I came across this information on Elsa Elsa blog and thought it too interesting not to share it with my readers also.
“Women approaching middle age have long been aware that the consequences of a ticking biological clock include not only decreased fertility but also a sharp increase in the odds of delivering a child with Down syndrome. Older men, seemingly untouched by such biological constraints, felt free to father children as they entered middle, and even old, age.
But now it is becoming increasingly clear that the biological clock ticks for men as well as women, as researchers turn up evidence that as would-be fathers get older, they have an increased chance of passing on genetic defects to their children.”
“Children are almost twice as likely to die before adulthood if they have a father over 45, research has shown.
A mass study found that deaths of children fathered by over-45s occurred at almost twice the rate of those fathered by men aged between 25 and 30.
Scientists believe that children of older fathers are more likely to suffer particular congenital defects as well as autism, schizophrenia and epilepsy. The study was the first of its kind of such magnitude in the West, and researchers believe the findings are linked to the declining quality of sperm as men age.”
