A study reported in Health Day News revealed that a man's age could affect the intelligence and the resulting child health. This is due to genetic changes or mutations on chromosome men as they age. It is possible that the father inherited DNA changes that affect intelligence in children and the health of the child.
The researchers noted that the older age of the mother during pregnancy may increase the risk of intellectually handicapped children, such as Down syndrome. Apparently it is not only a risk to be concerned about women, because men with older age have the same risk level. But how the genetic mutation that occurs in men still can not be explained.
"In many cases the fathers, on average, they (the father having a child with an intellectual disability) two years older than the fathers who have children without intellectual disabilities," said Jayne Hehir-Kwa, chairman of the department of human genetic research , University of Nijmegen, the Netherlands told Health Day News.
Children with an IQ of less than 70 usually have a genetic mutation. They also tend to have congenital heart defects and other health problems. In the cases studied, 70 percent of DNA abnormalities associated with children with intellectual disability revealed by the father.-Vemale.com
