Trichomoniasis may cause no symptoms, especially in men. Symptoms may include:

In Women:

  • A foul-smelling, greenish-yellow discharge from the vagina (often in large amounts)
  • Irritation, itching, and/or soreness in the vulva, perineum, and (less often) the thighs
  • In severe cases, inflammation of the vulva and perineum
  • Red spots on the vaginal walls and surface of the cervix
  • Pregnant women who are infected with trichomoniasis may have premature or low-birth weight babies

  • Discharge from the penis (usually in the morning)
  • Itching and/or irritation in the urethra and (less often) the thighs
  • Pain or discomfort when urinating
  • Burning sensation after ejaculation
  • Men may have no symptoms, or symptoms may disappear after several weeks; however, even without symptoms, an infected man may continue to infect his sexual partners

The doctor will ask about your symptoms and medical history, and perform a physical exam. This may include the following:

In Women:

  • Exam of vaginal walls and cervix
  • Microscopic exam of vaginal fluid or discharge
  • Pap smear test may indicate Trichomonas , but it is not deliberately used to diagnosis the infection

In Men:

  • Microscopic exam of urethral discharge (collected prior to first void in the morning)
  • Urine test
