Kids by Older Men Less Intelligent?

[pioneer]

Children fathered by older men are likely to be less intelligent than the offspring of younger dads, Australian and US scientists found in a report published Tuesday.

The research contrasted sharply with earlier studies showing that older mothers produced children more likely to record above average intelligence scores, the researchers concluded.

Lead scientist John McGrath, from the Brisbane-based Queensland Brain Institute, said the result was a world first and had implications for men in Western societies who have delayed fatherhood until their 40s or older.

"The offspring of older fathers show subtle impairments on tests of neurocognitive ability during infancy and childhood," he said in the new research. - source: Agence France-Presse

Ang sperma medyo sagulan na ug ihi kay, medyo luag naman.

ps
kidding aside, the sperms of older men are of lesser quality, than the younger ones. Remember that sperm donors are mostly on their primes.

This article is correct.

As men age, the rate of division and gametogenesis increases as age increases; this can lead to chromosomal non-dysjunction, which can lead to a mosaic of autosomal recessive/dominant diseases and conditions.

Just be careful.

If both potential mother and father are at risk; it is best to follow the advice/wise counsel of your Gynecologist/Obstetrician.

Make sure to enroll in Gene Testing to see if the child is at risk for certain diseases
