Men are tested for mycoplasma and chlamydia, often to confirm the diagnosis of non-gonococcal urethritis, which is a urinary tract infection and a sexually transmitted disease. It is often seen in men with a history of unclean sexual contact that leads to infection in themselves or their partners. After infection, patients may experience itching in the urethra, frequent urination, urgency, burning urination, and increased urethral discharge, which may be white or yellowish thin discharge. The infection may be aggravated with fever and may be accompanied by male epididymitis. If the culture of mycoplasma and chlamydia is positive, it is recommended to abstain from sexual intercourse and to treat with intravenous infusion of macrolide antibiotics. Azithromycin 0.5g can be chosen for intravenous infusion once daily for 7-10 days. If there are regular sexual partners, it is recommended that both partners be tested for mycoplasma and chlamydia at the same time or that both partners be treated together until the re-test for mycoplasma and chlamydia turns negative.
