.
- Get tested regularly, especially with new or multiple partners.
- Talk openly with your partner(s) about STI testing and status.
- Ask about Doxy-PEP, a dose of doxycycline after sex that can reduce the risk of bacterial STIs including some gonorrhea infections. [link: /doxy-prep/]
- If prescribed treatment, take it exactly as directed and make sure your partner is treated too.
The Bottom Line
Gonorrhea is a very common and treatable infection, but it can cause serious problems if left untreated. Oral gonorrhea is especially easy to miss because it almost never causes symptoms — the only way to know is to get tested. If you are sexually active, talk to your healthcare provider about which STI tests are right for you, and don’t forget to mention oral and anal sex so all exposed sites can be checked.

Frequently Asked Questions
Can you get gonorrhea from oral sex?
Yes. Gonorrhea can infect the throat through oral sex, and it can also be passed from an infected throat to a partner’s genitals. Oral (throat) gonorrhea usually causes no symptoms, so many people don’t know they have it.
Does a standard STI test check for oral gonorrhea?
Not automatically. A routine urine test only detects genital gonorrhea. Detecting throat gonorrhea requires a throat swab, which providers usually only do if you tell them about oral sex exposure — so it’s important to mention it.
How is gonorrhea treated?
Uncomplicated gonorrhea is treated with a single injection of ceftriaxone (500 mg), which covers infection at the throat, genitals, and rectum. Partners should be treated too, and a test of cure is recommended 7–14 days later for throat infections.
Is oral gonorrhea serious?
It rarely causes symptoms, but it matters: it can spread to partners and the throat can be a site where antibiotic resistance develops. Treatment is recommended even when there are no symptoms.
