What Is Ureaplasma?
What is Ureaplasma? Symptoms, testing and treatment
Ureaplasma is a group of bacteria that can be present in the genital and urinary tracts of some healthy people without causing symptoms. Therefore, detecting Ureaplasma in a test does not, on its own, mean there is an infection or that treatment is needed. In particular, Ureaplasma parvum is usually considered clinically insignificant colonisation. U. urealyticum, however, may cause symptomatic urethritis in some men after other causes have been ruled out.
What symptoms does Ureaplasma cause?
Most people who carry Ureaplasma have no symptoms. Symptoms such as burning during urination, urethral discharge or discomfort in the genital area may occur; however, these are not specific to Ureaplasma and may also be caused by other infections or non-infectious conditions.
In women with vaginal discharge or urinary symptoms, these should not be assumed to be directly caused by Ureaplasma. More common and clinically important causes, such as chlamydia, gonorrhoea, trichomoniasis and bacterial vaginosis, should be assessed. The CDC does not recommend testing for U. parvum and U. urealyticum when evaluating cervicitis.
How is Ureaplasma testing performed?
The genetic material of Ureaplasma can be detected in suitable samples using PCR/NAAT. The type of sample used—for example, urine or a genital swab—is determined by the symptoms, the testing method and the laboratory’s sample acceptance requirements.
Routine screening for Ureaplasma in everyone without symptoms is not recommended. If symptoms are present, the doctor first assesses the examination and clinical findings and, when necessary, requests tests for pathogens such as chlamydia and gonorrhoea. A positive PCR result indicates that the bacterium is present in the sample; it does not, on its own, prove the cause of the symptoms. In cases of cervicitis, the CDC also recommends assessment for chlamydia, gonorrhoea, trichomoniasis and bacterial vaginosis according to the clinical situation, rather than Ureaplasma testing.
How is Ureaplasma treated?
If there are no symptoms or no signs of disease other than a positive test result, antibiotic treatment is generally not needed. Unnecessary antibiotic use can cause side effects, antibiotic resistance and disruption of the normal balance of genital flora.
The decision to treat is made by a doctor after assessing symptoms, examination findings and test results for other possible pathogens together. The European Association of Urology’s 2026 guideline recommends considering treatment only when U. urealyticum is the only possible cause of symptomatic urethritis. The guideline lists doxycycline as an option for patients considered suitable by their doctor, and azithromycin when doxycycline cannot be used. Antibiotics should not be started or repeated without a doctor’s recommendation.
Does my partner also need testing or treatment?
A positive Ureaplasma test result does not, on its own, mean that a partner also needs testing or antibiotics. Partner assessment should be planned with a doctor, based on whether the individual has a confirmed infection or a clinical condition such as urethritis, and on other test results.
When should I see a doctor?
See a doctor if you have burning during urination, urethral discharge, persistent genital symptoms or a risk of a sexually transmitted infection. Seek medical assessment without delay if you have fever, lower abdominal or pelvic pain, testicular pain or new symptoms during pregnancy.
In brief: Ureaplasma can often be present without causing symptoms. If symptoms are present, their cause should not be determined solely from a PCR result; decisions about testing and treatment should be based on clinical assessment.
