What Is Fertility Planning and How Can It Reduce the Risk of Genetic Conditions in Babies?

Planning for pregnancy is not only about tracking ovulation or taking prenatal vitamins. For some couples, fertility planning can also include checking whether they carry genes linked to inherited conditions. Doing this before conception can help identify possible risks early and give couples time to understand their reproductive options.

“This is particularly important when there is a known genetic condition in the family, a previous pregnancy or child affected by an inherited condition, or when either partner is known to be a carrier of a genetic disorder,” shares Dr Anuradha Vats, Senior Consultant - Obstetrics and Gynaecology at Prayag Hospitals, Noida.

What Is Fertility Planning?

Fertility planning refers to preparing for pregnancy before trying to conceive. It can include reviewing medical and family history, checking existing health conditions, discussing medicines and lifestyle factors, and considering genetic or carrier screening when appropriate.

Preconception care can also include a review of family and genetic history, followed by discussion about carrier or other genetic testing where relevant.

The aim is not to guarantee a baby without a genetic condition. Instead, it helps couples understand potential risks before pregnancy and make informed decisions.

What Are Carrier Tests?

Some people carry a changed gene without having the condition themselves. They may not have any symptoms but can potentially pass the altered gene to their children.

Sickle cell disease and thalassaemia are examples of inherited blood conditions where carrier screening can be important. A person who carries one altered gene may be healthy but can pass it on to their baby.

According to a study published in the journal ‘Genes’, if one partner is found to be a carrier, testing the other partner may help determine whether there is a significant chance of the baby inheriting the condition.

The exact risk depends on the condition and the way it is inherited. This is why genetic counselling can be useful when a carrier result is identified.

Why Should Genetic Testing Happen Before Pregnancy?

Genetic testing before conception gives couples more time to understand the results and discuss their options.

According to a study published in the Cureus Journal of Medical Science, if both partners carry a gene for a condition inherited in a particular pattern, there may be a chance that their baby could be affected. A genetic counsellor or specialist can explain the inheritance pattern and the possible outcomes.

For some conditions, reproductive options may include natural conception followed by prenatal testing, or IVF with preimplantation genetic testing in suitable circumstances. Other options may also be discussed depending on the condition, family circumstances and local medical services.

Having this information before pregnancy can therefore prevent couples from discovering a known genetic risk only after conception.

Who May Benefit From Genetic Counselling?

Not everyone needs extensive genetic testing before trying for a baby. However, speaking to a doctor or genetic counsellor may be particularly useful if there is a history of an inherited condition in either family.

It may also be considered when one partner has a known genetic condition or is already known to be a carrier. Couples with a previous child affected by a genetic condition may also need specialist advice about the chance of it happening again.

A detailed family history can sometimes reveal patterns that may not have been recognised as genetic before.

Can Fertility Planning Prevent Genetic Conditions?

It is important to understand the difference between reducing risk and preventing risk completely.

Genetic screening cannot prevent every genetic or developmental condition. Some conditions are inherited, while others result from changes that cannot be predicted before conception. Screening tests also do not detect every possible condition.

However, identifying a known inherited risk before pregnancy can provide more opportunities for testing, counselling and reproductive planning.

Pregnancy screening can also identify the chance of certain conditions. For example, screening during pregnancy can assess the likelihood of conditions such as Down's syndrome, Edwards' syndrome and Patau's syndrome, while ultrasound scans can look for certain physical differences.

What Should Couples Do Before Trying To Conceive?

A preconception appointment can be a useful starting point. Couples can discuss their personal and family medical history, existing health conditions, medicines, and any concerns about inherited disorders.

If there is a known genetic condition in the family, it is better to mention it before pregnancy rather than waiting until after conception. Genetic counselling can help explain whether testing is appropriate and what different results could mean.

Fertility planning is therefore not simply about improving the chances of conception. For couples with a potential inherited risk, it can also provide valuable information before pregnancy begins.

Final Word

Understanding your family history and discussing possible genetic risks with a healthcare professional before conception can help you make informed reproductive choices. It cannot guarantee a healthy baby, but early planning can provide more time for appropriate testing, counselling and care.
