Gender Selection

Current Options to Select the Sex of Your Baby

Currently, the only technique to select a desired gender is pre-implantation genetic diagnosis (PGD). This technique is achieved by performing IVF and growing embryos in the laboratory for three days to the eight-cell stage. At this point, a small opening made in the zona pellucida and one of the cells of the embryo is gently removed. The cell that is removed is fixed to a slide and sent for genetic analysis to a central laboratory. It is then that gender determination, chromosome X or Y, as well as other chromosomal abnormalities can be evaluated. By transferring only embryos of the desired gender, a better than 95% probability of successful gender selection can be achieved.
