Blastocyst Culturing (Growing)
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.
Our clinic is now offering blastocyst transfer as a means of improving chances of pregnancy after single embryo transfer. This is particularly useful for younger women with a good prognosis for pregnancy from in vitro fertilisation (IVF).
Your doctor may also suggest you try blastocyst transfer if you have produced good quality embryos in a previous IVF cycle but they failed to implant in the womb.
