Can embryo screening reduce the likelihood of a miscarriage?

Posted on 1.2.17

Perhaps you have had recurrent miscarriages in the past or are an older woman concerned about the declining quality of your eggs. Whatever your conception concern, you might find that embryo screening could help you conceive.

Embryo screening is a vital tool many clinics now use to help minimise the risk of miscarriage or still births. Technically referred to as Pre-implantation genetic screening (or PGS) the test typically involves fertilising an egg outside the body and monitoring its cell division growth until it reaches about 100 cells. At this stage one or two cells are removed which are then examined for abnormalities in the number of chromosomes also known as ‘aneuploidy’. If the extracted cells are free of imbalances the healthy embryo can be implanted in the uterus with a reduced likelihood of a miscarriage.

How PGS works

PGS stems from another technique known as Pre-implantation genetic diagnosis (PGD) which is used to help diagnose and avoid known inheritable genetic conditions. The key difference is that PGS focuses on the chromosomal imbalances that prevent the embryo from successfully taking hold in the uterus. PGS would be used when the genetic parents are presumed to be free of any serious genetic conditions but are, for whatever reasons, unable to successfully conceive. By analysing the embryos prior to implantation with the latest time-lapse imaging technology doctors are able to give frustrated women who have endured multiple miscarriages the answers and solutions they need. The Bridge Centre offers women concerned about multiple IVF failures or who have had recurrent miscarriages, advanced screening of embryos using PGS as well as a technology known as Time-lapse photography.  Time lapse technology monitors the development of embryos before they are transferred during an IVF cycle.  This technology combined with PGS can help identify which embryos have a low or high chance of having an abnormal number of chromosomes.  Transferring only embryos with healthy and genetically balanced chromosomes can reduce the incidence of miscarriage resulting in a healthy live birth.

One by One IVF Programme

PGS is a key component of The Bridge Centre’s One by One IVF programme which aims to maximise the chances of a successful and safe single pregnancy. It is central to our clinic’s approach to fertility medicine to use the latest pioneering technologies to spare women the pain of miscarriage.

In addition, women who have suffered from recurrent miscarriages or have had previous failed IVF attempts will receive a unique expert report through our One by One IVF Programme.  This report provides clear information about their chances of achieving pregnancy as well as data from the time-lapse analysis and genetic screening.
