Recent pilot studies with limited sample sizes have implicated a role for the microbiome in male fertility. Here, we aimed to identify seminal and urinary microbiota that may contribute to the etiopathogenesis of abnormal SA parameters. METHODS: Men presenting for fertility evaluation or for vasectomy consultation with proven biological paternity were recruited. Clinical data, semen, and urine were collected. Participants were then stratified according to alterations in SA parameters. Samples underwent 16S rRNA sequencing followed by taxonomic microbiome community profiling. RESULTS: 73 participants were included in the study and were stratified based on alterations, or lack thereof, in SA parameters. Men with impaired sperm motility (N=27) showed a three-fold higher abundance of semen L. iners (p=0.046) and an almost fifty-fold higher abundance of urine D. micraerophilus (p=0.032) compared to men with normal sperm motility (N=46). These relationships persisted on canonical correlational analysis (L. iners: r=0.39, p=0.011; D. micraerophilus: r=0.44, p=0.014; Figure 1). Men with abnormal sperm concentration (N=20) showed a higher abundance of semen P. fluorescens (p=0.010) and semen P. stutzeri (p=0.024), but a lower abundance of semen P. putida (p=0.005), urine E. faecalis (p=0.012), and urine S. aureus (p=0.037), compared to men with normal sperm concentration (N=53). CONCLUSIONS: Our findings highlight a critical group of seminal and urinary microorganisms associated with abnormalities in sperm motility and concentration. These data support findings from previously published, smaller studies, while also providing target microorganisms for future mechanistic investigations into the complex relationship between the microbiome and male infertility.
