Blastocyst advancement today
Laboratory advancements have delivered knowledge and improved success rates for pregnancy.
We now culture embryo's for five to 6 days to develop a blastocysts containing 80-100 cells, allowing the opportunity to prove their development potential, free of damage.
Some fertilised eggs will arrest ( stop developing) prior to day 5. This natural selection enables the embryologist to more accurately choose the best embryo for transfer and the most likely chance of pregnancy.
Grading the embryos
1. Blastocyst grading
Scoring of blastocysts is an imperfect science, and some very nice-looking blastocysts do not necessarily produce a pregnancy. However, the basic rule of thumb is that the best embryos make it to the blastocyst stage, and therefore has a greater chance statistically of producing an ongoing pregnancy than a lesser quality one.
2. transfer and implantation
Technology advancements like Chloe apply decades of data and algorithms to support Embryologists in selecting and grading blastocysts suitable for implantation. We have invested in this technology in our pursuit for success for our patients.
