Pre-Implantation Genetic Diagnosis (PGD Testing) in NYC
Development of micro-manipulation skills and techniques in the IVF laboratory led to the possibility of biopsy – in which a cell is detached from a viable embryo (usually at the 8-cell stage) so its chromosomes and a growing number of gene mutations responsible for hereditary diseases can be analyzed. This analysis is called pre-implantation genetic diagnosis (PGD) and can help ensure that the baby is healthy and allow the parents to choose their baby’s gender.

What is pre-implantation genetic diagnosis used for?
Pre-implantation genetic diagnosis (PGD), also known as pre-implantation genetic screening (PGS), has become commonly used in the past 15 years to screen embryos for:
- Chromosome abnormalities
- Presence of gene mutations linked with specific diseases
- Gender selection in order that only chromosomally normal embryos which do not contain a specific disease screened for, and/or which are male or female are selected for embryo transfer
Since a number of serious diseases are linked to the female X chromosome, PGD can determine the sex of each viable embryo by identifying the sex chromosomes present in each embryo (XY chromosomes if male, XX if female). Identifying the sex of each embryo by PGD has also enabled a foolproof means of selecting for transfer only those embryos that have the gender desired by the couple for their child.
An added fee is charged for PGD to cover the cost of the genetic analysis done by a licensed genetics laboratory.
Of course, the first condition for a successful PGD outcome is that the patient must get pregnant. If IVF/PGD is performed on a normal, healthy woman younger than 37, who has no infertility problems, her chances of pregnancy are 60% or more. Chances are lower for women with infertility problems and for women older than 37.
