an abnormal number of chromosomes embryos that would likely fail to implant in the womb or result in a miscarriage none of the embryos deemed the least healthy by the timelapse technique resulted in a pregnancy or a live birth according to the study in some ways its more of a negative to get pregnant and miscarry said goldfarb that rollercoaster can be much more traumatic than not getting pregnant at all 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 its something still in play and well 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
