Paternal age effect



The paternal age effect describes the influence that a father's age has on the chances of conferring a genetic defect to his offspring. Generally, older men have a greater probability of fathering children with a genetic defect than younger men do.[citation needed] This is seen as likely due to genetic copying errors which may increase in number after repeated spermatogenesis cycles over a man's lifetime.

Disorders correlated with paternal age

Achondroplasia (dwarfism); craniofacial disorders such as Apert syndrome and Crouzon Syndrome; mental retardation of unknown etiologies; autism; and 25% of schizophrenia cases are correlated with advanced paternal age.
