What is Blastocyst treatment?
The Blastocyst treatment or transfer is done when embryos can be cultured for up to six days, until they become blastocysts. At this stage it is usually easy to select the best quality of the embryo(s). With this technique the embryos are cultured in the laboratory incubator until they reach the blastocyst stage before they are transferred to the womb.
At this stage, one or two of the best quality blastocysts are then selected and implanted into the womb. A blastocyst must successfully attach itself to the wall of the womb, so that a woman can become pregnant.
Who is it for?
The best fertility clinics are now offering this treatment as a means of improving the chances of pregnancy after a single embryo transfer. This procedure is particularly useful for the young women that have a good prognosis for pregnancy from IVF.
An IVF doctor may also suggest to go for blastocyst transfer if they have produced good quality embryos in their previous IVF cycle but they had failed to implant in the womb.
This procedure is not normally recommended if someone produces less than normal healthy eggs.
As with embryo transfer, due to the risks of a multiple birth, someone may want to consider a single blastocyst transfer. Indeed, your fertility centre may encourage to have only one transferred.
