Propionibacterium acnes in urine and semen samples from men with urinary infection.

Objective: Propionibacterium acnes has been implicated in the pathogenesis of prostate disease as acute and chronic prostatic inflammation, benign prostatic hyperplasia and prostate cancer although it should still be clarified if Propionibacterium acnes (P. acnes) is a commensal or accidental prostate pathogen. Aiming to evaluate the pathogenic potential for genitourinary tract of Propionibacterium acnes, we investigated the frequency of P.

Molecular evidence of apoptotic pathway activation in semen samples with high DNA fragmentation.

Background/aim: Male infertility is diagnosed by semen parameters, such as concentration, motility and morphology; however, these are not sufficient for the prediction of male fertility capacity. In the clinical routine, several other sperm functions have been introduced, including the sperm DNA fragmentation test. The objective of the present study was to evaluate sperm chromatin integrity in semen samples.
