In this video, we explain why it is necessary to screen egg donors to ensure they are genetically compatible with the sperm provider. If you prefer text, we have the video transcribed for you below.
Today, we will be talking about genetic compatibility.
Part of the fertility clinic’s pre-screening is to confirm that you are genetically compatible with the sperm provider.
As the egg donor, you will be required to complete a genetic carrier screening test, such as Invitae. It can be drawn at the clinic via blood test or a kit could be sent to your home and collected via spit. It usually takes about three to four weeks to get your results back.
Once your results come back, it will show if you are a carrier of any genes. Usually, people carry about one to three genes. So, it’s totally normal to be a carrier.
If you and the sperm provider both carry a different gene, there is a 25% chance that the child would be unaffected.
If the child carries either gene, they will be considered a healthy carrier.
If you and a sperm provider both carry the same gene, you are then considered genetically incompatible as there’s a 25% chance that the child will be affected.
