Results of SCSA and SCD for four samples (2021A, 2021B, 2022A and 2022B). The 25th and 75th percentiles are represented by boxes, with the median value, while the 10th and 90th percentiles are represented by whiskers. DFI, DNA fragmentation index; SCSA, sperm chromatin structure assay; SCD, sperm chromatin dispersion
