A blastocyst is an embryo that has been left to develop until day 5 or 6. It has a more complex cellular structure formed by approximately 200 cells. The blastocyst phase is the prior development stage to implantation of the embryo in the mother’s uterus.

Why Blastocyst transfer?

The transfer of blastocysts allowed one or two blastocysts to be transferred with high implantation potential. It also minimizes the risks of multiple pregnancies. Single blastocyst transfer completely avoids twin pregnancy. The advantage to grow embryos to the blastocyst stage is that they should have a more chance of implantation because the phase of embryo development matches the uterine environment.

Blastocyst transfer procedure

This is usually done on the fifth day after follicular aspiration in the lab. After the doctor has removed the eggs from an ovary, they are fertilized in the laboratory. This is done either by normal in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Immediately after fertilization, an egg starts to divide and develop into an embryo.

Success rate

The chances of getting pregnant after blastocyst transfer are very high. In women up to the age of 30, the chance of success is between 45 – 50%, and for women aged 30-39, it is between 35-40 %.
