In 2008, Brad Van Voorhis, head of the fertility clinic at the University of Iowa, decided he wanted to measure how well children conceived through in vitro fertilization do on intelligence tests, hoping to dispel lingering concerns about their cognitive abilities. So he and his team compared the standardized-test scores of 463 IVF kids ages 8 to 17 against the scores of other kids in their classes. They found that the IVF kids scored better overall and in every category of test—reading, math, and language skills. And they found that the older the mother, the better the kid performed.
Van Voorhis guesses that the children of older mothers outperform their peers because the mothers, who’ve waited so long to have them, are more engaged. It’s a recipe for success: “Fewer kids at home, more attention to the kids they do have, and more money to devote to their education.” Other studies corroborate these findings. In research published in the journal Fertility and Sterility in 2007, Richard Paulson, head of the fertility program at the University of Southern California, found that mothers in their fifties reported less parental stress than those in their thirties and forties, the same level of mental functioning, and the same perception of fatigue. The fiftysomething women in his small national sample, incidentally, were also less likely than their counterparts to employ a nanny. They are more checked in.
