Although hormonal and fertility evaluations can impart profound knowledge, taking functional lab testing a step further can greatly inform the underlying causes of infertility. Functional lab testing assesses multiple physiologic markers that can help healthcare providers identify root causes of disease, supporting the ability to treat the cause and individualize treatment. Below, we discuss some functional lab tests used to identify the underlying causes of female infertility.
Exploring Functional Lab Tests for Female Infertility
1. Hormone Panel
A full hormone panel tests levels of the main sex steroids (estrogen and progesterone), gonadotrophs (follicle-stimulating hormone and luteinizing hormone), thyroid hormones, and prolactin. Differences in these hormones can indicate to the specialist possible hormonal imbalances affecting ovulation and fertility.
2. Thyroid Function Tests
Tests of thyroid function evaluate levels of thyroid hormones (T3, T4, and thyroid-stimulating hormone, or TSH), and understandably so since thyroid dysfunction can alter menstrual cycles and impair fertility. Therefore, thyroid testing is part of a basic infertility workup.
3. Anti-Mullerian Hormone (AMH) Test
AMH testing can indicate ovarian reserve or the number of eggs remaining in the ovaries. Low AMH levels indicate poor ovarian reserve, which can affect fertility and responsiveness to fertility treatment.
4. Ovulation Monitoring
Ovulation monitoring involves measuring hormonal changes as well as the growth of ovarian follicles, which contain the eggs during the cycle.’ Measures such as charting basal temperature, ovulation predictor kits, and ultrasound all can be used to identify ovulatory dysfunction and detect ovulation itself.
5. Nutritional and Micronutrient Testing
It could be nutritional deficiencies, causing hormone imbalances that may affect fertility, or it could be a nutrient imbalance. This is why an initial step in natural fertility treatment is comprehensive nutritional testing of various vitamins, minerals, antioxidants, and fatty acids; testing can help identify what specific deficiencies or imbalances a person has, which can then be addressed with personalized supplementation strategies.
Understanding the Role of Functional Lab Testing in Infertility Diagnosis
Functional lab tests offer a broader perspective on infertility and can help identify underlying issues that contribute to infertility by understanding a woman’s metabolism rather than just her hormone levels. These tests help analyze:
6. Inflammation and Immune Function
Dysfunction of the immune system and chronic inflammation can lead to infertility by disrupting ovarian function and implantation. Functional testing assesses markers of inflammation and immune dysfunction; targeted interventions to reduce inflammation and improve immune balance are formed based on these results.
7. Toxicant Exposure
Environmental toxins, heavy metals, and endocrine-disrupting chemicals compromise fertility by disrupting the hormonal balance necessary for normal reproductive function. Functional testing measures the level of toxin exposure, often guiding individualized detoxification protocols to minimize toxic burden and optimize fertility.
8. Gut Health and Microbiome Analysis
The gut microbiome influences hormone metabolism and immune function, and functional testing to assess markers of gut health and gut microbiome composition assesses for imbalances that may contribute to infertility. Identifying these imbalances can guide diet and lifestyle interventions to optimize gut health and fertility.
Conclusion: Empowering Fertility with Functional Lab Testing
These functional lab tests allow a more comprehensive approach to explore what is contributing to infertility, including approaches to correcting hormonal imbalance, assessing the function of the ovaries and adrenals, testing what are the nutrients in need of correction for optimal fertility, identifying how inflammation might be impacting fertility, to detecting what toxins might be harming fertility, as well as assessing gut health which is a critical component to optimizing fertility. Using functional lab testing alongside a comprehensive history and physical allows an individualized approach for enhancing fertility. When patients and clinicians have this information and use it wisely, then we can optimize fertility.
