Gonorrhea, caused by a gram-negative diplococcus Neisseria gonorrhoeae, is a well-recognized sexually transmitted infection throughout the world, with incidence rates peaking in the United States and Eastern Europe [1] [2]. It is most frequently diagnosed in the population of younger sexually active adults (aged between 15-24 years) [1] [2] [3]. African American or Hispanic ethnicity is a significant risk factor for the infection, as studies have found a 19-fold increased risk compared to Caucasians [1] [2] [3]. The transmission of N. gonorrhea mandates sexual contact, including rectal and orogenital, and several clinical forms of male gonorrhea have been described in the literature [1] [2] [3] [4] [5]:

• Gonococcal urethritis - By far, the most important type of infection in males involves the urethra, in the form of acute anterior urethritis [1] [3]. Signs and symptoms, appearing after an incubation period of 1-10 days (although the mean onset is observed after 2-5 days), are urethral discharge followed by dysuria [2] [3]. At first, the discharge is mucoid or mucopurulent, but within the first 24 hours of symptom onset, it is evidently purulent and profuse and is the hallmark of male gonorrhea [1] [2] [3]. Discharge is accompanied by dysuria, but without the sense of urgency and increased urinary frequency [2] [4]. Complete resolution of symptoms after several months is the usual clinical progression, but various complications may arise, such as prostatitis (acute or chronic), epididymitis, seminal vesiculitis and other local infections [4]. In some cases, however, gonococcal urethritis can be completely asymptomatic, in which case a significant risk for transmission to other individuals exists [2] [3].
• Rectal infection - Typically encountered in the men who are having sex with men (MSM) population (but also in women), rectal gonococcal infection is acquired by receptive anal intercourse [2]. Although many patients are asymptomatic, acute proctitis, presenting as tenesmus, pruritus, constipation, rectal pain, purulent rectal discharge and even bleeding, might develop [2] [3].
• Gonococcal pharyngitis and conjunctivitis - Transmission of N. gonorrhea to the oropharynx or the eyes usually result in a mild or asymptomatic clinical presentation in males [3]. In rare cases, erythema and the presence of an exudate in the throat are noted, whereas photophobia, exudation, and local pain are seen in gonococcal conjunctivitis [2] [3].
• Disseminated gonococcal infection (DGI) - In very few patients, hematogenous dissemination from localized infections can lead to bacteremia and systemic manifestations of the disease, most important being arthritis and various skin lesions [1] [2] [3] [4]. Gonorrhea is the most common cause of septic arthritis in adults, and the initial presentation of polyarthralgia and constitutional symptoms followed by asymmetric pain and swelling of one or two joints is typical for gonococcal arthritis [2] [5]. Conversely, almost 75% of DGI patients exhibit skin lesions - macules, papules, pustules, petechiae, vesicles, and bullae [3].

• Fever

  Report of a Case A 26-year-old Negro man was admitted to USAF Hospital Andrews on May 5, 1965, for recurrent fever, polyarthralgia, and a skin eruption of nine weeks' duration. [jamanetwork.com]

  You should seek medical attention if you feel sick, have a fever or pelvic pain, or experience pain during sex. [stdcheck.com]

  PID is characterized by pain in the pelvis and lower abdomen, as well as nausea, vomiting, fevers, chills, cramping, and a foul-smelling discharge. [verywellhealth.com]

  Fever with abdominal pain, pelvic pain, and vaginal discharge can be symptoms of this disease. Men: Fever, discharge from the penis, and painful urination may signal an infection, especially involving inflammation of the testicles. [emedicinehealth.com]

• Malaise

  Very rarely, the infection can settle in the heart and cause inflammation of the heart valves ( endocarditis ), manifesting with symptoms of malaise, fever, chills, and a heart murmur. [verywellhealth.com]

  Other common symptoms include skin rashes and arthritis, nausea, vomiting, loss of appetite, malaise, abdominal pain, and jaundice (yellowing of the eyes and skin). [luckymojo.com]

• Localized Pain

  In rare cases, erythema and the presence of an exudate in the throat are noted, whereas photophobia, exudation, and local pain are seen in gonococcal conjunctivitis. [symptoma.com]

• Constitutional Symptom

  Gonorrhea is the most common cause of septic arthritis in adults, and the initial presentation of polyarthralgia and constitutional symptoms followed by asymmetric pain and swelling of one or two joints is typical for gonococcal arthritis. [symptoma.com]

• Unsafe Sexual Practices

  Individuals who engage in unsafe sexual practices and those with a history of past gonococcal infections are at increased risk for contracting N gonorrhoeae. [uspharmacist.com]

• Aspiration

  The stomach should be empty during the procedure to facilitate inspection of its lining and to avoid vomiting and aspiration of liquids into the lungs. A sedative is given before the examination. [kpjkuching.com]

  These tests are used when conjunctivitis, disseminated infections, or arthritis (if the joint fluid aspirate is the optimal sample in that case) are suspected, whereas cultivation is recommended over gram staining and NAAT in gonococcal pharyngitis and [symptoma.com]

  An affected joint should be aspirated, and fluid should be sent for culture and routine analysis (see Arthrocentesis ). Patients with skin lesions, systemic symptoms, or both should have blood, urethral, cervical, and rectal cultures or NAAT. [merckmanuals.com]

  The joints will be swollen and warm, and a joint aspiration will detect more than 40,000 leukocytes per mm 3 (40 × 10 9 per L) and contain gram-negative intracellular diplococci. [aafp.org]

• Tenesmus

  Although many patients are asymptomatic, acute proctitis, presenting as tenesmus, pruritus, constipation, rectal pain, purulent rectal discharge and even bleeding, might develop. [symptoma.com]

  Rectal pain, tenesmus, and bleeding are more common in MSM. Severe gonococcal rectal infections may be difficult to differentiate from inflammatory bowel disease. [aafp.org]

  […] strictures: Have become uncommon in the antibiotic era, but they can present with a decreased and abnormal urine stream, as well as with the secondary complications of prostatitis and cystitis Rectal infection: May present with pain, pruritus, discharge, or tenesmus [emedicine.medscape.com]

• Dysuria

  Discharge is accompanied by dysuria, but without the sense of urgency and increased urinary frequency. [symptoma.com]

  Gonorrheal epididymitis may be identified by dysuria, a foul-smelling discharge, painful ejaculation, and swollen lymph nodes in the groin. As with PID, the blockage of one or both tubes can lead to functional infertility. [verywellhealth.com]

  Gonorrhea is one of the most commonly recognized sexually transmitted diseases (STDs) worldwide, and gonococcal urethritis, characterized by urethral discharge and dysuria, is the predominant manifestation in males. [symptoma.com]

  Culture Urethral swab Only required if discharge or other local symptoms present. Gram stained urethral discharge may show gram negative intracellular diplococci but is not a sensitive test at non-urethral sites. [sti.guidelines.org.au]

  They then complain only of mild dysuria with a mucoid urethral discharge as observed in nongonococcal urethritis. [dartmouth.edu]

  C 32, 33 Based on limited studies Nomenclature Historically, the term urethritis was reserved for patients with urethral discharge. [aafp.org]

• Painful Ejaculation

  Gonorrheal epididymitis may be identified by dysuria, a foul-smelling discharge, painful ejaculation, and swollen lymph nodes in the groin. As with PID, the blockage of one or both tubes can lead to functional infertility. [verywellhealth.com]

Despite the fact that microbiological confirmation is necessary to make the diagnosis of gonorrhea in males, a complete physical examination and a thorough patient history are vital in raising clinical suspicion. In adult males who present with purulent discharge from the urethra or conjunctiva, or who suffer from an asymmetric polyarthralgia, gonorrhea must be included in the differential diagnosis. For this reason, data regarding recent sexual activity is of vital importance. Patients should be asked about the number of partners and if there have been any "risky" sexual contacts. Then, appropriate microbiological studies need to be carried out. In the setting of gonococcal urethritis, a sample of the urethral discharge, a urethral swab, or even urine (the first 10-15 mL) are all viable specimens for testing, and either gram-stained smears (carrying a high rate of diagnosis) or cultivation of the obtained material are recommended [6] [7]. Some authors advocate the use of nucleic acid amplification test (NAAT), which can detect bacterial DNA in urine or exudate, but its efficacy is variable [2] [3] [6]. These tests are used when conjunctivitis, disseminated infections, or arthritis (if the joint fluid aspirate is the optimal sample in that case) are suspected, whereas cultivation is recommended over gram staining and NAAT in gonococcal pharyngitis and rectal infections [2] [5] [6]. Because it is not uncommon for patients to suffer from more than one STD, an extensive diagnostic panel should be performed, in order to exclude chlamydia trachomatis (the most common STD worldwide), syphilis, but also hepatitis and human immunodeficiency virus (HIV) infection.

Symptoms may clear up in a few weeks or months, even without treatment. However, without treatment, the bacteria that cause NGU can stay in the urethra. This means that even if symptoms clear, you can still have an infection. [fairview.org]

These studies found that treatment of chlamydial infection was associated with significantly lower rates of preterm delivery, early rupture of membranes, and infants with low birthweight compared with no treatment or treatment failure. [uspreventiveservicestaskforce.org]

Prognosis [ 6 ] Where treatment is rapidly received for a recently acquired gonorrhoeal infection, prognosis is good with full recovery as normal. [patient.info]

Prognosis If gonorrhea infections are diagnosed and treated quickly and correctly, recovery usually is complete unless pelvic inflammatory disease (PID) develops. PID is more likely to develop if treatment is delayed. [drugs.com]

Prevention and Management Considerations Appropriate treatment is of paramount importance for existing gonococcal infections, but preventive measures must also be considered and discussed with the patient. [uspharmacist.com]

It's a good idea to start thinking about prevention now. Not having sex is the best way to prevent any sexually transmitted infection. Follow-up care is a key part of your treatment and safety. [myhealth.alberta.ca]

“In rare cases, this may cause a man to be sterile, or prevent him from being able to father a child.” Also in rare cases, the gonorrhea can increase the chance of spreading or contracting HIV. [medicaldaily.com]

The only way to prevent gonorrhea and other STDs is to not have sex (oral, vaginal, or anal). If someone decides to have sex, using a latex condom every time can prevent most STDs. [kidshealth.org]
