Does Embryo genetic analysis decrease the rate of spontaneous miscarriage?
Yes. ‘Embryo Genetic Analysis’ can significantly reduce spontaneous miscarriage because most of them are due to genetic anomalies. Does ‘Embryo Genetic Analysis’ prevent the birth of children with chromosomal abnormalities? Yes. It can avoid the birth of children with chromosomal abnormalities such as trisomy 21 or Down’s syndrome. How is embryo genetic análisis performed? In vitro fertilization-derived embryos are cultured until Day 3 of development at which stage embryos have 6 to 8 cells or blastomeres. Then, a hole is made in the zona pellucida (the layer that covers the embryo) and one cell is aspirated using a special micropipette (biopsy procedure). The aspirated cell is processed for genetic analysis while the embryo is mantained in culture. Genetically normal embryos are transferred to the uterus the next day. Could this technique damage the embryo? The biopsy procedure is highly sophisticated technique that when performed by experienced embryologists should not negatively aff
