What is Lymphogranuloma Venereum?
Lymphogranuloma Venereum (LGV) is an infection caused by certain strains of chlamydia (types L1-L3). This bacteria can infect the genitals or anus and may spread to involve the lymph nodes (glands) of the genital area.
How is it transmitted?
It is transmitted by unprotected (no condom) vaginal and anal intercourse. It may also be transmitted by sex toys and fingers if they have been in contact with an infected person’s genitals or anus, although this mode of transmission is not certain. LGV is contagious even when symptoms are not noticeable.
Who gets LGV?
LGV is uncommon in developed countries, however, outbreaks have recently occurred among men who have sex with men (MSM).
What are the signs and symptoms?
When the anus is involved:
This is the most common presentation in men and women who have anal sex. Infection of the anus with LGV can cause anal pain, discharge and trouble using your bowels. The medical term for this is ‘proctitis’.
When the genitals are involved:
The first sign of infection is a pimple, blister or ulcer, which often goes unnoticed. In men it is usually on the penis. In women, it is in the vagina or on the cervix.
The infection then spreads to the lymph nodes (glands) in the groin area—the skin crease between your pubic area and the upper thighs. These glands become inflamed and persistently swollen. People may feel generally unwell at this time.
How long until symptoms develop?
This can vary widely, but the first symptoms may appear 3-30 days after infection.
How do you test for LGV?
Because LGV is not very common, specialised tests need to be done to confirm that LGV is the cause of your symptoms. This will involve swabs from the anus, genitals or lymph nodes if they are swollen. Sometimes blood tests are also done. Unfortunately, these complex tests can take several weeks to give a result. Tests to check for the presence of any other sexually transmitted infections should also be performed.
How is LGV treated?
The treatment course for LGV is longer than the treatment given for other types of chlamydia.
It is treated with antibiotics such as doxycycline or azithromycin for 3 weeks or more.
Should my sexual partners also be treated?
It is extremely important to tell all recent sexual partners that you have been diagnosed with LGV, so they can be tested and treated. If necessary, we can help you notify your partners.
How can I avoid becoming infected again?
The best way to prevent further infections is to practice safe sex by always using a condom.
