These results demonstrate a 1:1 gender ratio for actively growing day-5 embryos and confirm that the aneuploidy rate is not influenced by the gender of the embryo. The blastocyst stage is not just another day on the calendar; it’s a critical developmental checkpoint. We compared blastocyst development and … Has anyone here had a successful pregnancy using a 5BB embryo? I finished a round of IVF where they only got one egg from me.

The ability of an embryo to use it’s own genes and make it’s own energy is not simple. In addition, this gender bias was consistent whether the blastocyst was biopsied on Day 5 or Day 6. In some cases, as decided by the treating specialist, an embryo transfer may be scheduled for Day 2 or 3. Because embryos are developmentally different on these days, we have different grading systems for day 3 (cleavage stage) embryos and day 5 (blastocyst stage) embryos. We hypothesized that … Day 5 or Day 6 (Blastocyst stage embryos) At the cleavage stage, embryos are graded based on the number of cells, the symmetry of the cells, and the degree of fragmentation (cell … Since your blastocyst was transferred at 12 PM, implantation typically occurs: Between 1–2 days post-transfer for a Day 5 blastocyst (approx. Only blastocysts with the highest probability of implantation are biopsied. On day 5, embryos should be reaching the blastocyst stage of development. What does it mean to transfer a top quality “perfect” embryo then?
