“Delaying fatherhood may offer survival advantages, say US scientists who have found children with older fathers and grandfathers appear to be “genetically programmed” to live longer.
The genetic make-up of sperm changes as a man ages and develops DNA code that favours a longer life – a trait he then passes to his children.
The team found the link after analysing the DNA of 1,779 young adults…
Although delaying fatherhood increases the risk of miscarriage, the researchers believe there may be long-term health benefits.
Inheriting longer telomeres will be particularly beneficial for tissues and biological functions that involve rapid cell growth and turnover – such as the immune system, gut and skin – the scientists believe.
And it could have significant implications for general population health.”
