Male Urogenital tract infection plays an important role in men infertility. Asymptomtic bacteriospermia has been regarded as of the contributing factor to male infertility. In this study, 87 semen samples of infertile men attending the Human Reproduction Research Programme and Invitrofertilization unit (HRRP/IVF) of University Benin Teaching Hospital were evaluated Bacteriologically using standard Bacterial culture method. Standard semen analysis was performed according to WHO guidelines. Among the total cases, 36 (41.4%) showed at least one pathogen. Staphylococcus aureus (16.1%), Staphylococcus Saprophyticus (9.1%), Escherichia Coli (6.9%) Proteus mirabilis (3.4%) Klebsiella spp (2.3%) Pseudomonas aerouginosa (1.1%) and Proteus vulgaris (2.3%). There was a significant relation between bacteriospermia and the rate of number of total motility and morphologically abnormal sperms (p < 0.0001.) The quality of sperm motility was significantly decreased in contaminated semen. The percentage of morphologically normal sperm was lower in this study. Staphylococcus aureus Staphylococcus saprohyticus and Echerichia coli were the most common pathogen with negative effects on sperm motility and morphology in this study. Moreover presence of bacterospermia and Leukocytospermia did not correlate with each other (P > 0.05). It seems that leukocytopermia is not a good maker to predict bacteriospermia.
