Mestrovic T, et al. - A scrutiny was carried out of the effects of Corynebacterium glucuronolyticum (C. glucuronolyticum) on a range of sperm quality parameters. Although it was rarely encountered as a monoisolate in significant quantities, C. glucuronolyticum could exhibit a negative effect on certain sperm parameters. Hence, its consideration was required in the microbiological analysis of urogenital samples.
