Trichomoniasis, a sexually transmitted disease, rarely causes symptoms in men, according to WebMD, but burning during urination, discharge from the penis and mild penile irritation may be present when symptoms do occur. Women with trichomoniasis often experience painful urination, frothy green vaginal discharge, vaginal irritation and painful intercourse. These symptoms appear within five to 28 days of exposure, and infected women may have a higher risk of contracting HIV and transmitting the disease to sexual partners.
WebMD explains that diagnosis of this STD is done by performing lab tests on urethral or vaginal fluids to detect the parasite that causes the disease. A course of the antibiotic metronidazole usually eliminates the condition. It is advisable for both sexual partners to receive antibiotic treatment simultaneously and to avoid sexual activity until both partners have completed treatment and are symptom free.
Trichomoniasis is a sexually transmitted infection caused by the parasite Trichomonas vaginalis, according to the Centers for Disease Control and Prevention. Transmission is typically limited to vaginal and penile contact, rarely affecting the anus or mouth. Women are infected more often than men, and the infection usually develops in the lower genital tract, consisting of the vagina, vulva and urethra. In men, the parasite commonly infects the urethra, the canal that makes up the inside of the penis.
