I happened to come across one article from CNA’s website that said that children fathered by older men are likely to be less intelligent compared to those children who had younger dad.
The researchers examined data collected on 33,000 children in US between 1959 and 1965 fathered by men aged from 15 to 65. They found that the children of older dads performed less well in intelligence tests conducted at age eight months, four years and seven years.
Children with older fathers also have an increased risk of health problems in their children, including schizophrenia, autism, dyslexia, epilepsy and dwarfism.
I supposed this is another reason for early marriages and to have kids at a younger age.
