    Compared to its female counterpart, the microbiota of the male genital tract has not been studied extensively. With this study, we aimed to evaluate the bacterial composition of seminal fluid and its impact on sperm parameters. We hypothesized that a dysbiotic microbiota composition may have an influence on sperm quality. Semen samples of 26 men with normal spermiogram and 68 men with at least one abnormal spermiogram parameter were included in the study. Samples were stratified based on total sperm count, spermatozoa concentration, progressive motility, total motility and spermatozoa morphology.

Spermiogram, semen culture, and sperm transmission electron microscopy TEM analysis were performed. TEM data were elaborated using a mathematical formula that calculates a fertility index FI —able to define patients as fertile or infertile—and the percentage of sperm apoptosis, immaturity and necrosis. We aligned the amino acid sequence of beta-tubulin with protein of the most frequent species isolated from semen.

    Semen culture and the assessment of genitourinary tract infections

    Key words: male genital tract infection, sperm parameters, antibiotic therapy, sperm agglutinating antibodies, leukocytospermia. Bacteriological etiology was investigated in 29 infected asymptomatic infertile males. The localization of the infection and the effect of a long term antibiotic therapy on semen parameters were evaluated. The most frequent etiological agent isolated was Enterococcus faecalis. Positive bacteriological culture was obtained in prostatic fluid in 16 patients and in semen in
