Preimplantation Genetic Screening

“Preimplantation Genetic Screening (PGS) is an advanced technique used in conjunction with IVF where embryos can be screened for chromosomal abnormalities. PGS provides genetic information about embryos’ genetic health to help the physician select the best embryo for transfer and improves the chance of achieving a successful pregnancy.”

– Adelle Lim, Chief Embryologist of Alpha Fertility Centre.


It is widely known that maternal age is associated with increased risks of genetic abnormalities and lower success rates during IVF  treatment. As a rule of thumb, an older woman’s eggs are just not as healthy as someone below the age of 35, simply because her eggs are as old as she is and have been exposed to more years of DNA alterations resulting from diet, lifestyle and environmental pollution.

The genetic material housed within chromosomes determines the healthy growth and development of the child. With increasing age of the woman, the potential for chromosomally abnormal embryos significantly increases.

In couples who are having recurrent failed IVF attempts, PGS can detect the chromosomal abnormality that is causing the embryo failed to implant.

With this added genetic information, Specialist will be able to provide solutions that can increase your success in IVF treatment. Other indications for PGS include women with unexplained recurrent miscarriages, women over the age of 35, you had a prior pregnancy with a chromosome abnormality, men with severe male factor infertility or you want to improve your IVF pregnancy success rate.
