Understanding Lymphogranuloma Venereum: Symptoms and Treatment
Lymphogranuloma venereum (LGV) is a sexually transmitted infection (STI) caused by certain strains of the bacterium Chlamydia trachomatis. Although relatively rare in comparison to other STIs, understanding LGV is crucial for effective diagnosis and treatment. This article delves into the symptoms, causes, and treatment options for LGV, while distinguishing it from other STIs.
What is Lymphogranuloma Venereum?
Lymphogranuloma venereum is a chronic infection of the lymphatic system. It is primarily spread through sexual contact and is more prevalent among men who have sex with men (MSM). Although LGV can be asymptomatic in its initial stages, it can lead to severe health complications if left untreated.
Lymphogranuloma Venereum vs. Other STIs
LGV is often confused with other STIs due to overlapping symptoms. However, it is distinct in its cause and progression. Unlike other chlamydial infections, LGV is caused by the L1, L2, and L3 serovars of Chlamydia trachomatis. These serovars are more invasive, causing systemic infection and affecting the lymphatic system.

Get A Second OpinionCauses and Risk Factors
The primary cause of LGV is the transmission of the Chlamydia trachomatis bacterium through sexual contact. The infection thrives in populations with high rates of partner change and unprotected sexual activities. The following factors increase the risk of contracting LGV:
- Engaging in unprotected anal or vaginal intercourse
- Having multiple sexual partners
- Being part of high-risk populations, such as MSM
- Co-infection with HIV, which compromises the immune system
Symptoms of Lymphogranuloma Venereum
The symptoms of LGV are characterized by three distinct stages:
Primary Stage
The primary stage of LGV often goes unnoticed due to the mild nature of symptoms. It begins with the appearance of a minor, painless ulcer at the site of infection, which typically resolves within a few days. This transient ulcer can be easily overlooked or mistaken for a minor irritation.
Secondary Stage
During the secondary stage, the infection spreads to the lymph nodes. This stage is marked by painful swelling of the inguinal and femoral lymph nodes, a condition known as "inguinal syndrome." These swollen nodes, also called buboes, may rupture and drain pus if left untreated. Other symptoms include fever, malaise, and muscle pain.
Tertiary Stage
If untreated, LGV can progress to the tertiary stage, characterized by chronic inflammation and scarring. This may lead to complications such as rectal strictures, genital elephantiasis, and infertility. The tertiary stage is less common in the era of modern antibiotics but can still occur in untreated cases.
Complications of Lymphogranuloma Venereum
The complications of LGV can be severe and impact quality of life significantly. They include:
- Chronic pain and swelling in the affected lymph nodes
- Rectal strictures, leading to bowel obstruction or difficulty defecating
- Genital elephantiasis due to lymphatic obstruction
- Increased risk of secondary infections due to open sores
- Infertility as a result of scarring in reproductive organs
Diagnosing Lymphogranuloma Venereum
Accurate diagnosis of LGV involves both clinical assessment and laboratory testing. Clinicians will consider the patient's symptoms, sexual history, and risk factors. Diagnostic tests may include:
- Nucleic acid amplification tests (NAATs) to detect Chlamydia trachomatis DNA
- Serological tests to identify specific antibodies
- Biopsy of affected lymph nodes in advanced cases

Book an AppointmentTreatment Options for Lymphogranuloma Venereum
The cornerstone of LGV treatment is antibiotic therapy, which aims to eradicate the bacterial infection. The most commonly prescribed antibiotics include:
- Doxycycline: Administered orally for a minimum of 21 days, doxycycline is the preferred treatment due to its effectiveness in resolving symptoms and preventing complications.
- Erythromycin: An alternative for those who are intolerant to doxycycline, erythromycin is also effective but requires a longer treatment duration.
- Azithromycin: While less commonly used for LGV, azithromycin may be prescribed in certain cases due to its convenient single-dose regimen.
In severe cases, additional interventions may be necessary to manage complications. These can include:
- Surgical drainage of buboes to alleviate discomfort and prevent rupture
- Anorectal surgery to address strictures or fistulas
- Pain management strategies to improve quality of life during recovery
Preventing Lymphogranuloma Venereum
Prevention of LGV centres around reducing the risk of exposure to the causative bacteria. This includes:
- Practicing safe sex by consistently using condoms
- Reducing the number of sexual partners
- Regular STI screening, particularly for high-risk populations
- Prompt treatment of any diagnosed STIs to prevent progression or transmission
