Lymphogranuloma venereum (LGV)


Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis belonging to the species L-serovar. LGV is characterized by the formation of swollen lymph nodes and sores in the genital area. It can cause genital ulcers, pain, swelling, fever, and fatigue. In some cases, it can also cause eye, heart, and joint problems if left untreated. LGV is usually transmitted through unprotected sexual contact with someone infected with the bacteria. Treatment involves antibiotics. If caught early enough, the infection can often be cured without complications.


The symptoms of Lymphogranuloma venereum (LGV) can vary depending on which stage of the infection a person is in.

In the first stage, LGV often causes an asymmetric painless genital ulcer, which is accompanied by tender lymph nodes close to the affected area. This stage is known as the proctocolitic stage.

In the second stage, LGV can cause fever, headache, muscle pain, swollen and enlarged lymph nodes, and skin rashes. This stage is known as the inguinal stage.

The third and final stage of LGV is known as the regional stage and can cause swelling of the lymph nodes in the groin, abdomen, or lower extremities. This swelling can cause skin rashes, abscesses, and, in later stages, fistulas.

If left untreated, LGV can cause abscesses in the liver, spleen, and even the heart. It can also cause serious complications, such as blindness, hearing loss, anemia, and even death.

Seek medical attention as soon as possible if you experience any of these symptoms.


The primary cause of Lymphogranuloma venereum (LGV) is infection with the bacteria Chlamydia trachomatis, particularly serovars L1, L2, and L3. These serovars are most often spread through sexual contact, particularly during unprotected intercourse. Other means of transmission may include contact with contaminated objects, such as clothing or bed linens.

Risk factors

The primary risk factors for Lymphogranuloma venereum (LGV) are engaging in unprotected sex, having multiple sexual partners, and having HIV or another sexually transmitted infection. People with weakened immune systems, such as people with HIV, may be more likely to develop LGV. It is also more common in people who are exposed to contaminated water or live in areas where it is more common. Other risk factors include living in or traveling to tropical or subtropical climates, being a man who has sex with men, and having an occupational exposure to another person with LGV.


Lymphogranuloma venereum, or LGV, can be diagnosed through a combination of a physical examination and laboratory testing. During the physical exam, a doctor will examine for genital lesions and swollen lymph nodes in the groin and anoscopy to confirm the presence of the infection. Laboratory tests such as the polymerase chain reaction (PCR) test and serologic testing can also be used to accurately diagnose LGV. The PCR test helps identify the presence of an infection, while the serologic test helps to identify if a person has been exposed to Chlamydia trachomatis, the bacteria responsible for LGV.


Lymphogranuloma venereum (LGV) is a bacterial infection caused by Chlamydia trachomatis that is typically transmitted through contact with infected body fluids during sexual activity. LGV is classified into three subtypes based on the genotypes of Chlamydia trachomatis that cause it: subtype L1, found mainly in Africa and Asia; subtype L2, found mainly in the Americas; and subtype L3, found worldwide.

Subtype L1 is associated with severe symptoms and can cause genital ulcers, inguinal lymphadenopathy, and rectal, perianal, and vaginal strictures. Subtype L2 is the most common form of LGV, and its symptoms include tender regional lymphadenopathy, necrotizing lymphadenitis, and systemic illness in some cases. Subtype L3 is the least common form of LGV, and its symptoms are usually milder than those of the other two subtypes. In general, LGV can cause fever, malaise, anorectal or genital ulcerations, and swollen lymph nodes. It is essential that LGV is treated immediately to reduce the risk of complications including infertility, fistulas, and abscesses.


The main treatment for Lymphogranuloma venereum (LGV) is antibiotics. Depending on the severity of the infection, the doctor may prescribe a single, large dose of antibiotics or multiple doses taken over several weeks. The specific type of antibiotic used to treat LGV may vary, but commonly used antibiotics include doxycycline, erythromycin, tetracycline, and azithromycin. In severe cases, corticosteroid medications may also be prescribed to reduce inflammation. Surgery may also be recommended in severe cases of genital swelling or lymph node abscesses.


To reduce the risk of LGV, individuals should practice safer sex by using condoms every time they engage in sexual intercourse, get regularly tested for STIs, abstain from sexual contact, and limit the number of sexual partners. People should also be aware of any signs and symptoms of LGV, such as genital sores, rashes, or swollen lymph nodes, and seek medical attention immediately if they experience any of them. Additionally, healthcare providers should ensure that individuals are tested and screened for LGV when necessary. Finally, individuals should be knowledgeable of LGV and its related risks, practice proper hygiene, and get vaccinated against hepatitis A and B, which can help reduce the risk of developing LGV.

Gender differences?

Yes, there are gender-specific differences in the presentation and management of Lymphogranuloma venereum (LGV). Men, especially those infected with the human immunodeficiency virus (HIV), are more likely to present with anogenital lesions, such as papules and ulcers, compared to women. Furthermore, women with LGV infection may present with more atypical symptoms than men, such as pelvic pain, dysuria and dyspareunia. In terms of management, the cephalosporin antibiotics recommended for LGV treatment are more effective in men than in women. This is likely related to differences in antibiotics metabolism and hormonal influences.


Nutrition plays an important role in the effective management of Lymphogranuloma venereum (LGV). Proper nutrition helps to boost the body’s natural defense mechanisms, allowing it to fight off infection more effectively. It can also help reduce inflammation, which is a key symptom of the condition. Eating a balanced diet full of fresh fruits and vegetables, lean proteins, and whole grains can help improve overall health and boost the body’s defenses against LGV. An adequate intake of vitamins and minerals is also important for immune health. Additionally, drinking plenty of water and keeping hydrated can help reduce the severity of symptoms associated with LGV.

Physical Activity

Physical activity has not been directly linked to LGV, or lymphogranuloma venereum. However, physical activity can increase your overall immune health and wellness which may help to prevent you from contracting LGV or other infections through contact with the disease-causing bacteria. Regular physical activity can also help you manage other concurrent symptoms or comorbidities. For example, physical activity can help to alleviate some of the fatigue that often accompanies chronic infections such as LGV. Exercise can also help to reduce stress and improve mood, which may also help to manage symptoms associated with LGV.
