Trichomoniasis is a common sexually transmitted disease. It often affects the lower genital tract in women and inside of the penis in men. Trichomoniasis is treated with antibiotics.

Factors that may increase your chance of trichomoniasis include:

Symptoms in men may include:
The doctor will ask about your symptoms and medical history. A physical exam will be done. Vaginal fluid or discharge will be examined from women. Urine, semen, or penile discharge will be examined from men. The samples can be sent to a lab to confirm trichomoniasis.
Trichomoniasis is can be treated with antibiotics. The antibiotic may be given in a single dose or a weeklong course.
Trichomoniasis is easily passed back and forth between sexual partners. Your partner(s) should also be treated, even if symptoms are not present. An infected person can infect their sexual partners even if they do not have symptoms.
