The Role of Autoimmunity in Infertility and Pregnancy Complications

Infertility is a sensitive and often frustrating experience for many people, but it’s not always just about the inability to conceive. For some individuals, the underlying cause can be linked to autoimmune disorders, which can have a significant impact on fertility, pregnancy outcomes, and overall reproductive health.
In this blog, we highlight a podcast conversation between Dr. Amigues and Dr. Sarah Pederson, an OBGYN specializing in infertility, as they explore the connection between unexplained infertility and positive ANA.
What is ANA and How Does it Relate to Infertility?
ANA, or antinuclear antibodies, are a group of autoantibodies that target substances within the nucleus of cells. A positive ANA test is often associated with autoimmune diseases, including lupus, rheumatoid arthritis, and others. While having a positive ANA alone doesn’t mean someone has an autoimmune disease, it can be an early indicator of an underlying autoimmune process.
In recent years, studies have shown that women with a positive ANA test may have a higher chance of experiencing fertility challenges and pregnancy complications. The presence of these antibodies can affect fertility in various ways, including altering the quality of eggs, disrupting ovulation, impairing embryo implantation, and even increasing the risk of miscarriage.
When to Seek Fertility Evaluation?
In traditional terms, infertility is defined as the inability to conceive after trying for one year (or six months if you're over 35). However, it’s essential to note that fertility isn’t just about timing intercourse or using assisted reproductive technologies like IVF or IUI. It’s about optimizing overall reproductive health. If you've been trying to conceive for several months, and something just doesn't feel right—such as irregular periods, unexplained fatigue, or changes in your hormone levels—it might be time to consult with a fertility specialist.
Dr. Pederson, an OB-GYN specialized in infertility, emphasizes the importance of addressing subtle signs early on. These signs might include:
Irregular periods or spotting
Short luteal phase (the time between ovulation and menstruation)
Poor egg quality or low ovarian reserve
Fatigue, joint pain, rashes, or muscle pain
By taking a holistic approach, a fertility specialist can evaluate hormone levels, check for any signs of inflammation or autoimmune activity, and recommend treatments to improve fertility.
Autoimmunity’s Impact on Egg Quality and Ovulation
One of the most significant concerns related to autoimmune disorders and infertility is how they affect egg quality and ovulation. Autoimmunity can interfere with the recruitment of healthy eggs, disrupt hormonal balance, and ultimately make it harder to get pregnant. Conditions like lupus and undifferentiated connective tissue disease (UCTD) can lead to poor ovarian reserve, shorter menstrual cycles, and more challenges in the early stages of pregnancy.
For patients with a positive ANA, treatment often involves managing inflammation, balancing hormones, and, in some cases, addressing autoimmune triggers. It highlights the importance of looking at a patient’s overall health, including gut function, diet, and even nutritional status. For example, a diet rich in essential nutrients can help optimize hormonal balance and support egg quality.
The Role of Prednisone and Plaquenil in Fertility Treatment
When autoimmune activity is present, specialists may consider treatments like prednisone and Plaquenil (hydroxychloroquine) to reduce inflammation and improve fertility outcomes. Prednisone, a steroid, has been shown to double live pregnancy rates in women with a positive ANA. It works by suppressing inflammation and modulating the immune response, thus providing a more favorable environment for conception and early pregnancy.
Plaquenil, traditionally used to treat autoimmune conditions like lupus, has gained attention in the fertility world. Research suggests that taking Plaquenil during the first trimester can help reduce the risk of complications such as preeclampsia—a condition that causes high blood pressure and protein in the urine and can lead to premature birth or maternal health risks.
What About Diet and Gut Health?
A holistic approach to fertility often extends beyond medication. Gut health plays a critical role in hormone regulation and nutrient absorption. A well-functioning digestive system ensures that essential vitamins and minerals, such as B vitamins and protein, are available to support reproductive health.
Also emphasizes the significance of a nutrient-rich, anti-inflammatory diet. Low-dose naltrexone, an emerging treatment for autoimmune conditions, is sometimes used to help reduce thyroid antibodies and improve implantation rates in fertility treatments. Research in this area, especially from experts like Dr. Phil Boyle in NeoFertility, shows promising results for women with thyroid autoimmune diseases like Hashimoto’s.
A Personalized Approach to Reproductive Health
When dealing with infertility and autoimmune-related fertility issues, a one-size-fits-all approach doesn’t work. Each patient’s journey is unique, and a comprehensive fertility evaluation should include an analysis of their hormone levels, autoimmune markers, diet, and gut health.
For women with a positive ANA or other autoimmune conditions, it’s essential to work with a fertility specialist who understands the connection between autoimmunity and reproductive health. By taking a proactive approach, optimizing health before resorting to more invasive treatments, and managing inflammation early on, it’s possible to improve the chances of a successful pregnancy and a healthy baby.
If you're struggling with infertility and suspect an autoimmune component, don’t hesitate to reach out to a fertility specialist. With the right care and a holistic approach, there’s hope for a successful pregnancy even when autoimmune challenges are in play.
