ABSTRACT
<p><b>OBJECTIVE</b>To explore the significance of clue cells in the diagnosis of male urogenital infection.</p><p><b>METHODS</b>Urethra swabs or prostatic fluid of 264 male outpatients were collected and smeared directly on the slice to find clue cells under the ultramicroscopy. Meanwhile, the positive patients' spouses were detected for bacterial vaginosis (BV).</p><p><b>RESULTS</b>The positive rates of the urethra swabs and the prostatic fluid were 5.1% (11/215 ) and 2.0% (1/49), respectively. Nine cases in 11 of the patients' spouses (81.8%) were diagnosed as BV.</p><p><b>CONCLUSION</b>BV pathogen can attack and attach to the epithelia of male genitals to form clue cells. Clue cells positive, along with clinical symptoms, contribute to the diagnosis of male urogenital bacterial infection.</p>
