Longevity & AgingHow Older Parents May Shape Their Children’s Aging Trajectories
Could the age of a mother or father influence how their children age? This review brings together animal research and human population studies to explore that possibility. It defines advanced parental age as 35 or older for mothers and 40 or older for fathers. The author examines declining egg quality, sperm DNA damage, and changes in how genes are switched on or off. These mechanisms may connect parental aging with offspring metabolism, behavior, lifespan, and susceptibility to brain diseases. However, the abstract provides no numerical risk estimates or evidence that changing reproductive timing prevents these outcomes. The proposed “intergenerational clock” is a scientific framework, not a clinical test or a prediction for individual families. This summary is based on the abstract only.
