Answer from: Dimitra Christopikou, Clinical Laboratory Geneticist
Yes you can, in very busy labs that can apply NGS on a daily basis but I do not know if this is feasible for big labs that apply NGS for chromosome analysis of pre-implantation embryos. However, I would not recommend a first embryo transfer as in our hands at least we have seen, and there are many reports out there, that when you transfer an embryo back on day 6 or day 7 of embryo development in a uterus of a woman that has been stimulated, then the endometrium) might be out of phase and you will have lower pregnancy rates. So you don’t benefit from fresh embryo transfers and most of the time the embryos don’t implant even if they are normal as you will miss the window of implantation. However, I think it is feasible with the latest NGS technique but in very big genetic labs.
Can you do genetic testing for fresh embryo transfer?
We get used information that with genetic testing there is no chance for fresh embryo transfer. Is that always a case? What if we would insist on fresh embryo transfer and we would like to proceed with genetic testing?
