A study has investigated the influence of phthalate exposure on sperm epigenetics, embryo development, and whether DNA methylation in sperm cells may be a path by which a father’s environmental exposure influences these endpoints.
Phthalates are chemicals used to make plastics more flexible and harder to break. Some phthalates are also used in personal care products such as shaving cream.
The study is still ongoing but from their first samples, the results indicate that a father’s environmental conditions may influence epigenetic reprogramming, influencing early-life development.
