WebOct 8, 2024 · An increasing body of epidemiological study supports that paternal stress induced by environmental exposures and lifestyle can modulate the sperm epigenome (including histone modification, DNA methylation, and noncoding RNA expression), sperm-egg fusion, embryo development, and offspring health. WebThe methylation of the maternal genome is maintained until the two-cell stage [19,20]. Single-cell epigenome sequencing results show that the median level of sperm methylation undergoes a significant decrease from 80.3% to 38.3% shortly after fertilization. Meanwhile, the maternal genome also shows mild demethylation from 32.4% to 27.8% [21].
