Do all couples need genetic testing before trying to conceive?

Most couples do not require genetic testing because they conceive naturally without any issues. The test becomes a requirement if you are struggling to get pregnant without a clear cause, experiencing losses, or have a history of inherited conditions.

Does being genetically incompatible mean you can never have children?

Genetic incompatibility makes conception difficult, but you can still get pregnant with the help of medical support, such as IVF with genetic screening.

Is genetic testing expensive and complicated?

Genetic testing is a simple procedure that uses a blood sample or cheek swab to detect genetic mutations. Although cost may vary, most fertility clinics offer this test as part of their treatment plans to improve the success rates.

Can Genetic Matching Between Partners Affect Fertility?

Sometimes the fertility struggles go beyond maintaining a healthy lifestyle to support conception. Many couples change their habits to create a positive environment and bring a new life into the world. However, despite taking these measures, some may still experience difficulties in getting pregnant.

If you are in a similar situation, do not ignore genetic compatibility as one of the reasons preventing pregnancy. It is not just your genes, but how they interact with your partner’s genes that can influence your chances of conceiving. They also decide the health of your future child.

What Does Genetic Matching Mean?

Genetic matching involves identifying the differences or similarities in your genes and your partner’s genes. You may be aware that every individual has a unique set of genes that they inherit from their parents, but some of them may carry mutations.

How Genes Influence Fertility

A successful conception not only requires healthy eggs and sperm, but also their genetic compatibility.

Egg and Sperm Quality: Genes determine the health of your reproductive cells. Mutations in genes may lead to poor egg development in females or reduced sperm motility in males.
Embryo Development: Certain genetic mismatches may prevent the embryo from developing properly even after fertilisation, leading to early miscarriage.
Inherited Disorders: The presence of the same faulty gene in both you and your partner will increase the chance of your child inheriting a genetic disorder. This reason does not always prevent pregnancy, but it can influence your decision regarding starting a family.

The Role of Genetic Compatibility in Reproductive Health

Genetic compatibility is more crucial than many people realise, as backed by many scientists. Healthy couples with no medical issues may undergo various problems in conceiving if their genes do not align with each other.

For instance, the HLA (human leukocyte antigen) system is present in some immune system genes that help differentiate foreign factors from their own. The chances of conception are low, or the risk of loss is higher if the HLA is the same in couples.

Your doctor may suggest genetic testing if you are struggling to get pregnant even after multiple attempts without any clear reason for infertility.

When Should You Consider Genetic Matching?

Genetic testing is not a standard routine fertility test, so you may not need it if it has been only months since you started trying. However, it can be helpful under the following circumstances.

You have had multiple miscarriages with no clear cause.
There is a history of genetic disorders in either of your families
You have had more than 2 failed IVF cycles
Case of consanguineous marriages
Case of severe oligospermia (sperm count < 5 x 10^6/mn)

Genetic testing can help identify genetic mutations present in your and your partner’s genes or if the genes of your immune system are affecting fertility.

How Genetic Testing Works

Genetic testing involves taking blood samples or cheek swabs from both partners for DNA analysis and assessing the potential risks associated with the results.

Carrier status for inherited conditions (like thalassemia, cystic fibrosis, or sickle cell anaemia).
Chromosomal abnormalities that may affect embryo development.
Immune system compatibility could influence implantation and pregnancy success.

Your doctor will guide you on the next steps, whether it is to continue trying to conceive naturally or through other fertility treatments, after assessing the results from your test.

What If You and Your Partner Are Genetically Incompatible?

It is natural to feel stressed when you discover a lack of genetic compatibility between you and your partner. However, it does not mean you cannot get pregnant, but it may take some time or medical assistance.

Preimplantation Genetic Testing (PGT): In IVF, the genetic issues in embryos are checked before implanting them in the uterus.
Donor eggs or sperm: If a genetic condition is present in one partner, a donor is an option.
Medical counselling: You can take the help of a genetic counsellor to understand the risks and guide you through your decision-making process.

A healthy pregnancy carries the compatible genes from both partners, but a mismatch in genetic material can lead to problems with conception and embryo development. Your pregnancy may not reach its full term and may result in loss due to genetic problems.
Such cases require genetic testing, and also when you have unexplained infertility, recurrent losses, or a history of inherited conditions. Please do not lose hope if you encounter a similar issue. Modern treatments and genetic counselling can help you find a way through it to help you carry a successful pregnancy.
