  1. *Denotes a statistically significant difference (P < 0.0001) between total methylated CpG sites for a given DMR between high and low fertility spermatozoa. n = the number of clones sequenced
  2. The DMRs identified on chromosome 12 and chromosome 19 were assessed for differential levels of methylation by bisulfite conversion followed by Sanger sequencing
