The average age of fatherhood is increasing in the US and in Western Europe. Some research shows that offspring of older fathers are at increased risk for diseases and conditions (Bray et al., 2006). Some experts predict an upswing in cases of schizophrenia will accompany the increasing average paternal age. “The actual percentage of cases with paternal germ line-derived schizophrenia in a given population will depend on the demographics of paternal childbearing age, among other factors. With an upswing in paternal age, these cases would be expected to become more prevalent” (Malaspina et al., 2006). Approximately 25-33% of all cases of schizophrenia may be due to the father’s age at conception, according to Malaspina (2006). Malaspina sees a connection between advancing paternal age and neural functioning difficulties in people with autism and with schizophrenia. According to Tarin et al. (1998), there are well over 30 known conditions that the offspring of older fathers are more at risk for (see chart on paternal aging in the linked article).

Please read the rest of my article if a way of preventing some non-familial, sporadic autism is of interest.

Other conditons have also been found to be linked to increasing paternal age:
