Adverse Childhood Events (ACEs) or childhood stress has been linked to the development of impaired health conditions. But did you know that a man’s sperm cells can carry traces of childhood stress?
The study of epigenetics looks at the manner in which lifestyle alters how our genes behave. A recent study identified that fathers exposed to high stress in childhood had different epigenetic markers that may affect their offspring.
The new research, published Jan. 3 in the journal Molecular Psychiatry, looked at the “epigenetics” of the sperm cells of fathers who had been exposed to high stress in childhood.
Epigenetics involves how DNA — the blueprint used to build the proteins and molecules that make up our bodies — is read. Epigenetics doesn’t change DNA’s underlying code but rather alters which genes can be switched on. Research suggests that people’s life experiences and environments can leave these “epigenetic changes” on DNA, which can then modify gene activity.
It is not only childhood stress that affects male sperm but also stresses throughout adult life. The epigenetic alterations that occur to the DNA contained in male sperm have been linked to inter-generational genetic changes.
One major area often affected by epigenetic changes is methylation. While there are a number of genes involved in methylation, knowing which ones have been switched on or off, can guide nutritional support which may help prevent flawed gene activity. This is an area of expertise and should always be considered in conjunction with a qualified health professional.
In my book I briefly explain the concept and mechanism of methylation, but it is a complex scenario. I also encourage people seeking to become parents to invest in a quality and reputable DNA test.
