Bacteriospermia-Related Male Infertility: A Case Report on Diagnostic and Therapeutic Approaches

Abstract

Male infertility is significantly affected by bacteriospermia, defined by the presence of bacteria in semen. This case report aims to address the effects of bacteriospermia and its correlation with semen characteristics, sperm DNA fragmentation (SDF), and reproductive outcomes. The 33-year-old male was diagnosed with bacteriospermia caused by two gram-negative bacteria: Escherichia coli and Klebsiella pneumoniae . It was found that sperm parameters such as mobility, number, and morphology were compromised in sperm, indicating poor fertility. In addition, SDF analysis has revealed a high DNA fragmentation index (DFI), emphasizing the detrimental effects of bacteriospermia on the integrity of sperm. Antibiotic therapy and antioxidant supplements have been used as therapeutic measures to reduce the impact of bacterial infections and DNA damage caused by oxidative stress (OS). Follow-up assessments showed significant improvements in the integrity of the sperm DNA and the resolution of microbial colonization, which ultimately led to successful in vitro fertilization (IVF) and embryo transfer (ET), leading to a positive pregnancy outcome.
