Blastocyst-ET cycle

Blastocyst Transfer

A Blastocyst-ET cycle or blastocyst transfer is an embryo transfer which involves transferring one or more embryos that are at a very advanced stage of development, the so-called blastocyst stage. This is usually done on the fifth day after follicular aspiration.

Blastocyst-ET cycle process

After the doctor has removed the eggs from an ovary (follicular aspiration), they are fertilized in the laboratory. This is done either by normal in vitro fertilization (IVF) or by means of intracytoplasmic sperm injection (ICSI).

stages of development are as follows:

  • the pronuclear stage on the first day (fertilized egg)
  • the two to the four-cell stage on the second day
  • the eight-cell stage on the third day
  • the morula stage on the fourth day and
  • the blastocyst stage on the fifth day

The doctor usually inserts one or more embryos in the woman’s uterus two to three days after egg retrieval. This process is referred to as embryo transfer.

The embryos can also develop in an incubator up to the fifth day, i.e. the blastocyst stage, thanks to improved cell culture media (blastocyst culture). If the doctor transfers such developed embryos into the woman’s uterus, this is referred to as blastocyst transfer.

What are the advantages of blastocyst transfer?

It is possible to identify embryos with development potential

Only 20 to 30 percent of the fertilized eggs develop into blastocysts at all. If an embryo reaches this stage, there is a higher chance of implantation.

The moment of blastocyst transfer is ideal

Just like with a blastocyst transfer, in a natural pregnancy, it takes around five days after fertilization for the embryo to reach the uterine cavity, where it then implants. It is assumed that the lining of the uterus is particularly receptive on this day.


What are the success rates of blastocyst transfer?

The chances of getting pregnant after blastocyst transfer are very high. Compared to embryo transfer at an early development stage (day 2 or 3) the odds are increased by around 7 %. In women up to the age of 30, the chance of success is between 45 and 50 percent, and for women aged 30-39, it is between 35 and 40 percent. However,  blastocyst culture does not provide the same advantages for all women. Those with a low egg count and quality may indeed benefit from a day-3 transfer, in which the embryos are inserted in the mother’s uterus at an earlier stage. It, therefore, goes without saying that our reproductive medicine specialists will work together with you to determine the best transfer method for you as part of a ‘personalised, individual medical approach’, thus striving for the best possible chance of success for you.

Blastocyst-ET cycle (complete cycle)


Embryo transfer is a simple procedure that follows Blastocyst and is often considered the simplest and final step of the Blastocyst process. The objective of embryo transfer is to facilitate conception following fertilization from the Blastocyst procedure.

When Does The Embryo Transfer Procedure Occur?

Embryos are generally transferred to the woman’s uterus at the 2-8 cell stage. Embryos may be transferred anytime between day 1 through day 6 after the retrieval of the egg, although it is usually between days 2-4. Some clinics are now allowing the embryo to reach blastocysts stage before transferring, which occurs around day 5.
