Gonorrhea Infection

What is Gonorrhea infection?

Gonorrhea is a common sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. The organism spreads through vaginal, anal, or oral sex with an infected partner. If left untreated, it can affect the urethra, cervix, rectum, throat, and even the eyes. In women, untreated gonorrhea increases the risk of pelvic inflammatory disease (PID), infertility, and ectopic pregnancy. In men, it can cause epididymitis, which may also lead to infertility.

According to the CDC, more than 600,000 cases were reported in the United States in 2022, making it the second‑most common bacterial STI after chlamydia.

Common Causes

Gonorrhea itself is not caused by other medical conditions, but certain behaviors and co‑existing infections increase the likelihood of acquiring it. The most important risk factors include:

• Unprotected vaginal, anal, or oral sex
• Having multiple sexual partners or a partner with multiple partners
• Previous STI (e.g., chlamydia, syphilis, herpes) – the genital tract may be more susceptible
• Inconsistent or incorrect use of condoms
• Substance use that impairs judgment (alcohol, drugs)
• Sex work or exchange of sex for goods
• Being a man who has sex with men (MSM) – higher prevalence in some networks
• Pregnancy (vertical transmission to newborn during delivery)
• Living in or traveling to areas with high STI rates

Associated Symptoms

Many people with gonorrhea have no symptoms, especially women. When symptoms do appear, they usually develop within 2‑14 days after exposure.

In people assigned male at birth

• Burning or painful urination
• White, yellow, or green discharge from the penis
• Swollen or painful testicles (epididymitis)
• Rectal pain, discharge, or bleeding (if infected anally)
• Sore throat (after oral sex)

In people assigned female at birth

• Increased vaginal discharge that may be watery, creamy, or yellow
• Burning sensation during urination
• Bleeding between periods or after intercourse
• Lower abdominal or pelvic pain
• Rectal pain, discharge, or bleeding (if infected anally)
• Sore throat (after oral sex)

Systemic symptoms such as fever, joint pain, or skin lesions can occur if the infection spreads (disseminated gonococcal infection, DGI).

When to See a Doctor

Prompt medical evaluation is crucial because untreated gonorrhea can cause long‑term complications. Seek care if you experience any of the following:

• Any new genital, rectal, or throat discharge
• Painful or burning urination
• Unexplained lower‑abdominal or pelvic pain
• Bleeding between periods, after sex, or after a bowel movement
• Swollen or tender testicles
• Fever, chills, or a rash that looks like small red or purple spots
• Pregnant and suspect exposure – early treatment helps protect the baby

Even if you feel fine, consider testing if you have had a recent unprotected sexual encounter, especially with a new or multiple partners.

Diagnosis

Healthcare providers use a combination of history, physical examination, and laboratory testing.

• NAAT (Nucleic Acid Amplification Test): The most sensitive test. Samples can be taken from urine, vaginal or cervical swabs, rectal swabs, or throat swabs.
• Culture: Used when antibiotic susceptibility testing is needed, especially for suspected treatment‑failure or in areas with high antimicrobial resistance.
• Gram stain: May show gram‑negative diplococci in men with urethral discharge, but not reliable in women.
• Blood tests: Typically not needed for uncomplicated infection, but performed when DGI is suspected.

Because co‑infection with chlamydia is common (up to 30‑40% of cases), clinicians usually test and treat for both simultaneously.

Treatment Options

Gonorrhea has become increasingly resistant to many antibiotics. Current CDC‑recommended regimen (2024) is:

• Dual therapy: A single intramuscular dose of ceftriaxone 500 mg (≥150 kg: 1 g) plus a single oral dose of azithromycin 1 g.

For individuals allergic to cephalosporins, alternatives include gentamicin plus azithromycin or a carbapenem, but these are less studied.

Partner Management – All sexual partners from the past 60 days should be notified, tested, and treated, even if asymptomatic.

Home Care & Symptom Relief

• Finish the full antibiotic course even if symptoms improve.
• Avoid sexual activity until you and your partner(s) have completed treatment and a follow‑up test of cure (usually 1 week after therapy) is negative.
• Use over‑the‑counter pain relievers (ibuprofen or acetaminophen) for discomfort.
• Stay well‑hydrated and urinate frequently to help flush the urinary tract.

If you develop a rash, joint swelling, or fever after starting antibiotics, contact your provider immediately – this may signal an allergic reaction or disseminated infection.

Prevention Tips

• Consistent condom use: Use latex or polyurethane condoms correctly for every vaginal, anal, and oral sex act.
• Limit number of partners: Fewer partners reduce exposure risk.
• Regular STI screening: At least annual testing for sexually active individuals; more often if you have multiple partners or belong to high‑risk groups.
• Pre‑exposure prophylaxis (PrEP) programs: While PrEP prevents HIV, many clinics pair it with routine STI testing.
• Vaccinations: Hepatitis B and HPV vaccines do not prevent gonorrhea but protect against other STIs that can coexist.
• Open communication: Discuss STI testing and status with current and prospective partners.
• Avoid douching or intravaginal products: They can disrupt normal flora and increase susceptibility.
• Pregnant women: Routine prenatal screening at the first prenatal visit; treat promptly to prevent neonatal conjunctivitis.

Emergency Warning Signs

If you experience any of the following, seek emergency medical care (ER or urgent care) immediately:

• Severe abdominal or pelvic pain with fever – possible pelvic inflammatory disease or tubo‑ovarian abscess.
• Sudden swelling, redness, or extreme pain in the testicles – could be epididymitis or torsion.
• Rash with joint pain and/or swelling (may appear as small red or purple spots) – signs of disseminated gonococcal infection.
• Difficulty breathing, severe allergic reaction (hives, swelling of face or throat) after taking antibiotics.
• Persistent vomiting or inability to keep fluids down, which could lead to dehydration.

Key Take‑aways

Gonorrhea is a highly treatable bacterial infection, but its increasing antibiotic resistance makes early detection and proper therapy essential. Regular screening, honest communication with partners, and consistent condom use remain the most effective tools for prevention. If you suspect exposure or notice symptoms, don’t wait—schedule a test and begin treatment promptly to avoid complications.
