Trichomoniasis: Introduction

Trichomoniasis is a common type of sexually transmitted disease. Trichomoniasis is the result of an infection by a tiny parasite called Trichomonas vaginalis.

In trichomoniasis, Trichomonas vaginalis multiples and infects the vagina of a women. In men Trichomonas vaginalis infects the epididymis, prostate, and/or the bladder.

Trichomoniasis is passed from one person another during sexual contact that involves penis-to-vagina intercourse or vulva-to-vulva contact in homosexual women. The more sexual partners a person has, the greater the risk of catching a trichomoniasis infection. Trichomoniasis is generally not spread through contact with such objects as toilet seats.

Trichomoniasis that is diagnosed early can be quickly and easily treated. However, if left untreated trichomoniasis can lead to serious complications, including an increased risk for catching and transmitting other sexually transmitted diseases. Symptoms of trichomoniasis can include vaginal discharge in women, but men may have no symptoms until complications of trichomoniasis develop. For details about additional symptoms and serious complications, refer to symptoms of trichomoniasis.

A diagnosis of trichomoniasis infection can easily be made by taking a medical and sexual history, performing simple trichomoniasis testing, and completing a physical and pelvic examination for women and an exam of the penis and testicles for men. During the examination, the health care practitioner will assess the reproductive organs and take a swab sample of the woman's vagina and cervix or the man's urethra and have it tested for the presence of trichomoniasis. For women with severe symptoms that may indicate the development of pelvic inflammatory disease, a pelvic ultrasound may also be done.

A urine test may also be done to diagnose trichomoniasis of the bladder in men.

Because there may be no symptoms in the early stage of trichomoniasis in men, some infected men may be unaware of a problem, and a diagnosis of trichomoniasis infection can be missed or delayed. In addition, symptoms of trichomoniasis are similar to symptoms of other diseases. For more information on misdiagnosis and diseases that can mimic trichomoniasis, refer to misdiagnosis of trichomoniasis.

The first step in the treatment of trichomoniasis infection is prevention. Prevention of trichomoniasis infection is best accomplished by abstaining from sexual activity or having sex only within a mutually monogamous relationship in which neither partner is infected with trichomoniasis or another sexually transmitted disease. Latex condoms also provide some protection when used properly, but they are not 100 percent effective in preventing the transmission of trichomoniasis and other sexually transmitted diseases.

Trichomoniasis is treatable and curable with medication. Prompt diagnosis and treatment increases the chances of preserving fertility and reducing other complications in both men and women. For more detailed information on treatment, refer to treatment of trichomoniasis. ...more »
