Every week couples in America are looking into gender selection. Whether they want to select the sex of the baby because they’ve had all girls or all boys on their own, or just wanting the freedom of choice, preimplantation genetic diagnosis or PGD, is becoming more and more popular among couples.

PGD or pre-implantation genetic diagnosing is achieved by utilizing IVF. The woman’s eggs are taken and injected with sperm to form the embryo. Once the embryo has formed, DNA sampling can determine the sex and then depending on your choice, male or female embryos can be placed back in the uterus.

Pre-implantation genetic diagnosing can be costly, usually running around $20,000. The flip side is that this procedure has almost a 100% success rate.
