Embryologist Christine Briton-Jones uses a microscope and micromanipulators to perform a biopsy on the 8-cell stage embryo in order to single out one embryonic cell that will be analyzed for sex determination. The embryos are cultured for 3 days post insemination and at this time healthy embryos will have grown to the 8 cell stage. The Fertility Institutes uses Preimplantation Genetic Diagnosis (PGD) technology in conjunction with in-vitro fertilization to help couples to choose the sex of their future baby with a 99% success rate.
