What is Genetic Compatibility?

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. 

Enhancing Egg Donation Success: The Role of Genetic Screening by Donor Nexus

Today, we will be talking about genetic compatibility. 

Part of the egg donation process and 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.

Genetic Compatibility for Egg Donors: FAQs

Why do egg donors need genetic screening?
Genetic screening helps confirm compatibility between the egg donor and sperm provider, reducing the risk of passing on certain inherited genetic conditions.

Is it normal for an egg donor to be a genetic carrier?
Yes. Most people carry one to three genetic traits, and being a carrier is common and does not affect overall health or fertility.

What happens if the egg donor and sperm provider carry different genes?
If they carry different genes, the child is not at increased risk and may simply be a healthy carrier.

What if the egg donor and sperm provider carry the same gene?
When both carry the same gene, there is a higher chance the child could be affected, and the donor and sperm provider are considered genetically incompatible.

How long does genetic screening take for egg donors?
Results typically take about three to four weeks after the sample is collected.

How is genetic testing done for egg donors?
Testing is usually completed through a blood draw at a clinic or an at-home saliva collection kit.

Does genetic incompatibility mean the donor can’t donate eggs?
No. A donor may be incompatible with one sperm provider but fully compatible with others.
