A blastocyst is an embryo that has developed successfully to day 5 of life. Embryos cannot survive long in the labs because, by day six, these blastocysts hatch out of the eggshell and require the mother's uterus to latch on and develop further. A blastocyst transfer is done on day 5 after the oocyte retrieval.

For whom Blastocyst IVF Transfer is suggested?
The best fertility clinics are now offering Blastocyst treatment as a means of improving the chances of pregnancy after a single embryo transfer. This procedure is particularly useful for young women that have a good prognosis for pregnancy from IVF.
Our IVF doctors may also suggest going 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 births, someone may want to consider a single blastocyst transfer. Indeed, we encourage to have only one transferred.
The success rate in cases with blastocyst transfer is as high as in natural conception the embryo enters the uterine cavity at this stage of development and implantation takes place.
Blastocyst transfer in India is done in the cases of previous IVF failures cycles, and in cases of secondary infertility where the couple has only one child but to reduce the chance of multiple pregnancy blastocyst transfers is done.
