Are Older Fathers More At Risk of Having Children with Autism?

New autism studies confirm genetic complexity and risk for older fathers. Four new studies recently published observed the genetics of autism and found further evidence that older fathers are at increased risk of having an autistic child. This suggests that the genetic roots of the condition are incredibly complex.

One study found that the mutations were four times more likely to occur in fathers and the risk for men began increasing at age 35. The reason be may be because the older men are, the more times their sperm-creating cells have copied themselves, and each time a cell is copied, there is a chance that a mutation will occur. Studies that have been published previously found that men over 50 have twice the risk of having an autistic child, compared with those under 30, and the odds are four times greater for those over 55.
