What Is Reproductive Genetics?
Reproductive genetics explores how genetic and chromosomal factors may influence fertility, embryo development, pregnancy and the chance of passing an inherited condition to a child. It can help individuals and couples understand relevant genetic risks and consider appropriate testing or counselling when planning a family.
Depending on your circumstances, reproductive genetic assessment may involve reviewing personal and family medical history, investigating a known inherited condition, or discussing genetic testing options before or during pregnancy. The most appropriate approach depends on the clinical question, reproductive history and information already available.
Reproductive genetics can be relevant at different stages of family planning, from investigating possible genetic factors associated with fertility difficulties to considering embryo testing during IVF or prenatal testing during pregnancy. However, not every fertility or pregnancy concern has a genetic cause, and testing is not necessary for everyone.
At London Genetics, the aim is to help you understand the options relevant to your situation, including what genetic tests may identify, their limitations and how the findings could inform discussions with your wider healthcare team.
Who Can Benefit from Reproductive Genetics Assessment?
Reproductive genetics assessment may be helpful for individuals and couples who want to understand how genetic or chromosomal factors could influence fertility, pregnancy or family planning. The most appropriate assessment depends on your reproductive history, personal and family medical history, and any known genetic findings.
You may wish to consider a reproductive genetics consultation if you:
- Are planning a pregnancy and want to understand the possibility of passing on an inherited genetic condition.
- Are undergoing IVF and would like to explore whether genetic testing of embryos may be relevant.
- Have experienced recurrent pregnancy loss and want to discuss whether genetic factors could be involved.
- Are considering using an egg or sperm donor and want to understand relevant genetic screening options.
- Are planning a pregnancy or are pregnant at an older maternal age and would like to discuss age-related chromosomal risks.
- Have a personal or family history of a known genetic condition or chromosome rearrangement that may affect reproductive decisions.
A reproductive genetics assessment does not automatically mean that genetic testing is required. It can help clarify which options, if any, are appropriate for your circumstances and support informed decisions in collaboration with your healthcare team. If testing during pregnancy is relevant, you can also explore prenatal genetic testing.

How Can Genetics Influence Fertility and Pregnancy?
Genetic and chromosomal factors can influence different stages of reproduction, from fertility and embryo development to pregnancy and the possibility of passing on an inherited condition. Their relevance varies between individuals and couples, and not all fertility difficulties or pregnancy complications have a genetic cause.
| Area | Possible Genetic Influence | When Assessment May Be Relevant |
|---|---|---|
| Fertility | Certain genetic variants or chromosomal differences may contribute to fertility difficulties in some individuals. | When there is unexplained infertility, a relevant medical history or a clinical indication for genetic investigation. |
| Embryo Development | Chromosomal abnormalities can affect embryo development and may be associated with implantation failure or pregnancy loss. | During fertility assessment or IVF discussions, depending on reproductive history and individual circumstances. |
| Inherited Conditions | Parents may carry genetic variants associated with an inherited condition, sometimes without having symptoms themselves. | When a known genetic condition or relevant family history may affect reproductive choices. |
| Pregnancy Loss | Chromosomal abnormalities can account for some pregnancy losses, although many other factors may also be involved. | Following recurrent pregnancy loss or when clinical findings suggest that genetic factors should be investigated. |
| Chromosomal Risks During Pregnancy | The chance of certain chromosomal conditions, including trisomy 21, increases with maternal age. | When discussing prenatal screening, diagnostic testing and individual pregnancy-related risks. |
| Donor Conception | Genetic variants carried by a donor may be relevant to the possibility of a child inheriting certain conditions. | When considering donor eggs or sperm and reviewing appropriate screening options. |
Genetic factors are only one part of reproductive health. A personalised assessment can help clarify whether genetic investigation may be appropriate and which options are relevant to your circumstances. Genetic testing cannot identify every possible cause of infertility or guarantee a particular pregnancy outcome.
How Does a Reproductive Genetics Consultation Work?
A reproductive genetics consultation begins with your reproductive goals, medical history and any known genetic concerns. The process helps identify relevant questions, explain appropriate assessment options and support informed decisions about family planning.
Discuss Your Reproductive Goals
Share your plans for pregnancy, fertility treatment or family planning, along with any questions or concerns you would like to address.
Review Medical and Family History
Your personal and family medical history, previous pregnancies, fertility treatment and any existing genetic results may be reviewed where relevant.
Assess Relevant Genetic Factors
The discussion considers whether inherited conditions, chromosome differences or other relevant genetic factors warrant further investigation.
Explore Testing and Counselling Options
If appropriate, available options are explained, including their purpose, limitations, potential implications and whether additional specialist input may be needed.
Discuss Findings and Next Steps
Relevant findings and possible next steps are discussed with you. Depending on your circumstances, this may involve further testing, referral to another specialist or continued care with your healthcare team.
Your consultation is tailored to your individual circumstances. Genetic testing is not automatically required. The aim is to help you understand relevant risks and available options so that you can make informed decisions about your reproductive care.
What Can Reproductive Genetic Testing Tell You?
Reproductive genetic testing can provide information about selected genetic variants or chromosomal differences that may be relevant to fertility, pregnancy or the possibility of passing an inherited condition to a child. What a test can reveal depends on the type of analysis, the specific genetic question being investigated and the information available.
Depending on your circumstances, testing may help to:
- Identify selected inherited genetic variants:
determine whether a person carries a particular variant associated with an inherited condition and, where relevant, help assess the potential risk to a child. - Assess certain chromosomal findings:
identify selected chromosome number abnormalities or structural rearrangements, depending on the test and sample analysed. - Inform reproductive planning:
provide genetic information that may help individuals and couples consider available family-planning or fertility-treatment options. - Support decisions about embryo testing:
where appropriate, help determine whether testing for a specific inherited condition or chromosomal finding during IVF may be an option. - Clarify some pregnancy-related risks:
contribute to the assessment of selected genetic or chromosomal conditions through appropriate prenatal screening or diagnostic testing.
Understanding the limitations is equally important.
No single reproductive genetic test detects every genetic condition or explains every cause of infertility, implantation failure or pregnancy loss. Some results may be uncertain, and screening results do not always provide a definitive diagnosis. The meaning of a result depends on the test performed, the clinical context and, where appropriate, additional investigations.
A reproductive genetics consultation can help you understand what a particular test can and cannot establish, whether further assessment may be useful, and how the findings could inform discussions with your healthcare team. You can also explore our genetic testing services to learn more about the available testing approaches.

How Can Genetic Counselling Support Family Planning Decisions?
Genetic counselling can help individuals and couples understand how genetic factors may affect their reproductive choices. By reviewing relevant medical and family history, explaining genetic risks and discussing available options, counselling can provide a clearer basis for decisions about pregnancy, fertility treatment and family planning.
Depending on your circumstances, genetic counselling may help you to:
- Understand inherited conditions:
explore how a known genetic condition or variant in the family could affect the possibility of passing it on to a child. - Evaluate whether genetic testing may be appropriate:
discuss the purpose, potential benefits and limitations of relevant tests before deciding whether to proceed. - Explore reproductive options:
understand the genetic considerations associated with natural conception, IVF, embryo testing, donor conception or other relevant options. - Interpret genetic results:
understand what a result may mean for reproductive risks and why some findings require further assessment or specialist input. - Consider pregnancy-related decisions:
discuss the differences between prenatal screening and diagnostic testing, including what each approach can and cannot establish. Where relevant, prenatal genetic counselling can help individuals understand these considerations during pregnancy. - Make informed, personal decisions:
weigh the available information in light of your circumstances, preferences and values, without pressure to choose a particular option.
Genetic counselling does not determine which reproductive choice is right for you, nor does it guarantee a particular pregnancy outcome. Its purpose is to help you understand the relevant information, uncertainties and available options so that you can make decisions that suit your circumstances.
Your Reproductive Genetics Journey: Four Steps to Informed Decisions
Reproductive genetics is not a one-size-fits-all process. The aim is to understand your circumstances, identify relevant genetic questions and explore appropriate options for fertility and family planning.
Discuss your reproductive goals, medical history, family history and any known genetic findings to identify the questions that matter to you.
Consider whether genetic counselling, further clinical assessment or a specific genetic test may be appropriate. Understand the potential benefits and limitations before deciding how to proceed.
If testing is appropriate and you choose to proceed, the results are reviewed in the context of the test performed, your clinical history and any relevant uncertainties.
Use the available information to discuss relevant reproductive options and any further assessment with your fertility or healthcare team.
The aim: To help you understand relevant genetic information, available options and their limitations. Genetic assessment cannot guarantee a particular pregnancy outcome, but it may support informed decisions about family planning.
Frequently Asked Questions About Reproductive Genetics
What is reproductive genetics?
Reproductive genetics explores how genetic and chromosomal factors may influence fertility, pregnancy and the possibility of passing an inherited condition to a child. It can help individuals and couples understand relevant risks and consider appropriate assessment or testing options when planning a family.
Who should consider reproductive genetics assessment?
It may be helpful for people planning a pregnancy, undergoing IVF, experiencing recurrent pregnancy loss, considering donor conception or concerned about a known genetic condition in their family. Whether an assessment is appropriate depends on individual circumstances.
Can genetic factors cause infertility?
Certain genetic variants and chromosomal differences can contribute to fertility difficulties in some individuals. However, infertility has many possible causes, and genetic testing is not necessary for everyone experiencing difficulties conceiving.
Can reproductive genetic testing identify inherited conditions in a future child?
Some tests can identify genetic variants associated with specific inherited conditions or help assess the possibility of passing a condition to a child. The information available depends on the condition being investigated, the test performed and the genetic findings detected.
Is reproductive genetic testing necessary before IVF?
No. Reproductive genetic testing is not routinely necessary for everyone undergoing IVF. Depending on medical and family history, a known genetic condition or other clinical findings, a fertility specialist or genetics professional may discuss whether particular tests could be useful.
What is the difference between PGT and prenatal genetic testing?
Preimplantation Genetic Testing (PGT) examines selected genetic or chromosomal findings in embryos during IVF, before an embryo is considered for transfer. Prenatal genetic testing takes place during pregnancy and may involve screening or diagnostic approaches. The purpose, timing and limitations of these tests differ.
Can genetic counselling help before planning a pregnancy?
Yes. Genetic counselling can help individuals and couples understand relevant family history, inherited risks, testing options and the possible implications of results. It supports informed decision-making without requiring a person to proceed with genetic testing.
Does advanced maternal age increase genetic risks during pregnancy?
The chance of certain chromosomal conditions, including trisomy 21, increases with maternal age. Individual risk and available screening or diagnostic options can be discussed with an appropriate healthcare professional.
Can reproductive genetics explain recurrent pregnancy loss?
Genetic or chromosomal abnormalities can account for some pregnancy losses, but they are not the only possible cause. Assessment may be considered based on pregnancy history, clinical findings and whether further investigation is appropriate.
Does a normal genetic test result guarantee a healthy pregnancy or baby?
No. A normal result for the findings assessed does not exclude every genetic condition, chromosomal abnormality or other health concern. The meaning of a result depends on the test’s scope, accuracy and clinical context.
How do I know which reproductive genetic test is right for me?
The appropriate test depends on the clinical question, reproductive history, family history and any known genetic findings. A reproductive genetics consultation can help clarify which options may be relevant and explain their potential benefits and limitations.
