genital tract infection in asymptomatic infertile men and its effect on semen quality

male urogenital tract infection plays an important role in men infertility. asymptomatic bacteriospermia has been paid attention as a major cause of male infertility. the aim of this study was to microbiological investigation of semen sample of infertile men attending to infertility clinic and evaluation of the effects of bacteriospermia on semen quality. eighty eight infertile men were evaluated by standard bacterial culture method. standard semen analysis was performed according to who guidelines. among total cases, 35.22% (31 cases) showed at least one pathogen: 10.22% e.coli, 9.09% coagulase negative staphylococci (saprophyticcus), 6.81% group b streptococci, 5.88% entrococci, 5.68% candida sp., 2.27% gonococci, 2.27% staphylococcus aureus, 1.13% klebsiella sp. and 1.13% providencia sp. there was a significant relation between the bacteriospermia and the rate of no motile and morphologically abnormal sperms (p 0.05). it seems that leukocytospermia is a poor marker to predict bacteriospermia.
