Table 2 Correlation analyses between sperm DNA integrity tests and conventional semen evaluation parameters

From: Could high DNA stainability (HDS) be a valuable indicator of sperm nuclear integrity?

Correlations N = 375 Sperm DNA fragmentation (TUNEL) DNA fragmentation index (DFI) High DNA Stainability (HDS) Protamine deficiency (CMA3)
Semen volume [ml] 0.09 0.11b −0.07 −0.09
Sperm concentration [106/ml] 0.01 −0.04 −0.09 − 0.22a
Sperm abnormality morphology [%] 0.02 0.05 0.16a 0.27a
Sperm abnormal head [%] 0.03 0.06 0.17a 0.25a
Total motility [%] −0.11b −0.17a −0.12b − 0.11b
  1. TUNEL Terminal deoxynucleotidyl transferase dUTP nick end labeling, CMA3 Chromomycin A3
  2. a Correlation is significant at the 0.01 level (2-tailed)
  3. b Correlation is significant at the 0.05 level (2-tailed)
