Most men don’t experience any discomfort from a trichomoniasis infection, but possible symptoms are mild discharge, irritation in the penis, and burning sensations after urinating or ejaculating, WebMD states. Doctors advise men to get tested for trichomoniasis if any sexual partners are diagnosed with the infection.
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.
Doctors diagnose the condition in men by examining a sample of urethral fluid, and they prescribe the oral antibiotic metronidazole to treat the infection, WebMD explains. The infected person should avoid sexual contact until the treatment is complete and use condoms to reduce the risk of developing future infections. Women are more likely to develop trichomoniasis symptoms, such as discomfort during sexual activity, painful urination, vaginal itching and odorous vaginal discharge. 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.
