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.

Study Arms (2)
Subfertile patients
Males and females between 18 and 50 years of age with subfertility presenting at the fertility center at the Medical University of Graz.
Subfertile males with elevated DNA fragmentation index and asthenozoospermia

Interventions
As intervention in the randomized placebo controlled double blind trial, 30 males will receive either probiotics or placebo once daily for 3 months. Sperm count and microbiome analysis before and after intervention will be performed.
