According to a new article published in respected journal Nature, men who father children later in life are more likely to have offspring with genetic mutations which can provoke schizophrenia, autism, and other afflictions.
Study author Kari Stefansson, geneticist and neurologist at the University of Iceland, told Reuters in an interview: “Conventional wisdom has been to blame developmental disorders of children on the age of mothers,(but) our results all point to the possibility that as a man ages, the number of hereditary mutations in his sperm increases. It is the age of fathers that appears to be the real culprit.
According to the results found in the experiments and data, researchers found that there are approximately two genetic mutations occurring in children for every year of increase in a dad’s age.
Studies that have taken place in the past also seem to confirm these findings. For example, one study claims that men who fathered children when they were over 40 years of age were six times more likely to have an autistic child than fathers who were under 30.
Children’s disorders linked to the age of the mother include Down’s syndrome and pregnancy tends to be more difficult the older the mother is. Doctors recommend plenty of pre-natal check-ups with more being scheduled during the last two months of pregnancy in order to ensure the optimal health of the mother and baby.
