PGD can be used to detect which embryos are XX or XY. It allows analysis of the genetic make-up of the early embryo before it is transferred into the uterus. Then, the desired embryos can be placed into the female's uterus to achieve pregnancy.

PGD is performed as part of an in vitro fertilization - IVF cycle. In order for PGD to be performed, couples must undergo IVF to allow for the formation of early embryos in the laboratory. When embryos are three days old (typically containing 7-8 cells), PGD is performed by inserting a tiny needle into each embryo and removing 1 or 2 cells (called blastomeres). Various techniques of gene amplification and chromosomal analysis are next applied in order to analyze removed blastomeres for their genetic make-up. Embryos determined to be abnormal, or of the wrong gender are discarded. Normal embryos are transferred into the uterus within 24 hours of the procedure.

Occasionally, the use of PGD for gender selection may not work because there may not be any embryos of the desired gender produced. IVF with PGD is the most successful and accurate way to perform gender selection. Its only limitation is the fertility potential of the couple attempting pregnancy. PGD is 99.9 percent successful.

Numerous studies have documented the safety of PGD and its benefits in assuring that a healthy embryo is chosen for transfer. Overall, PGD is ideal for couples who have several children of one gender and are interested in sex selection/family balancing. Contact us for a free email consultation!
