Older fathers made headlines several years ago when researchers at the Mount Sinai School of Medicine reported that a man over 40 is almost six times as likely as a man under 30 to father an autistic child. Since then, research has shown that a man's chances of fathering offspring with schizophrenia double when he hits 40 and triple at age 50. The incidence of bipolarity, epilepsy, prostate cancer and breast cancer also increases in children born to men approaching 40. (...)

A 2009 study at the University of Queensland, Australia, found a correlation between advanced paternal age and poorer performance by children on intelligence tests (the children of older mothers actually performed better).
