The truth about natural fertility and age: while women under 30 have about a 25% chance of getting pregnant naturally each cycle, that chance drops to 20% for women over 30, according to estimates by the American Society for Reproductive Medicine. By 40, the chance of getting pregnant naturally each month is just 5%.
Infertility is a widespread health concern, affecting approximately 15% of couples in Western countries. While infertility has been extensively studied, only in recent years has research focused on the genetic factors influencing both male and female infertility.
It is estimated that genetic abnormalities, including chromosomal aberrations and single-gene mutations, may be present in around 15% of infertile men and 10% of infertile women.
Advancements in genetic research, particularly alongside the development of in vitro fertilization (IVF) techniques, have allowed scientists to identify several genes related to infertility. However, many genetic causes remain unexplored. Today, genetic testing offers valuable insights into the underlying causes of infertility, helping couples assess their reproductive risks and make informed decisions about assisted reproductive technologies (ART).
RobGenes offers an advanced Fertility Genetic Testing Panel that evaluates multiple genetic markers related to reproductive health, hormonal balance, and risk factors affecting fertility. This panel includes assessments for conditions such as endometriosis, polycystic ovary syndrome (PCOS), recurrent pregnancy loss, male and female infertility, and hormonal deficiencies.
Here are seven key facts about genetic testing for fertility, backed by scientific research and expert insights.

1. Genetic testing can identify inherited conditions that impact fertility
Your genes could be one of the reasons your fertility struggles. Hidden genetic factors, like chromosomal translocations, can cause unexplained infertility and recurrent miscarriages. Testing can uncover these roadblocks early.
Genetic testing helps detect hereditary conditions that could make conception difficult or lead to complications during pregnancy. Conditions such as cystic fibrosis, fragile X syndrome, and chromosomal abnormalities can affect fertility or be passed on to offspring.
For example, chromosomal translocations—where genetic material is rearranged—are a leading cause of recurrent pregnancy loss. Identifying such issues early can help couples explore reproductive options such as in vitro fertilization (IVF) with genetic screening.
2. Carrier screening can assess genetic risks before conception
You might be a carrier of a genetic condition without knowing it. Many people unknowingly carry recessive genetic mutations that could impact their child’s health. Carrier screening reveals risks before conception.
Carrier screening is a type of genetic test that determines if an individual carries recessive genetic mutations that could be inherited by their child. This is particularly important for conditions such as Tay-Sachs disease, sickle cell anemia, and cystic fibrosis.
If both partners are carriers of the same condition, they may have a higher risk of passing the disorder to their child, allowing them to consider options like preimplantation genetic testing (PGT) or using donor gametes.
3. Preimplantation Genetic Testing (PGT) improves IVF success rates
Choosing the healthiest embryo could result in a higher IVF success rate. Preimplantation genetic testing (PGT) helps select embryos with the best genetic profile, increasing implantation success and reducing miscarriage risks.
For couples undergoing IVF, preimplantation genetic testing (PGT) can significantly improve success rates by ensuring only chromosomally healthy embryos are implanted.
PGT screens for conditions like Down syndrome, Turner syndrome, and other aneuploidies, which are among the leading causes of miscarriage and failed implantation.
By selecting embryos with a normal genetic profile, PGT helps reduce the risk of miscarriage and increase the chances of a healthy pregnancy.
4. Age-related genetic risks increase over time
Age doesn’t just affect fertility—it affects genetic risks too. The older you are, the higher the chance of chromosomal abnormalities in eggs and sperm.
As women age, the likelihood of genetic abnormalities in eggs increases, leading to higher rates of miscarriage and conditions like trisomy 21 (Down syndrome). Research shows that the risk of chromosomal abnormalities rises sharply in women over 35.
Genetic testing, including ovarian reserve testing and embryo screening, can help assess reproductive health and guide decision-making for those considering fertility treatments.
5. Genetic testing can help men assess fertility issues
Male fertility does not automatically relate to sperm count, genetics also play a role. Genetic factors like Y chromosome microdeletions or Klinefelter syndrome can lead to infertility in men—testing helps uncover the root cause.
While much of the focus is on female fertility, male genetic factors also play a crucial role. Genetic testing can detect issues such as Y chromosome microdeletions, which affect sperm production, and conditions like Klinefelter syndrome, which impacts testosterone levels and fertility.
Men with unexplained infertility can benefit from genetic testing to determine whether medical intervention or assisted reproductive technologies (ART) are needed, contact RobGenes to explore these options.
6. Genetic counseling is essential for understanding test results
Understanding your genetic test results requires expert guidance, as the journey rarely stops there.
Genetic test results can be complex, requiring expert interpretation. Genetic counseling helps individuals and couples understand their risks, reproductive options, and next steps based on their unique genetic profiles.
Counseling is especially beneficial for those who:
- Have a family history of genetic disorders
- Have experienced multiple miscarriages
- Are planning IVF or using donor eggs/sperm
7. Genetic testing is a proactive step in fertility planning
While genetic testing does not guarantee pregnancy, it provides critical insights into reproductive health that empower individuals to make informed decisions.
With advancements in precision medicine and genetic screening, those trying to conceive can reduce uncertainties, improve IVF outcomes, and lower the risk of genetic disorders. As fertility science continues to evolve, genetic testing will play an even greater role in shaping family planning strategies.
Robgenes’ Fertility Panel offers a comprehensive evaluation of genetic factors affecting reproductive health, including conditions such as polycystic ovary syndrome (PCOS), hormonal imbalances, and recurrent pregnancy loss.
Genetic testing offers an evidence-based, proactive approach to fertility planning, helping individuals and couples understand potential risks, improve treatment success rates, and prepare for parenthood.
If you are considering fertility treatments or want to learn more about your reproductive health, consulting a specialist and exploring genetic screening options may be a beneficial step in your journey.
