But the study does not break down the couples' ages and explain how that might have impacted their IVF success rate, noting only that they ranged in age from 25 to 47 with an average age of 36. Nor does it detail how long the embryos were observed in culture before being transferred into the womb, instead indicating that they were "cultured until 5 or 6 days" after fertilization. And while the study does suggest that technology can help in the embryo selection process, experts say the decision to undergo IVF and the odds of being successful vary from couple to couple.
"Obviously, the goal is to pick out the best embryos, and this study is certainly not the first to look at this technique," said Goldfarb, explaining how similar studies have found mixed results. "It's something still in play, and we'll how this sorts out in long run.
"But I think the one thing patients want to hear is your best assessment of their individual chance of getting pregnant," he added. "And you can get a pretty good estimate of that based on their age and some other characteristics."
