Fig. 3From: Sperm function, mitochondrial activity and in vivo fertility are associated to their mitochondrial DNA content in pigsMean and standard error of the mean (SEM) of (A) in vitro fertility parameters (fertilisation rate and embryo development) and (B) in vivo fertility outcomes (conception rate and farrowing rate) between sperm samples classified as having low or high mitochondrial DNA content (mtDNAc). n = 22 for in vitro fertility outcomes and n = 13 for in vivo fertility outcomes. *P < 0.05Back to article page
