Recent studies by H. Moi and co-authors add new data to urethritis findings.

In this recent report, researchers in Oslo, Norway conducted a study "To examine the prevalence of Mycoplasma genitalium in a large number of male patients attending a sexually transmitted infections (STI) clinic and to determine if there is an association with objective non-gonococcal urethritis (NGU) in patients with and without clinical symptoms. Patients were tested for both M genitalium and Chlamydia trachomatis if they had symptoms or microscopic signs of NGU or if they were perceived to be at high-risk of exposure to a STI (n = 8468)."

"Urethral smears were examined for polymorphic mononuclear leucocytes. We found that M genitalium infection was associated with symptoms of non-chlamydial NGU (discharge and dysuria; OR 4.3; 95% Cl 3.4 to 5.5). We also found that M genitalium infection was associated with signs of non-chlamydial NGU independently with or without symptoms of NGU (with symptoms: OR 4.7; 95% Cl 3.2 to 6.7; without symptoms: OR 3.1; 95% Cl 2.0 to 4.6). Prevalence of M genitalium was also associated with severity of urethritis as quantified by microscopic examination of urethral smears," wrote H. Moi and colleagues (see ...
