March 9 (Bloomberg) — Children of older fathers have lower intelligence scores than those born to younger men, perhaps because of cumulative damage to men’s sperm during their lives, Australian and U.S. researchers found.
Children born to fathers who were age 20 scored an average of 2 points higher on an IQ test than children born to 50-year- old fathers, according to the study of data collected on 33,437 children from 1959 through 1965. Average IQ among children dropped steadily on a number of tests as their fathers’ ages rose, according to the research published today in Public Library of Science, Medicine, an online journal.
