LGV

LGV (lymphogranuloma venereum) is a sexually transmitted infection (STI) that attacks the lymph nodes. It has been spreading among gay and bisexual men since arriving in the UK around 2004. More than 1,500 cases had been diagnosed by the end of 2010.

New figures from the Health Protection Agency show that cases in London increased dramatically from 130 in 2009 to 340 in 2010, the highest number to date. London currently has two-thirds of the cases seen nationally, with further concentrations of cases in Brighton and Manchester.

LGV is caused by a rare type of Chlamydia bacteria and is cured with antibiotics.

How is LGV passed on?

Men with lots of sexual partners are at most risk. Unprotected anal sex and fisting without latex gloves are the main ways the infection is spread. Using sex toys, like dildos, on more than one person can also spread the bacteria, as can sharing enema equipment.

Symptoms

A few people have had LGV without noticing but most get symptoms within a few weeks of becoming infected.

The vast majority of men are getting LGV in the anus, causing painful inflammation (called 'proctitis') often with constipation, ulcers, pus and bleeding. There may be fever too. Some men get a small, painless sore where the bacteria entered the anus or penis.

LGV in the penis can cause discharge, pain when urinating and the glands in the groin can swell. LGV in the throat is rare but it can make the glands in your neck swell.

Treatment

If treated in time LGV is cured with three weeks of antibiotics. Left untreated, LGV can cause lasting damage.

Protect yourself and others

You can reduce the risk of getting LGV if you use condoms, and use latex gloves for fisting. During group sex don’t let the same latex glove or the same condom-covered penis go from one man’s anus to another’s. If you share sex toys, cover them with a fresh condom for each person they’re used with and avoid sharing enema or douching equipment. Wash sex toys and hands with warm water and antibacterial soap between each new partner.

If you have any symptoms, especially inflammation of the anus, don't have sex until you've had a check-up at a sexual health (GUM) clinic.
