Review links advanced parental age to offspring aging via epigenetic inheritance
This abstract reviews how advanced parental age (≥35 in mothers, ≥40 in fathers) may shape offspring aging through epigenetic changes, drawing on animal models and human cohorts. [1]
Automatic summary · not editorially reviewed
The key findings
The abstract defines advanced parental age as at least 35 years in mothers and at least 40 years in fathers. [1]
The review integrates evidence from Drosophila, mammalian models and human cohorts. [1]
Age-related DNA methylation, histone and non-coding RNA changes are proposed as main mediators acting during early embryogenesis. [1]

Review scope: parental age and offspring healthspan
This review addresses delayed parenthood as a demographic trend and asks how advanced parental age (APrA) affects offspring. The abstract defines APrA as at least 35 years in mothers and at least 40 years in fathers. It states that APrA has been linked to higher risks of congenital anomalies, premature mortality, neurodevelopmental and metabolic dysfunction, and neurodegenerative diseases in offspring. The authors frame this as an "intergenerational clock" connecting reproductive timing to aging across generations.

Maternal and paternal factors plus cross-species evidence
The review separates maternal factors, such as declining oocyte quality, from paternal factors, including sperm DNA fragmentation. It integrates evidence from fruit flies (Drosophila), mammalian models and human cohorts. According to the abstract, offspring of older parents in these studies show distinct behavioral phenotypes, including social deficits and anxiety, alongside reduced metabolic vitality.

Proposed epigenetic mechanism and its stated limits
The abstract proposes age-related changes in DNA methylation, histone profiles and non-coding RNAs as main mediators that influence gene regulation during early embryogenesis. These processes are said to interact with parental lifestyle and environment and to be passed on through intergenerational inheritance, raising susceptibility to neuropsychiatric and neurodegenerative disorders. The authors present this as a framework for reproductive counseling and public health, not as proven causation.

How to interpret this
This is an abstract only; the full text was not reviewed. The abstract reports no study design, sample sizes, follow-up or effect estimates for the cited cohorts and models. It describes proposed mechanisms and associations, not proven causation, and does not establish that parental age directly causes offspring disease.
