Traditional morphology examination compared to time-lapse-based morphokinetic examination. During the traditional microscopic evaluation, the embryologists miss developmental events and stages because they check the embryos once a day (dots … mean the missed/not seen developmental stage). On the other hand, the time-lapse system makes a recording every 10 min, which provides a continuous follow-up.
