Would-be fathers warned not to wait beyond 45

  • Comment

Men in their early 40s who wish to have children should not be advised to delay by health professionals, experts have said.

Even leaving fatherhood to age 45 compared to 41 could influence a man’s ability to father a child, according to a new study.

Experts at the Huntington Reproductive Medicine Centre in Brazil found that the chance of fathering a child fell by 7 per cent for every year above the age of 41.

The results showed that a man’s age had “a significant impact” on the chance of a couple conceiving.

For fathers aged around 41, the chance of achieving pregnancy in IVF was about 60 per cent. But this fell to about 35 per cent in the group where men were aged around 45.

The researchers suggested the pregnancy rate may fall off at an even faster rate for men over 45.

Dr Paula Fettback, who presented the findings at the American Society for Reproductive Medicine conference in Orlando, said men should not delay fatherhood.

She said: “Men around the age of 40 should not wait too long - age counts. Men also have a clock - it’s not the same as it is for women - but men cannot wait forever.

“Definitely after 45, if they have not thought about having children, they need to think about it.”
