Research published in Molecular Psychiatry details how negative life experiences physically change men’s sperm.
People could be experiencing stress and trauma because their fathers did before they were conceived, Luke O’Neill has said.and details how life experience physically changes men’s sperm., Trinity Professor Luke O’Neill said 58 men had been involved in the study, all of whom had endured “various types of trauma” during their youth.“They measured their sperm and saw their sperm had been marked in a different way because of the childhood trauma.
“The question now is, will those marks pass onto the next generation when the sperm fertilises the eggs. Two of the genes that were marked were tied into brain development. “So, you can imagine, if that goes into foetus, the baby’s brain might develop differently and increase the risk of having stress or trauma - you never know.”Prof O’Neill said there are a number of other environmental factors that can negatively impact on the development of a baby.“Mothers who were malnourished, their offsprings were at higher risk of diabetes, of heart disease and of schizophrenia for years.”There are also good reasons why women are advised not to smoke or drink while pregnant.
