Blastocyst transfer and Time lapse technology
Time lapse technology / morphokinetics in Embryology Reading all the literature and references I come to a conclusion that , the end point of any Time lapse technology in embryo culture is getting a blastocyst, or blastocyst is the end point if any Time lapse technology , may be it Embryoscope or something else. As we are doing 100 % blastocyst transfer since 8/9 years , if we get a day 5/6 blastocyst for particular couple, then it is obvious that this embryo is competent enough to reach that stage. It is survival of the fittest. The problem occurs when the centre transfer day 2/3 embryos. There may be multiple embryos on day 2/3, but which is going to survive ,very difficult to assess. All may look similar, but when they are put to the challenge to make their own food and survive onwards without maternal support ( called embryonic genome activation), then many of them wither. As they look similar, the clinician “may” transfer the withering one. Here, the Time Lapse technolog
