This is the report of a genital tract infection caused by Arcanobacterium haemolyticum in an infertile man from Venezuela.

Laboratory analysis showed leukocytospermia, low sperm count, motility and vitality, without abnormalities in hormonal profile. Sperm culture was positive for A. haemolyticum. After erythromycin therapy an improvement in some sperm parameters was observed. A. haemolyticum could be considered as a cause for silent seminal infection
