AIM: Study microflora of urine, ejaculate, urethra scrape in normal state and infertility.MATERIALS AND METHODS: 2 groups of men were examined: I (28)--control, conditionally healthy men (20 - 25 years of age), II (26)--infertile patients (25 - 35 years of age). Middle portion of morning urine, ejaculate, urethra scrape were studied in group I, in II--ejaculate. Bacteriologic study of urine and ejaculate was carried out in an extended kit of nutrient media (HiMedia) for facultative- anaerobic (FAB) and non-clostridia anaerobic bacteria (NAB). Urethra scrape and ejaculate were studied by PCR in group I.RESULTS: In urethra scrape and ejaculate a wide spectrum of FAB and NAB was detected in group I. Corynebacterium spp. and coagulase-negative staphylococci (67.9% each) were the dominant cluster of FAB. Eubacterium spp.--in NAB. Bacteriologic study of ejaculate corresponded in PCR with similar results of dominating bacteria. Among FAB the same clusters dominated during bacteriologic study of ejaculate from group II patients, among NAB--Propionibacterium spp., Peptococcus spp. and Peptostreptococcus spp. Quantitative characteristics of ejaculate of group I and II differed insignificantly.CONCLUSION: The frequency of detection of certain genera of FAB and NAB was significantly higher in patients with infertility than in conditionally healthy men, however quantitative parameters of the isolated microorganisms practically did not differ between groups.
