The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism（孤獨(dú)癥）

2、 and psychiatric disorders. ? With age, sperm-producing cells do not copy a man's DNA as effectively, leading to genetic mutations. ? Martin Fielder, an anthropologist（人類學(xué)家） at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutatio

3、ns per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. ? 'The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap.' ? In contrast, women

4、pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. ?

7、opmental disorders that have a lifelong effect on someone's ability to interact socially and communicate. ? In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. ? Researchers said men should be advised

8、about the potential problems in order to help their personal decision-making when it came to having fathering children at older ages. ? They warned that advancing paternal age posed a risk of 'numerous public health and societal problems'. ? Among well-known older dads are Simon Cowell, 54, whose son was born earlier this month, and comedian Frank Skinner whose first child was born in 2012 when he was 55.
