Fig. 2From: Sperm function, mitochondrial activity and in vivo fertility are associated to their mitochondrial DNA content in pigsCorrelation matrix of (A) mitochondrial membrane potential (MMP) and (B) intracellular superoxide levels (superoxides) in sperm with their mitochondrial DNA content (mtDNAc) and total motility (TMOT). Pearson correlation coefficients (r) and P-values correspond to the correlation between each mitochondrial-associated parameter (i.e., MMP and superoxide levels) and mtDNAc in sperm. n = 22Back to article page
