The Ticking of the Male Biological Clock

 Some biological clocks are obviously scarier than others

It’s an alarm, particularly for bachelors in their 30s. The male biological clock ticks, too, as delaying fatherhood could substantially harm a man’s chances of starting a family, says the study.

Earlier, researches had claimed that young women who put off starting a family till the late 30s or early 40s are less likely to become mothers. Now, a team in Europe has found that middle-aged men are almost a third less likely to conceive with their partner than males below 35. And the chance is significantly lower if a prospective father is over 40.

According to the researchers, the study could signal that men need to consider their age when planning a family as much as women do. This is because the older a man is the less chance his partner has of becoming pregnant.

“We found that by around the age of 40 men were starting to face serious problems,” lead researcher Prof Yves Menezo was quoted by The Daily Telegraph as saying.

The researchers claimed they reached the conclusion after analysing records of couples who had sought treatment for infertility at the Eylau Centre for Assisted Reproduction in Paris between January 2002 and December 2006.

The study involved a form of fertility treatment, where the sperm is “washed” before being inseminated into the woman. For men between 30 and 35, the successful pregnancy rate was 13.6 per cent. But that fell to 9.3 per cent if the man was older than 45, a decrease of almost a third. It also found that men over 35 were 75 per cent more likely to have their partner suffer a miscarriage.

Prof Menezo said there could be a number of reasons behind the findings, including that the DNA of sperms decays over time.
