Children of older fathers have higher risk of mental illness

For so long, mothers – particularly older moms — bore the brunt of responsibility for genetic disorders in their children. And for good reason. Eggs are stockpiled from birth, not made anew with each monthly reproductive cycle, so eggs stored for decades until childbearing can develop genetic mutations. The older the mother, the greater the chance of abnormalities that can contribute to conditions such as Down syndrome, especially after age 35. Fathers, on the other hand, constantly make sperm, so their reproductive contribution was supposed to be fresher and free of accumulated DNA damage.

That may not actually be the case, however, according to the latest study in JAMA Psychiatry investigating how advanced paternal age can affect rates of mental illness and school performance in children.
