Sex or gender selection is not allowed in every country. Thus, the availability of IVF with PGD for gender selection depends on the location of your fertility clinic. Most patients who wish to select the gender of their baby-to-be travel to the United States to do so, as the majority of laws by state are favorable to its performance.
Embryos can be genetically biopsied with PGD prior to fertilization with IVF. Once one cell of the embryo is removed, its chromosomes can be analyzed to detect potential genetic defects and determine the embryo's gender. Then, only the embryos of the desired gender are selected for the transfer.
