Question

Quizplus · Accepted Answer

Transferring embryos at the blastocyst stage (around day 5 after fertilization) has resulted in increased success rates for preimplantation genetic diagnosis (PGD) because it allows for the selection of embryos that have demonstrated continued development and growth, indicating they are more likely to implant successfully.
