Infections and Male Infertility

Presence of aerobic microorganisms and their effect on the basic parameters of sperm in infertile men. Urinary tract infections in men are a very important etiological factor of infertility. In a recent prospective study, 72 patients with abnormal sperm parameters were examined. The analysis of the sperm was performed according to the instructions of the WHO, while at the same time a microbiological test was performed by a bacteriological aerobic culture, a test for the detection of chlamydial antigen, a culture for Candida sp., and special cultures for ureaplasma and mycoplasma. Overall, 70% of the sperm samples were positive for at least one microorganism. Ureaplasma was the most common microorganism and was found in 33% of sperm samples of infertile patients. The next most common microorganisms were Enterococcus faecalis (Enterococcus) (12.5%) and Escherichia coli (12.5%), followed by Staphylococcus aureus (7%), Chlamydia trachomatis (7) %), and the yeast Candida sp. (5.6%). However, no statistically significant correlation was found between the presence of aerobic microorganisms in the sperm and the basic parameters of the sperm, i.e. volume, pH, concentration, total number, motility, vitality, and morphology of the spermatozoa.
