What is a blastocyst?
A blastocyst is an embryo that has developed for five to six days after fertilisation.
With blastocyst transfer, embryos are cultured in the laboratory incubator to the blastocyst stage before they are transferred to the womb.
At this time, one or two of the best quality blastocysts are selected and then implanted into the woman’s womb. A blastocyst must successfully attach itself to the wall of the womb for a woman to become pregnant.
The additional day’s culture in the laboratory enables the natural selection process to continue and so we can select the best embryos to transfer.
Is blastocyst transfer for me?
Your doctor will discuss with you whether blastocyst transfer is appropriate in your situation.
