PGD is a very sophisticated technique that is used with IVF
. During a regular IVF procedure when the embryo is three days old, some cells are removed or added using a tiny surgical needle. The next step involves evaluating the genetic makeup of the embryos using techniques such as gene amplification and chromosome analysis. Later, the desired embryos are transferred to the uterus of the female for carrying out the regular course of pregnancy. And, the expected parents can look forward to their bundle of joys. Having the power of determining your baby's gender in advance is truly a boon, thanks to the medical advancements.
