Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Sperm DNA fragmentation index (DNA Fragmentation Index, DFI). Timepoint: Baseline (before the first dose); after 10 weeks of daily probiotic supplementation (post-final dose). At each time point, semen samples are collected after 2 to 3 days of sexual abstinence. Method of measurement: Sperm DNA Fragmentation Index (DFI) is measured using the Sperm Chromatin Dispersion (SCD) assay with a commercial kit according to the manufacturer’s instructions. At least 300 spermatozoa per sample are assessed and the percentage of sperm with fragmented DNA is calculated. | — |
