What is PGS?
PGS is a technique used to assess embryos for chromosomal abnormalities. It involves the removal of one or more cells from embryos before they are transferred.
This is followed by testing of the cells to find out the number of chromosomes, using a method called array-CGH. If the cells are found to have an abnormal chromosome number, then the embryo is less likely to implant. In this way embryos can be screened in order to select the most viable embryos for embryo transfer.

Who is PGS suitable for?
PGS can be used by any person/couple undergoing an IVF cycle, but is most suitable for older women who are more likely to have eggs with the wrong number of chromosomes. Abnormal chromosomes are thought to be the main reason why older women have difficulties conceiving and are more likely to have a miscarriage or a baby with Down’s Syndrome.
You may also recommend PGS if:
- you have a family history of chromosome problems
- your sperm is at risk of carrying abnormal chromosomes
- if you’ve had several miscarriages or failed IVF attempts without explanation
Advantages of PGS
How safe is PGS for embryos?
Performing PGS on embryos at blastocyst stage has little or no effect on the successful development of the embryo. This is because an embryo developed to this stage has many more cells, which can be extracted without affecting an embryo’s potential for pregnancy.
The cells which are extracted during PGS are called trophectoderm cells, which will go on to form the placenta.
