Women:

• Discomfort with intercourse
• Itching of the inner thighs
• Vaginal discharge (thin, greenish-yellow, frothy or foamy)
• Vaginal itching
• Vulvar itching or swelling of the labia

Occasionally, some men with trichomoniasis may develop prostatitis or epididymitis from the infection.

In women:

A pelvic examination reveals red blotches vaginal wall or cervix. A wet prep (microscopic examination of discharge) shows the infection-causing organisms in vaginal fluids. A pap smear may also diagnose the condition.

In men:

The disease can be hard to diagnose in men. Men are treated if the infection is diagnosed in any of their sexual partners. Men may also be treated if they have ongoing symptoms of urethral burning or itching despite treatment for gonorrhea and chlamydia.
