Blastocyst transfer is a process when the embryos are cultured to the blastocyst stage in the laboratory’s incubator before they are implemented into the womb. Embryos are cultured up to 6 days and then they become blastocysts and it is easier to choose the best quality embryos.
When the best embryos are chosen they are then implanted into the woman’s womb where they have to successfully attach so that the woman can become pregnant. So it is a process very similar to the standard embryo transfer but it is implanted after it is allowed to develop for 5 up to 6 days.
When is blastocyst transfer recommended?
The blastocyst transfer is often recommended for single embryo transfers because statistics show that in such case it improves the chance for pregnancy. It is a very effective technique for younger women which have good prognosis for an IVF pregnancy. Furthermore it is often recommended if a woman had an IVF treatment in the past and she produced quality eggs but they were not able to implant properly in the womb.
Like using embryo transfer also the blastocyst transfer has a risk of a multiple birth and you your clinic will probably suggest you do a single blastocyst transfer.
