Reproductive genetics questions

If you have a question about Reproductive Genetics you might find an answer below. 

When you’re considering or having fertility treatment, you’re bound to have lots of questions. We’ve answered some of our most frequently asked questions below, but if you can’t find the answer you’re looking for, get in touch  – we’ll do what we can to help.

PGS - Pre-implantation Genetic Screening

PGS stands for pre-implantation genetic screening. It’s an innovative technique that we use at CARE to screen embryos’ chromosomes, and it can help us to choose only the very best embryos for transfer. You can find out all about it here.

If you choose to have PGS, you’ll firstly go through an IVF cycle to create embryos. We’ll then take a small number of cells from each embryo for testing. 

An embryo biopsy is when one of our highly skilled embryologists removes a small number of cells from the outer layer of a five or six-day-old embryo. At this stage, the embryo is called a blastocyst, so you might have heard it referred to as a blastocyst biopsy instead.

Biopsies form part of our pre-implantation genetic screening and pre-implantation genetic diagnosis procedures.

You really don’t need to worry about damage to your embryos. Embryo biopsy and micro-manipulation of embryos have been carried out in laboratories across the world, and have been used in genetic cases for more than 25 years. Studies so far have shown these procedures are perfectly safe, and don’t cause any increased risk to children born as a result.

We hope this sets your mind at rest, but if you’re still unsure or have further questions, speak to your local clinic or contact us.

PGD - Pre-implantation Genetic Diagnosis

Pre-implantation genetic diagnosis (PGD) is a technique that allows genetic testing of an embryo before it’s transferred. If your family is affected by an inherited disease, we can use PGD during IVF treatment to choose embryos without this condition for transfer, reducing the risk of passing on to your children.

You can find out more about PGD here.

After you’ve had a cycle of IVF treatment we’ll take cells from the embryos and test them for the specific genetic illness or condition. If we’re able to identify embryos without the condition, these can be transferred.
