There’s plenty things in life that are relative; but not when it comes to fertility, apparently. Here is the golden age—according to cold, hard stats—that you should be trying for a family.
A new computer model has revealed the age couples should begin trying to conceive, the number statistically staggered according to whether they plan to have 1, 2, or 3 children.
300 years of fertility data has shown that for a one baby family, 32 is prime time for 90% chance success—without IVF. For three babies, the age is reversed—23—for the same odds.
For ease of planning, the model also stipulates the spacing between pregnancies for optimum success: couples should “start trying for the next pregnancy 15 months after the birth of a child”.
Obviously, the computer’s predictions are generated from averages, so the more personal nuances, and unique physiological differences, among those thinking about a future family aren’t part of the equation.
The fact remains, however, that fertility isn’t a permanent fixture in our lives.
Explains Allan Pacey, professor of Andrology at the University of Sheffield: “What it is saying is that if you’re relaxed about having three children, you can wait until you’re 35, but you’ve got to start early to be certain.”
