Summary
This narrative review synthesises current evidence on how paternal lifestyle factors—including diet, stress exposure, and environmental toxins—may be transmitted to offspring through alterations in sperm DNA methylation. As suggested by the literature reviewed, such epigenetic inheritance mechanisms could represent a pathway through which paternal health behaviours influence offspring development and disease risk, independent of genetic sequence variation. The paper contributes to understanding transgenerational inheritance beyond classical genetics, though the clinical significance and reversibility of such effects remain areas of active investigation.
Regional applicability
The findings are relevant to UK public health and preconception counselling frameworks, particularly regarding paternal nutrition and lifestyle guidance. However, translating mechanistic evidence from animal models and human observational studies into clinical recommendations requires further validation in UK populations and consideration of healthcare system context.
Key measures
DNA methylation patterns in sperm; paternal lifestyle and environmental exposures (diet, stress, toxins); offspring health and developmental outcomes
Outcomes reported
The study examined how paternal lifestyle factors and environmental exposures are inherited by offspring through alterations in sperm DNA methylation patterns. The research synthesises evidence on the mechanisms by which paternal diet, stress, toxin exposure, and other lifestyle variables affect epigenetic marks on sperm that influence offspring phenotype and health outcomes.
