Lymphogranuloma Venereum (LGV) is a lesser-known but serious sexually transmitted infection (STI) that has become more common in recent years, especially in major cities worldwide. Though it might sound like a rare or outdated disease, LGV is making a quiet resurgence, particularly among sexually active individuals. It’s caused by a specific strain of Chlamydia trachomatis bacteria and, if left untreated, can lead to long-term complications.

At Healthzipp, we believe awareness is the first step toward prevention and better health. In this article, we’ll explain what LGV is, how it spreads, its symptoms, how it’s treated, and most importantly—how you can protect yourself and your loved ones from infection.

What is Lymphogranuloma Venereum (LGV)?

Lymphogranuloma Venereum is a sexually transmitted infection caused by specific strains of the Chlamydia trachomatis bacterium—mainly types L1, L2, and L3. Unlike regular chlamydia infections, which usually affect the genital tract, LGV goes deeper. It infects the lymphatic system, which helps your body fight infection, and can lead to severe inflammation and swelling of lymph nodes in the groin or pelvic area.

Historically, LGV was most common in tropical and subtropical regions such as Africa, Southeast Asia, and the Caribbean. However, in the past two decades, outbreaks have been increasingly reported in Europe, North America, and Australia, especially among men who have sex with men (MSM).

While it’s treatable with antibiotics, early diagnosis is essential to prevent complications and transmission.

How Does LGV Spread?

Lymphogranuloma Venereum spreads primarily through unprotected sexual contact, including vaginal, anal, or oral sex. It is caused by direct contact with infected secretions—fluids from sores or mucous membranes of the genitals or rectum.

The infection can also spread through:

  • Anal intercourse (common route of infection in recent outbreaks)

  • Sharing of sex toys without proper cleaning

  • Contact with broken skin or mucous membranes

Importantly, LGV is not transmitted through casual contact such as hugging, kissing, or sharing food and drinks.

Symptoms of Lymphogranuloma Venereum

LGV develops in three stages, each with its own symptoms and complications. Many people may not realize they are infected during the early stage because the initial symptoms can be mild or mistaken for something else.

Stage 1: Primary Infection

This stage appears 3 to 30 days after exposure. A small, painless sore (ulcer) or blister may appear on the genitals, rectum, or mouth. The sore often heals quickly and might go unnoticed.

Common early symptoms include:

  • Small ulcer or lesion on the genitals or anus

  • Mild irritation or itching

  • Minimal pain or discharge

Because the sore disappears, many individuals mistakenly think they are fine, allowing the infection to progress.

Stage 2: Secondary Stage (Invasion of Lymph Nodes)

This stage typically occurs 2 to 6 weeks after the initial infection and involves the lymphatic system. Swelling and pain develop in the lymph nodes near the infected area.

Symptoms include:

  • Painful, swollen lymph nodes in the groin (often on one side)

  • Fever, chills, and fatigue

  • Rectal pain, discharge, or bleeding (especially in anal infections)

  • Constipation or a feeling of incomplete bowel movements

  • General discomfort or muscle pain

In severe cases, the swollen lymph nodes may form abscesses (collections of pus) that can rupture through the skin, causing open sores.

Stage 3: Chronic Stage (If Untreated)

If not treated, LGV can become chronic and cause serious complications such as:

  • Scarring and narrowing of the rectum (known as rectal stricture)

  • Chronic inflammation or fistulas (abnormal openings between organs)

  • Persistent pain or swelling in the genitals

  • Infertility in severe cases

The third stage can be highly painful and debilitating, highlighting the importance of early detection and medical care.

How is LGV Diagnosed?

Diagnosing LGV can be tricky because its symptoms often resemble other infections like herpes, syphilis, or non-LGV chlamydia.

A healthcare professional will typically:

  1. Take a detailed sexual history to understand potential exposure.

  2. Conduct a physical exam to check for swollen lymph nodes or sores.

  3. Perform laboratory tests, such as:

    • Nucleic acid amplification test (NAAT) for chlamydia detection.

    • Swabs or fluid samples from sores, the rectum, or the urethra.

    • Blood tests to rule out other sexually transmitted infections.

Accurate diagnosis is crucial because LGV requires a longer course of antibiotics than standard chlamydia infections.

Treatment for Lymphogranuloma Venereum

The good news is that LGV is curable with antibiotics. The most common treatment is:

  • Doxycycline (100 mg twice daily for 21 days)

Alternative antibiotics like erythromycin or azithromycin may be prescribed for people who cannot take doxycycline.

In cases of severe infection, where abscesses have formed, drainage procedures may be required. Pain relievers and warm compresses can also help relieve discomfort.

After treatment, follow-up testing ensures the infection has cleared and helps prevent reinfection. It’s equally important that sexual partners are notified, tested, and treated to stop further spread.

Prevention of LGV

Like most sexually transmitted infections, prevention is based on safe sexual practices and regular health checkups. Here’s how to protect yourself and your partner:

  1. Use condoms consistently during vaginal, anal, and oral sex.

  2. Get tested regularly if you are sexually active, especially with multiple partners.

  3. Avoid sharing sex toys or disinfect them between uses.

  4. Limit sexual partners and engage in mutually monogamous relationships.

  5. Seek prompt medical care if you notice unusual sores, discharge, or pain in the genital or rectal area.

Awareness and open communication with partners are key to maintaining sexual health.

Who Is at Higher Risk?

While anyone can contract LGV, certain groups have higher infection rates, including:

  • Men who have sex with men (MSM)

  • People with multiple sexual partners

  • Individuals already diagnosed with other STIs (like HIV or syphilis)

  • People engaging in unprotected anal sex

For these groups, routine STI screenings are especially important, as early detection prevents both transmission and complications.

Why Awareness Matters

Many people underestimate the seriousness of Lymphogranuloma Venereum because it’s not as commonly discussed as other infections like HIV or gonorrhea. However, delayed treatment can lead to long-term pain, scarring, and infertility.

At Healthzipp, we aim to educate readers about such overlooked conditions so they can make informed choices about their health. By raising awareness about LGV, we can help reduce stigma and promote regular screening and safer practices.

Conclusion: Protect Yourself Through Knowledge and Action

Lymphogranuloma Venereum may not be as well-known as other STIs, but its impact can be severe if ignored. The infection begins quietly—with mild or unnoticed symptoms—but can evolve into a painful and chronic illness if left untreated.

The key to prevention lies in education, safe sex practices, and timely medical care. Regular screenings, honest conversations about sexual health, and early treatment are the best defenses against LGV and other sexually transmitted infections.

Your health is your greatest asset—protect it. Stay informed, get tested, and take proactive steps to ensure your well-being.
