Can you please give your opinion on day 3 vs day 5 transfers? I understand there are arguments for both sides. One side: Transferring day 5 (blasts) correlates better with the natural timing of blasts reaching the uterus for implantation. Also, blasts usually represent a stonger embryo with better chances of implantation.
Other side: Transferring day 3 embryos gets the embryos in the uterus sooner (which is a better invironment for the embryos than a petri dish). Better grading and tests (HLG-A) "marker" done by SIRM clinics that suppossedly can predict the embryos that would most likely make it to blast therefore allowing them to choose the best ones on day 3.
What do you think?
