Information for Patients


Also called: Trich

Trichomoniasis is a sexually transmitted disease caused by a parasite. You get it through sexual intercourse with an infected partner. Many people do not have any symptoms. If you do get symptoms, they usually happen within 5 to 28 days after being infected.

Symptoms in women include

  • Yellow-green or gray discharge from the vagina
  • Discomfort during sex
  • Vaginal odor
  • Painful urination
  • Itching in or near the vagina

Most men do not have symptoms. If they do, they may have a whitish discharge from the penis and painful or difficult urination and ejaculation.

Lab tests can tell if you have the infection. Treatment is with antibiotics. If you are infected, you and your partner must be treated. Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading trichomoniasis.
