"Trichomonas vaginalis infection in women is frequently symptomatic. 

Vaginitis with a purulent discharge is the prominent symptom, and can be accompanied by vulvar and cervical lesions, abdominal pain, dysuria and dyspareunia. 

The incubation period is 5 to 28 days.

In men, the infection is frequently asymptomatic; occasionally, urethritis, epididymitis, and prostatitis can occur."

"Microscopic examination of wet mounts may establish the diagnosis by detecting actively motile organisms. 

• This is the most practical and rapid method of diagnosis (allowing immediate treatment), but it is relatively insensitive. 

• Direct immunofluorescent antibody staining is more sensitive than wet mounts, but technically more complex.   Culture of the parasite is the most sensitive method, but results are not available for 3 to 7 days. 

• In women, examination should be performed on vaginal and urethral secretions. 

• In men, anterior urethral or prostatic secretions should be examined."
