Infertility is an issue that affects up to 48 million couples and 186 million individuals worldwide, but until relatively recently, it was considered an insurmountable obstacle to biological parenthood. Defined by the World Health Organization (WHO), infertility is the inability to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse, infertility can still be a confronting diagnosis to receive, but there is now an unprecedented variety of treatment options.
Now considered a rapidly advancing field of modern medicine, fertility treatments are evolving to meet the needs of countless individuals and couples, and a series of groundbreaking innovations have taken place in the last century.
Evolution of fertility treatments
While ancient remedies existed, infertility wasn’t considered a medical issue until as late as the 18th century, beginning with the first documented application of artificial insemination in humans was performed in the 1770s. For nearly 200 years, treatments remained mostly focused on the mechanics of sperm delivery. It wasn’t until 1943 that the first published report of human artificial insemination While the introduction of estrogen and progesterone therapies in the 1940s was revolutionary, these early treatments followed a generalized approach, applying broad hormonal supplements to patients without the nuanced understanding of individual health needs that we have today.
In the 1950s, scientists began successfully fertilizing eggs and achieving live births in animals, through in vitro fertilization (IVF), proving that embryos fertilized outside the body could be successfully transferred and carried to term. Inspiring global interest and research in assisted reproductive technologies (ART), the birth of the first IVF baby influenced the 1980s boom in IVF procedures, and continued improvements in techniques and equipment. This era proved that conception could happen outside the body, yet the protocols remained largely uniform.
The 1990s signaled a definitive move away from generalized care toward targeted intervention. The introduction of intracytoplasmic sperm injection (ICSI) in 1992 allowed doctors to bypass specific male-factor infertility issues that standard IVF could not solve, while the advent of preimplantation genetic testing (PGT) enabled the screening of embryos for individual chromosomal health. This transition transformed fertility care into a proactive, data-driven discipline. Today, this progression continues as treatments shift to accommodate diverse family structures through personalized donor and gestational paths.
This evolution of fertility treatments is a clear example of the rise of personalized (or precision) medicine in healthcare. Significantly shifting away from the historic "one-size-fits-all" approach, personalized medicine was developed to deliver individualized treatment and prevention strategies tailored to each patient’s unique needs.
The principles of personalized medicine, which include using a person's genetic, environmental, and lifestyle data to tailor care, are being applied across many different medical fields to improve treatment effectiveness and reduce side effects. For example:
- In oncology, cancer experts can analyze genetic mutations in tumors to determine targeted therapies or immunotherapies that are more likely to be effective. This type of customized approach helps reduce the need for treatments like chemotherapy which can be far more physically taxing on the patient and less accurate.
- In psychiatry, experts are applying pharmacogenomics, which uses genetic testing to predict how a patient will respond to certain medications.
- In the realm of heart disease, personalized cardiology uses a patient's genetic information to guide both preventative care and treatment.
- In the treatment of rare diseases like cystic fibrosis, which are often caused by a single gene mutation, personalized medicine can help develop targeted therapies that address the root cause of the condition.
Importance of personalization in fertility care
Personalized medicine is essential in the scope of fertility care because it treats each unique person as an individual with specific needs. Not only does this humanize and personalize the often-daunting practice of fertility medicine, but it can significantly improve outcomes, reduce stress, and save money. Because the causes of infertility are complex and varied and result from a combination of genetic, hormonal, and environmental factors, traditional, standardized protocols often fail to account for unique differences.
This failure of generalized methods can lead to repeated failed cycles, emotional distress, and financial burden. Through the continued advancement of modern diagnostic methods, data-driven protocols, and holistic approaches that take lifestyle factors into consideration, personalized medicine allows for more successful, less risky, and more cost-effective treatments that empower patients to make more informed decisions for their future.
What is personalized medicine?
Personalized medicine (also known as precision medicine) customizes healthcare based on an individual’s unique genetics, biology, lifestyle, and environment. Rather than implementing a “universal” model of care, personalized medicine takes into account a person's unique genetic makeup, environment, and lifestyle to guide prevention, diagnosis, and treatment of diseases. While traditional medicine has relied on treatments that work for the “average” patient, personalized medicine recognizes and accounts for the myriad individual differences in each person’s health, allowing for more precise and effective care. These individual differences include:
- Genetics and biology: Moving past general symptoms to treat a patient's specific molecular makeup. For example, studying how a person’s genes affect their response to medications can help personalize drug selection and dosing.
- Environment: Accounting for external stressors and exposures that trigger biological responses. For example, assessing a patient's long-term exposure to air pollution, which may necessitate a different treatment plan.
- Lifestyle: Integrating daily habits and behaviors into the clinical picture. For example, adjusting a treatment plan based on a patient’s sleep patterns or specific nutritional habits to make certain medications more effective.
How personalized care works in general medicine
Within the framework of general medicine, the personalized approach considers genetic testing, biomarkers, and advanced diagnostics to be the foundational tools used to move away from the standardized approach to healthcare. By using these tools, healthcare providers can access a detailed profile of a patient's unique biological makeup, as well as molecular-level insight into their disease to create customized treatments that are tailored for maximum precision and efficacy with minimal side effects.
Genetic testing for a baseline
By analyzing a person’s DNA to identify specific variations, mutations, or inherited traits that influence their health, genetic testing can be used in pharmacogenomics (also known as pharmacogenetics) to study how an individual's genes affect their response to certain medications.
A specific type of genetic testing called germline testing is highly recommended for those diagnosed with certain cancers, and somatic testing (sometimes called tumor testing or biomarker testing) analyzes the genetic makeup of tumors. By confirming the specific type of cancer someone has, doctors can prescribe targeted therapies that are much more precise and effective than other forms of treatment.
Layering in biomarkers
Biomarkers are another important foundational tool in precision medicine. These measurable biological indicators—including proteins, genes, hormones, and other molecules—can help provide insights into a person’s health.
Also known as “molecular markers” and “signature molecules,” biomarkers are biological molecules found in blood and other body fluids, as well as tissues that are signs of a normal or abnormal process, condition, or disease, and can also indicate how well the body responds to a specific treatment.
Adding in advanced diagnostics
Advanced diagnostics are another facet of personalized medicine that include a range of technologies designed to provide a comprehensive view of a patient's health. One type of advanced diagnostics is known as Next-Generation Sequencing (NGS), which simultaneously analyzes millions of DNA fragments, allowing for an entire genomic profile of a patient or their tumor. This type of technology can help identify multiple actionable mutations in cancer and allow doctors to select the most effective combination of therapies.
Liquid biopsies are another form of non-invasive advanced diagnostics that analyze a blood sample for circulating tumor DNA (ctDNA). This can be used to detect cancer early, monitor treatment effectiveness in real-time, or identify new mutations that may have developed after initial treatment, helping doctors adjust the therapy as needed.
Proteomics and metabolomics are also important fields of study within advanced diagnostics that focus on proteins and metabolites in the body. Because proteins and metabolites are continuously synthesized, transported, modified, and broken down over time (unlike genes), examining these substances in the body can offer a dynamic snapshot of a person’s health at a specific moment in time.
For example, proteomics can offer insight into which proteins are being expressed abnormally in a person with a particular disease, which can help researchers identify new targets for drug development and treatment.
Personalization in other fields
Personalized medicine is used in a variety of treatments for different health issues, but has made the most significant progress in oncology, allowing doctors to use genetic and molecular testing of a patient's tumor to select therapies that are most likely to be effective. For example, in patients with HER2-positive breast cancer, which is characterized by the overexpression of the HER2 protein, targeted therapies like trastuzumab (Herceptin) are available to specifically select for the HER2 protein, lowering the risk of cancer recurrence.
In the case of chronic myeloid leukemia (CML), the drug imatinib (Gleevec) also targets a specific protein, the BCR-ABL fusion protein, which is found in CML cells but not in healthy cells. And in non-small cell lung cancer (NSCLC), targeted therapies like crizotinib and osimertinib are used to treat patients with specific genetic mutations.
In addition to playing a pivotal role in modern oncology, personalized medicine is also used to treat other health conditions, such as cardiovascular disease and in a variety of rare illnesses. Through the use of pharmacogenomics, doctors can use genetic testing to determine how a patient will metabolize certain drugs. For example, testing for variations in genes like CYP2C19 can predict how a patient will respond to the blood thinner clopidogrel (Plavix), which helps doctors determine the correct dosage or an alternative medication to prevent heart attacks.
Genetic testing can also help confirm diagnoses for conditions like hypertrophic cardiomyopathy (HCM) and identify the specific genetic variant to help doctors choose the appropriate treatment and facilitate “cascade screening,” which offers genetic testing to relatives of the person diagnosed. In rare illnesses like cystic fibrosis (CF), personalized medicine resulted in the development of the drug ivacaftor (Kalydeco), which treats patients with a specific gene mutation, and in the case of HIV, personalized medicine helps predict a patient's response to antiretroviral therapy and identify those at high risk for developing drug resistance.
How personalized medicine applies to fertility
In the realm of fertility, personalized medicine allows fertility experts and specialists to use an individual's unique genetic, environmental, and lifestyle factors to tailor their treatments. Not only does this approach move away from the traditional one-size-fits-all model, but it’s been shown to increase the effectiveness and efficiency of treatments.
Individualized Diagnosis and Assessment
A cornerstone of personalized medicine in fertility is individualized diagnosis and assessment. This tailored approach moves beyond a standard protocol to create a customized approach for each patient. This process involves a comprehensive evaluation of both partners to pinpoint specific factors that may affect fertility.
Genetic screening in both partners is one crucial way to identify underlying genetic causes of infertility or a higher risk of passing on genetic disorders. Carrier screening tests for recessive genes that both partners may carry for disorders like cystic fibrosis or sickle cell anemia. If both are carriers, they have a higher risk of having a child with the disease. This information can inform decisions about using preimplantation genetic testing (PGT) during IVF to screen embryos.
Chromosome analysis (also known as karyotyping) checks for chromosomal abnormalities in both partners, which may be the cause of recurrent miscarriages or implantation failures. Identifying these issues helps in planning treatment and managing expectations.
There are also a range of tests used to assess fertility factors like ovarian reserve and sperm health that influence personalizing treatment protocols, particularly for IVF:
- Anti-Müllerian Hormone (AMH): AMH is a key indicator of ovarian reserve, i.e. the number of remaining eggs a woman has in her ovaries. A high AMH level might suggest a good response to ovarian stimulation for egg retrieval, while a low level can indicate a diminished reserve and may require a different protocol.
- Follicle-Stimulating Hormone (FSH): FSH levels are a traditional marker of ovarian function. Testing FSH levels on the third day of IVF may help provide more information about ovarian reserve. One study showed that individuals with low FSH levels on day 3 had a better chance of becoming pregnant with an IVF attempt when compared to people with higher FSH levels between 15 mIU/ml and 24.9 mIU/ml.
- Sperm DNA Fragmentation: This test measures the amount of fragmented DNA in sperm. Because high levels of fragmented DNA can lead to failed fertilization or recurrent miscarriages, this information can help in choosing the most effective fertility treatment.
Lifestyle profiling
Comprehensively evaluating each partner’s overall health and lifestyle habits can also inform which fertility treatments may be best and why. Lifestyle factors including diet, exercise habits, and stress levels can impact fertility, and personalized guidance on nutrition and exercise can improve outcomes. Because environmental factors including exposure to certain toxins or chemicals can also influence individual differences in fertility, taking a detailed history of each patient can help identify and mitigate these risks.
Finally, existing chronic health issues like polycystic ovary syndrome (PCOS), endometriosis, or thyroid disorders can all affect reproductive health and how a patient responds to fertility treatments, so evaluating and managing these conditions can help inform tailored treatments.
Tailored fertility treatments
Tailored fertility treatments are a key component of personalized medicine, helping to optimize each step of the process. By customizing protocols based on an individual's unique biological data, doctors can improve success rates and reduce risks.
IVF personalization
For example, tailored fertility treatments are a big part of IVF, which includes customized IVF stimulation protocols based on age, ovarian reserve, and hormone levels. In IVF, the ovaries are stimulated to produce multiple eggs, and personalized protocols tailor the type and dosage of medication to each patient. Older patients may require more aggressive stimulation protocol, as well as patients with a lower ovarian reserve.
By checking the levels of hormones like FSH and estrogen throughout the cycle, doctors are also able to adjust medication to ensure an optimal response and prevent complications like ovarian hyperstimulation syndrome (OHSS).
Embryo transfer timing
The timing of an embryo transfer is also another area of tailored fertility treatments that is critical to ensure the uterus is in its most receptive state. Endometrial receptivity array (ERA) is a genetic test that determines a patient’s specific window of implantation by analyzing a small tissue sample from the uterine lining. This sample informs the doctors of when the uterus is most receptive to an embryo, allowing for a personalized transfer schedule. This personalized protocol may be especially important for patients with a history of unexplained implantation failure.
Preimplanetation Genetic Testing
Preimplantation genetic testing (PGT) for embryos is another form of tailored fertility medicine that involves genetically screening embryos before they are transferred to the uterus. PGT helps doctors select the healthiest embryos to increase the chances of a successful pregnancy and a healthy baby. There are several types of PGT:
- PGT-A (Aneuploidy): This type of PGT screens embryos for chromosomal abnormalities, like an extra or missing chromosome. Transferring a chromosomally normal embryo can reduce the risk of miscarriage and increase IVF success rates.
- PGT-M (Monogenic/Single Gene Defects): This is used when there is a known risk of a specific single-gene disorder, like cystic fibrosis. It allows doctors to select embryos that are free of the disease, preventing its transmission.
- PGT-SR (Structural Rearrangements): This type of test is for couples with chromosomal rearrangements, like translocations, that can cause repeated miscarriages or infertility. PGT-SR helps identify embryos with a balanced set of chromosomes.
Personalization for male factor infertility
By going beyond a basic semen analysis to identify specific issues, personalized medicine can also be used to address male factor infertility with tailored treatments. Customizing treatment approaches makes it possible for doctors to provide a more precise approach, which can improve success rates.
While a standard semen analysis looks at sperm concentration, morphology (shape), and motility, advanced testing goes deeper to find the root cause of infertility. The sperm DNA fragmentation test, for example, measures the amount of fragmented or damaged DNA in sperm. High levels of fragmented DNA can lead to failed fertilization, poor embryo development, or recurrent miscarriages. By identifying this issue through testing, doctors may be able to choose the best course of action which may include lifestyle changes or specific ART techniques like intracytoplasmic sperm injection (ICSI).
Genetic testing for male partners is another important part of personalized fertility treatment that may help uncover specific mutations that cause infertility. One common example of male partner genetic screening is a test for Y-chromosome microdeletions, which are small deletions on the Y chromosome that can cause a complete lack of sperm production. By identifying this issue, doctors can rule out sperm retrieval as a viable option and instead find alternative fertility options.
Once a specific issue is identified through advanced semen analysis and/or genetic testing, personalized medicine can allow for targeted interventions to improve sperm quality. These may include:
- Dietary and lifestyle changes: Patients may be advised to make specific and tailored dietary, exercise, and/or stress management changes to optimize their fertility.
- Varicocele treatment: Varicoceles are enlarged veins in the scrotum that are a common cause of male infertility. While not all cases require intervention, doctors may recommend targeted treatment if advanced testing indicates the varicocele is having a significant impact on sperm quality. Typically, a procedure can help repair the varicocele to improve sperm parameters.
- Surgical sperm retrieval: For men with blockages or an inability to produce sperm, personalized treatment may involve surgical sperm retrieval, which includes techniques like testicular sperm extraction (TESE), is a targeted intervention that allows doctors to retrieve viable sperm directly from the testicle for use in an IVF procedure.
Lifestyle and environmental optimization
Diet, exercise, stress management, and environmental exposure are all key areas where personalized medicine can significantly improve fertility outcomes. Recommendations are not generic but are tailored to the individual or couple's unique health profile, lifestyle, and specific needs.
Nutrition plans
Dietitians and other trained medical experts can help develop nutrition plans that address specific conditions and nutrient deficiencies that may impact fertility. For example, patients with PCOS may be advised to focus on a low-glycemic or anti-inflammatory diet to regulate insulin levels and hormonal imbalances, while individuals with poor sperm quality may be advised to eat foods rich in antioxidants and specific nutrients like zinc and selenium. In some cases, experts may take into account a person’s blood work to optimize their reproductive health and recommend targeted supplementation with nutrients like folate, vitamin D, iron, or more.
Physical exercise plans
While general guidelines around physical activity exist, fertility experts may recommend specific, personalized exercise parameters to individuals based on a number of factors like health status, BMI, fitness level, and more. In some cases, over-exercising can negatively affect fertility, which a tailored plan can help prevent. Working with a professional who can provide personalized guidance around the type and amount of exercise to optimize fertility can help ensure the best possible results.
Stress management
Because stress can significantly impact fertility, personalized medicine can help identify and address a person's specific stress triggers. For some individuals, specific practices like mindfulness-based meditation may help manage anxiety, while others may benefit from cognitive behavioral therapy (CBT) or other methods. Depending on a variety of factors, different patients will require different types of mental healthcare, and personalized medicine can provide that level of individualization.
Environmental exposures
A personalized assessment of a person's environment may also be crucial for identifying and mitigating exposure to harmful substances. By asking about an individual’s occupation or hobbies, fertility experts can identify potential exposure to endocrine disruptors, pesticides, or heavy metals that can harm reproductive health. Based on these tailored assessments, experts can provide specific advice on how to reduce exposure, such as wearing protective equipment at work or avoiding certain household cleaning products.
Pros and cons of personalized medicine in fertility
Key technologies and approaches
By going beyond traditional methods of fertility treatment, modern technologies and approaches can further optimize every step of the process, from diagnosis to treatment, for each individual.
Genetic screening
Preimplantation genetic testing (PGT), also known as preimplantation genetic screening or PGS, is one type of advanced technology that enhances the treatment process by evaluating the health of a form of embryos created through IVF. It identifies genetic and chromosomal abnormalities before an embryo is transferred to the uterus.
Through the various forms of PGT (PGT-A, PGT-M, and PGT-SR), fertility experts can identify extra or missing chromosomes, specific inherited single-gene disorders, and chromosomal translocations. Finding these issues in the embryo can help explain infertility or pregnancy loss issues and help guide future treatment.
Individualized Controlled Ovarian Stimulation
Moving beyond a standard protocol for stimulating the ovaries to produce eggs, individualized controlled ovarian stimulation (iCOS) is another form of personalized fertility medicine that uses a patient’s unique biological data to tailor the dosage and type of medication.
By using hormonal and biomarker tests like anti-müllerian hormone (AMH) and antral follicle count (AFC) to assess ovarian reserve, doctors can create a specific stimulation plan to maximize the number of high-quality eggs retrieved while minimizing the risk of complications like ovarian hyperstimulation syndrome (OHSS).
Hormone monitoring
Throughout the IVF cycle, a patient's hormone levels are closely monitored to ensure the body is responding appropriately and optimally to treatment. Doctors continuously monitor hormones like estrogen and progesterone to make real-time adjustments to medication dosages. This prevents over- or under-stimulation, leading to a more controlled and effective cycle.
Embryo selection with time-lapsing
Beyond genetic screening, advanced technologies are also used to select the best embryos for transfer. Time-lapse imaging, for example, uses an incubator with a built-in camera to take continuous images of developing embryos. This allows doctors to observe their development without removing them from a stable environment and provides a detailed look at the embryo's timeline and morphology, helping to identify which may be best for implantation. Patients with recurrent implantation failure may benefit from endometrial receptivity array (ERA) which analyzes a small sample of the uterine lining to determine the best time to implant an embryo.
AI in predictive models
The future of personalized fertility medicine may be in advancements related to artificial intelligence (AI) and big data. For example, AI algorithms can now analyze vast amounts of data from thousands of patient cycles to build predictive models. These models can help doctors estimate the probability of success for a specific patient, identify key factors that might affect their cycle, and recommend the most effective protocols. However, while AI may enhance ART efficacy and personalization, there are a number of validation and ethical challenges to consider.
Challenges and ethical considerations
While tailored fertility treatments offer promising opportunities for optimized care, they also bring significant challenges and ethical considerations. One of the main challenges to consider is the high cost associated with personalized fertility treatments, which is a major barrier for many individuals and couples. These treatments, which include advanced genetic testing and AI-driven protocols, can cost significantly more than conventional IVF. This financial burden can create a disparity in access to care, limiting these advanced options to those who can afford them and raising concerns about healthcare equity.
Because personalized fertility treatments rely heavily on an individual's sensitive genetic and health data, these approaches may also raise serious privacy concerns. These personalized approaches hinge on the collection of highly personal data, including genetic profiles and reproductive health details, and properly securing this information is crucial. Additionally, working with this type of data may raise questions of ownership and how this information might be used in the future.
The technologies used in personalized fertility also raise a number of complex ethical questions. One such question relates to embryo selection. While PGT is meant to be used to screen for serious diseases, the technology allows for the selection of embryos based on genetic traits, which raises concerns about the potential for "designer babies" and selecting for non-medical traits like eye color or intelligence. The advent of technologies like CRISPR has introduced the possibility of editing genes within an embryo to correct genetic defects. While this could prevent inherited diseases, it also brings up ethical questions about unintended consequences, as well as the potential for human germline editing, which could affect future generations.
Personalized medicine also provides individuals and couples an unprecedented amount of information about their potential future child. The knowledge of this information could influence the decisions people make about which embryos to use or which genetic risks to accept, which can be emotionally and psychologically challenging.
The future of precision medicine and fertility
With ongoing research, emerging technologies, and a shift towards preventative care, personalized medicine is positioned to be the future of fertility treatments. The continued research discoveries and developments in care aim to make fertility treatments more effective and accessible for all patients while reducing the significant emotional burdens often associated with fertility journeys.
Ongoing research for new biomarkers and genetic indicators is helping to expand the field of reproductive science by providing more detailed pictures of patients’ fertility. Through innovations like non-invasive PGT, for example, doctors may be able to use DNA from a culture medium surrounding an embryo, eliminating the need for a biopsy. This method could make PGT safer and more accessible to a variety of individuals and couples. Additionally, studies are now identifying new genetic markers that can more accurately predict how a person’s ovaries will respond to stimulation medications. This development could potentially allow for even more precise, personalized protocols from the very beginning of an IVF cycle, optimizing results.
Artificial intelligence and machine learning are also setting the stage for a more precise and successful future in fertility treatments. By incorporating robust tools for decision decision support, these technologies are helping to ensure more specific, accurate treatment strategies. By analyzing vast datasets from thousands of fertility cycles, AI algorithms are able to predict the probability of fertility success for a specific patient. These predictions can help clinicians recommend the most effective treatment plan and avoid expensive and time-consuming trial-and-error. AI is also being trained to analyze time-lapse images of embryos to identify those with the highest potential for successful implantation. This method has the potential to provide improved accuracy, leading to better outcomes. Finally, AI can also be used to model various treatment protocols and their likely outcomes, which can help doctors choose the most efficient path for each patient, reducing the number of cycles needed.
The future of precision medicine and fertility is largely shaped by its potential for early risk identification, moving beyond traditional, generalized treatment in favor of tailored, preventive care. By identifying risks early, doctors can intervene before fertility becomes a major issue. For example, by making genetic screening more accessible, individuals and couples could make informed decisions around potential future fertility risks like Y-chromosome microdeletions or a rapid decline in ovarian reserve. Based on genetic and biomarker data, individuals could also receive personalized recommendations on diet, exercise, and environmental exposure to protect their reproductive health and potentially influence the choices they make in their personal and professional lives.
Frequently Asked Questions (FAQ)
What is personalized medicine in fertility?
Personalized medicine in fertility is a patient-centered approach that tailors treatments to a person’s unique biological and genetic characteristics.
