Sperm epigenetic programming is tailored to meet the need of this specialized cell,
which include its interaction with the oocyte during fertilization and early embryo
development. The unique nature of the sperm epigenome has resulted in multiple studies
investigating how perturbations in epigenetics might impact male fertility and early
embryo development. In addition, sperm epigenetics appear to be altered by specific
environmental exposures, which could provide a link for investigating the role of
these triggers in somatic health of off springs produced. This has the potential of
explaining otherwise missing heritability factors seen with several diseases. While
this field of investigation is new and with limited validation, it is intriguing and
further studies are warranted.
