Identification and characterization of anaerobic bacteria in human semen: A retrospective study.

This study analyzed retrospectively 291 semen samples, identifying diverse anaerobic bacteria, mainly Prevotella (49 % of all isolates), Veillonella, and Peptoniphilus. Most isolates were susceptible to amoxicillin/clavulanic acid, suggesting its therapeutic potential in male infertility. Resistance to metronidazole was observed in Peptoniphilus, Veillonella, and Propionimicrobium, while Bacteroides exhibited resistance to benzylpenicillin.
