The advantage of day 5 embryo transfer is that there is a high chance of successful implantation compared to letting the embryo develop naturally in the mother's uterus.
Embryogenesis stages:
Prokaryotic stage (day 0 - Day 1) mitotic stage (day 1 - day 3) Early morula stage (day 3 - day 4) blastocyst stage (day 5) +) High success rate of embryo transfer on day 5 is not a question of many couples, the reason why many medical facilities choose day 5 embryo transfer is because: High success rate of embryo transfer, reducing the risk of multiple pregnancy, safer for genetic testing, safer to freeze embryos and thaw embryos.
On the other hand, day 5 embryo culture is an advanced technique, which gives a high chance of pregnancy after embryo transfer (success rate of day 5 embryo transfer is up to 70%), thanks to the careful selection The more the mother will have less miscarriage, each day 5 embryo transfer, the doctor will only transfer 1-2 embryos, so it helps to limit the possibility of multiple pregnancies, the preimplantation genetic screening helps to eliminate the risk of the fetus. have birth defects.
