Is Blastocyst Transfer beneficial?
A blastocyst is an embryo that has developed in culture for at least five days after fertilization and then is transferred in the female womb. This is a more physiological approach since it is known that under in-vivo conditions the embryos reach the uterine cavity around the end of the sixth day following fertilization. This also allows at times for natural selection of best quality embryo as only the better quality, genetically normal embryo will grow to this stage. Q11: What is Pre-implantation Genetic Diagnosis (PGD)? Preimplantation genetic diagnosis (PGD) allows the embryologist and physician to screen embryos for certain inherited genetic diseases. Each cell in the body, and in an embryo, contains the full genetic blueprint of a person and hence the chromosomes from any cell can be examined for abnormalities. After PGD, embryos that are not carrying the genetic disorder are selected for transfer. Embryonic cell from 8-cell embryo is biopsied Q12: What is a donor programme and wh
