ARE ALL KINDS OF AUTISMS AND SCHIZOPHRENIAS ON THE RISE BECAUSE MEN ARE FATHERING BABIES IN THEIR MID 30s AND BEYOND, WAY BEYOND?

New Key to Autism

Convincing Evidence

What Causes These Genetic Errors?
Should Older Men Stop Fathering Babies?
A study published in the September, 2006 issue of the Archives of General Psychiatry may give older prospective fathers pause before plunging into biological parenthood. The authors found a significant increase in the risk of autism and similar disorders as fathers got older


This is not the first discovery of its type. Healthcare professionals have long known that as parents age, the risk of giving birth to a child with certain illnesses goes up. Older mothers, for example, are more likely to have a child with Down syndrome. In recent years, studies have revealed a link between aging fathers and schizophrenia.

Until recently, health care professionals have focused almost exclusively on the mother's age as a risk factor for health problems in the child. But we now know that the father's age also adds to the risk of potentially devastating diseases. And there is no practical way to detect these illnesses during pregnancy. For those weighing the risks, the decision can be wrenching. Adoption and in some instances a sperm donation may be acceptable alternatives to older fathers wanting to build a healthy family.
