What percentage of embryos pass PGT-A / PGS testing?
How many embryos pass genetic testing?
There are reasons to proceed with genetic testing and they should be discussed individually. One should consider testing not only when there is known gene mutation in the family tree but also when repeated miscarriage is present or the age of mother suggest likelihood of uneploidity.
This is a fluctuating answer and depends on the couple. Every couple has a different type of embryos and development of embryos and also what we see is that in the same couple we have different development of embryos in different stimulation cycles. The percentage of day 3 embryos that make it up to blastocyst in good IVF labs, is around 40%. In some labs it may be more or less, so 40% of day 3 embryos make it up to blastocyst and good-looking, well-developed blastocysts. This is the number you are expecting. You are expecting around 30% of oocytes that are being collected or 40% of embryos that can go for PGTA testing.
