Advantages of Blastocyst Transfer
How blastocyst culture helps for high success in IVF treatment?
Blastocyst is an embryo which has developed to day 5 stage with different cell components and a fluid cavity.
The advantage of blastocyst cultures is the selection of best #embryo because only the embryos with high potential for development reach the #blastocyst stage. Pregnancy chances are high when using a blastocyst then with an embryo of day 2 or 3 development. Frozen embryo transfer is more successful with blastocysts as they survive the #freezing and thawing process well. Blastocysts are also used for embryo diagnosis in #PGD. Blastocyst cultures are particularly useful when a good yield of eggs is obtained. With lower number of eggs there is risk of failure of development into blastocyst.
Blastocyst culture can help to determine which embryos have the best chance of being able to implant. Extended culture allows the embryologist to identify which of a group of embryos have the best potential for implantation. If IVF does not work repeatedly with good embryos replaced on day 2 or 3, blastocyst culture can be tried. Extended culture allows the embryologist to identify which of a group of embryos have the best potential for however the chances of having no embryos for transfer at all are also higher. Transferring embryos at the blastocyst stage also provides a better co-ordination between the embryo and the uterus by putting the embryo back in the uterus at the right time.
