Sperm DNA Fragmentation Index and Hyaluronan Binding Ability in Men from Infertile Couples and Men with Testicular Germ Cell Tumor

Figure 2

The proportion of men with a normal and increased DNA Fragmentation Index (DFI) and normal and decreased Hyaluronan Binding Assay (HBA) results of 312 patients from infertile couples (blue circles) and 23 patients with germ cell tumor (TGTC) (red circles). The vertical line corresponds to 80% of HA-bound sperm cells. The horizontal line corresponds to 30% of sperm with DNA fragmentation.
