Tick Tock Goes The Biological Clock
Posted by Clem Bastow on September 11, 2008
The idea of women having a ‘biological clock’ when it comes to having babies has long been a favoured punchline in the battle of the sexes (not to mention television situational comedy and chick lit). But is it a compelling reality (for some women) driven by, well, biology, or simply a societal pressure that has made its way into our collective subconscious? A group of NSW researchers seem to believe it’s the former:
The Garvan Institute of Medical Research is targeting professional Sydney women aged between 25 and 35, warning that maintaining a healthy lifestyle is not enough to preserve fertility, and IVF cannot be considered a fail-safe back-up plan.
Newtown gynaecologist Gabrielle Dezarnaulds said women have a fixed number of eggs to last them a lifetime and fertility drops sharply from the late 30s as the number and quality of eggs dwindle.
Success rates for assisted reproductive technology also decline the longer a woman’s biological clock has been ticking, she said.
“I’m not saying you should get pregnant before a set age, but go and chat to your GP, even if you’re not aiming to get pregnant immediately. Work out a time frame when you might start to, and if you are ready to have a baby, get on with it.”
Generally speaking, when research/opinions like these are aired, there is always a bristling amongst women (myself included) who sometimes feel it paints them as little more than baby factories who need to get cracking; the former Howard Government’s “one for you, one for the country” initiatives did little to ease these worries.
But is it worth considering what bearing waiting to have children may have on those of us who choose to have babies? There is something to be said about scientific (rather than societal) ideas of when the female body is most fertile. What are your thoughts on the issue – do you have a biological clock, and is it ticking?
