Fig. 1From: Could high DNA stainability (HDS) be a valuable indicator of sperm nuclear integrity?Correlations analysis between TUNEL, DFI, HDS and CMA3 assays. DFI versus HDS (upper left graph). TUNEL versus HDS (upper right graph). CMA3 versus HDS (lower left graph). DFI versus TUNEL (lower right graph). TUNEL: Terminal deoxynucleotidyl transferase dUTP nick end labeling, CMA3: Chromomycin A3; HDS: high DNA stainability; DFI: DNA fragmentation indexBack to article page
