Preimplantation Genetic Screening in New York
Preimplantation genetic screening (PGS) tests for chromosomal anomalies in the preimplantation embryos. Human cells have 46 chromosomes (23 were donated by the egg and 23 by the sperm). If there is an extra copy or a missing copy, this will severely inhibit the embryos ability to develop to a healthy term baby and can be a cause for miscarriage. There are many other types of chromosomal anomalies, most of which PGS can screen for. Certain patients are at an increased risk for these anomalies, for example women over the age of 36 or women who have experienced multiple miscarriages. This type of testing is standard across the board and can be set up rather quickly with very little advanced planning.
In some cases a patient may be at serious risk of conceiving a baby which is affected by both a chromosomal anomaly as well as a specific genetic disease. In these cases it is usually possible to test for both problems at the same time.
Preimplantation Genetic Testing Study
RSofNY is conducting a research study with Stony Brook University and The New School. This is a voluntary study for women and men who are thinking about, have chosen to do, or have chosen not to do preimplantation genetic testing within the past 6 months. The study is anonymous and online. The purpose of this study is to investigate considerations, concerns, and factors underlying the decision-making process about whether to use PGT testing.
