Objective: To compare pregnancy outcomes between the transfer of PGT-A tested completely hatched blastocysts versus tested expanded or hatching blastocysts in frozen embryo transfers cycles. Group Leaders arent expected to spend any additional time in the community, and are not held to a set schedule.

VerMilyea. PGS testing was done before initial freeze. Good quality (3BB) and poor quality (<3BB) were evaluated: Awadalla et al. Bromer JG, et al. This doesnt mean that a low quality embryo wont go on to form a pregnancy. Ploidy rate by blastocyst hatching status (fresh and FET cycles considered together). Whats more important, the expansion of the embryo, the ICM, or the trophectoderm?

(2018)looked ateuploidembryos in women <35: So grading appears to give euploids a ranking order for transfer, just like what weve seen with untested embryos. The blastocoel is full at expansion stage 3 and by 3 to 4 the embryo itself is starting to grow larger. Limitations include the retrospective design and data from a single institution. These embryos are assisted hatched, where the embryologist uses a laser to make a tiny hole in the zona.

Notice how the chance of a live birth is predicted to decrease with age (discussed more below), and that day 3 embryos with fewer cells generally dont do as well. Cytoplasmic pitting has a negative influence on implantation outcome. They want to see that each cell has a nucleus and that the cells are of equal size. Embryo grading is where an embryologist evaluates an embryo under a microscope and looks for key features. Embryologist said the embryo looked perfect. During my second round of IVF/ICSI I also got 4 blasts again. a valuable technique to use in the laboratory for PGT-A cases. ): But this doesnt mean that an embryos grade will dictate whether or not the embryo will implant.
