Blastocyst Culture Transfer

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 has a better chance to successfully attach itself to the wall of the womb for a woman to become pregnant.
