Lymphogranuloma venereum (LGV) is a sexually transmitted disease (STD) caused by a type of chlamydia trachomatis (serovars L1, L2, or L3) that rarely occurs in the United States and other industrialized countries. However, recent outbreaks of LGV have been reported among men who have sex with men (MSM) in Europe and other U.S. cities. If you have signs or symptoms of any sexually transmitted disease you should see a health care provider for evaluation and possible treatment.

  • Always use latex condoms during vaginal and anal sex.
  • Use a latex condom for oral sex on a penis.
  • Use a latex barrier (dental dam or condom cut in half) for oral sex on a vagina or anus.
  • Limit the number of sex partners.
