NCT05328999

Brief Summary

With this study, the investigators want to investigate the microbiome and human papilloma virus (HPV) status of couples with subfertility. The investigators want to gain information about association of female and male microbiome and its impact on fertility. HPV prevalence is high, and its impact on fertility has not been studied intensively. The investigators want to find out whether there is an association between HPV status and subfertility, vaginal and seminal microbiome and HPV status and the prevalence among our subfertile couples. As part of this study, the investigators will perform a randomized placebo controlled double blind pilot study to investigate the association between altered sperm quality (impaired motility and elevated DNA fragmentation index), the seminal microbiome and whether intake of probiotics alters these parameters.
