Symptomatic men may experience a mild urethral itching or discharge, mild burning after urination or ejaculation, and, on occasion, may develop prostatitis or epididymitis from the infection. Women develop a frothy, foul smelling, green-white or yellowish vaginal discharge . The volume of discharge may be large. Itching may occur on the labia and inner thighs and the labia may appear swollen. Data on the incidence and prevalence of trichomoniasis is not as complete as that for gonorrhea and syphilis .
Figures suggest that it is a frequently encountered infection.
More than half of all females with gonorrhea also have trichomonas. As a rule, individuals with one diagnosed STD frequently have one or more additional sexually-transmitted infections. Trichomonas is present in the sexually active population of all ages. A monogamous sexual relationship with a known healthy partner is the best way of avoiding this and all other sexually-transmitted diseases. Although abstinence provides the greatest protection, it is neither practical nor considered desirable for all people.
