Fig. 1From: Sperm function, mitochondrial activity and in vivo fertility are associated to their mitochondrial DNA content in pigsHeat map of Pearson correlation coefficients (r) between mitochondrial DNA content (mtDNAc) and sperm function parameters (sperm viability, motility, and kinematic parameters). n = 22. The presence of the r value in a cell indicates statistically significant correlations (P < 0.05)Back to article page
