Infertility can be defined as when a couple have been trying for more than 12 months and have not been able to conceive. This can be caused by a number of factors, among which could include suffering from an autoimmune disorder.
Could your immune system be affecting your ability to get pregnant? Emerging research suggests that immune dysfunction, inflammation, and autoimmune conditions may play a role in unexplained infertility, recurrent miscarriage, implantation failure, and endometriosis.
In some women, the immune system may mistakenly react against reproductive tissues, affecting implantation, hormone balance, egg quality, or early pregnancy support.
According to Traditional Chinese Medicine (TCM), fertility depends on the balance between circulation, hormones, stress regulation, immune health, and overall wellbeing. When these systems fall out of balance, it may become more difficult for the body to support conception and pregnancy naturally.
What Is Immune-Related Infertility?
Infertility is generally defined as the inability to conceive after 12 months of regular unprotected intercourse.
Immune dysfunction may affect fertility in a significant number of women experiencing unexplained infertility or repeated pregnancy loss. Autoimmune-related fertility issues are commonly associated with chronic inflammation, hormonal disruption, and abnormal immune responses affecting the reproductive system. An autoimmune disorder occurs when the immune system mistakenly attacks the body’s own healthy tissues.
These conditions can be influenced by:
- Genetics
- Chronic inflammation
- Infections
- Stress
- Environmental issues
- Gut health and digestive imbalance
Some autoimmune conditions linked to fertility challenges include:
Research has also explored possible links between immune dysfunction and recurrent miscarriage, implantation failure, and unexplained infertility.
How the Immune System May Affect Fertility
The immune system plays an important role in implantation and early pregnancy development. In some cases, abnormal immune responses may interfere with: Embryo implantation, Endometrial receptivity, Hormonal communication, Ovarian function and Blood flow to the uterus.
In Traditional Chinese Medicine (TCM), the immune system is not viewed as a separate biological defence network in the same way as in Western medicine. Instead, it is closely linked to the body’s overall balance of Qi (energy), Blood, Yin, Yang, and the smooth functioning of the organ systems.
Rather than describing “autoimmune disease” directly, Chinese Medicine interprets immune-related fertility issues as a combination of:
- Internal inflammation (Heat)
- Weak Qi and Blood
- Poor uterine circulation
- Stress-related Liver Qi disruption
- Reduced Kidney energy
These patterns may overlap in women experiencing:
- Unexplained infertility
- Recurrent miscarriage
- Failed IVF implantation
- Endometriosis
- Irregular menstrual cycles
When these patterns coexist, the uterine environment may be considered less “nourishing” for implantation. From a Traditional Chinese Medicine (TCM) perspective, immune imbalance may influence fertility by disrupting several key reproductive processes at the same time.
This can include reduced endometrial receptivity, where the uterine lining is less able to support implantation, as well as impaired blood flow to the uterus and ovaries, which may affect nourishment of the reproductive organs. It may also interfere with hormonal communication between the brain and ovaries, impacting egg development and maturation, as well as the stability of implantation and early pregnancy support.
Endometriosis and Autoimmunity
Individuals with autoimmune disorders are frequently reported to be affected by endometriosis, miscarriages, and failed IVF treatments.
Studies have shown the individual affected with endometriosis to have significantly higher rate of production of anti endometrial antibodies compared to healthy individuals. This increased number of antibodies leads to a greater chance of them reacting with the endometrium. This reaction leads to activation of the immune system, which leads to significant endometrial and oviduct damage, negatively impacting the implantation of the embryo.
From a Traditional Chinese Medicine perspective, endometriosis is often understood in terms of underlying patterns such as Blood stasis, Qi stagnation, Damp Heat, and disrupted circulation within the uterus and pelvis. These imbalances are believed to affect the smooth flow of Blood and Qi, contributing to pain, inflammation, and reduced reproductive function.
The Role of Natural Killer Cells in Fertility
Natural Killer Cells play a significant role in the female fertility cycle, and irregularities in the number or function of these cells can impact one’s ability to conceive greatly. Their significance can be estimated by the fact that they make up at least 70% of the leukocytes found in the endometrium during embryo implantation and secretory phases (5). The Natural Killer cells are able to affect the implantation of the trophoblast due to their influence on the remodeling of the spiral artery – which is involved in the implantation process. (6)
The association between Natural Killer Cells and female fertility was further proven by studies that concluded by proving an increased risk of infertility in individuals which a higher number of these cells. (7)
The dysregulation of these cells is also found to exist in individuals with Endometriosis, which were found to have abnormalities in the maturation of these cells and reduction in endometrial stem cell factors.
The positive association between Natural Killer Cells abnormalities and Endometriosis and an increased number of these cells in infertile females have proven these cells to play a major role in female fertility. (8)
Ways to Alter One’s Immune System to Support Fertility
Theories introduced by Traditional Chinese Medicine suggest that infertility in females is usually caused by disruptions in the blood circulation, vital balance, and inhibition of Qi energy.
Acupuncture
An effective way to improve this is Acupuncture Therapy which involves the insertion of tiny sterile needles into specific acupuncture points of the body. This is hypothesized to not only regulate the body functions but also improve one’s fertility and increase their chances of conceiving.
Studies have found Acupuncture treatment helps:
- Balance the hormones in the body, facilitate better blood and energy flow, cause stimulation of the nervous system.
- Help strengthen one’s immunity and facilitate the removal of stasis and phlegm. Its ability to regulate blood flow allows an increased blood supply to the endometrium and improvement in the function of the follicles and ovaries.
- Acupuncture is now proven to be an effective therapeutic form for improving one’s fertility by balancing out the hormones and improving the function of sperm and ovaries.
Stress Reduction
Stress is another factor that is often associated with infertility. Even though it was previously believed to be a topic of debate where some experts did not believe it to have any impact on one’s fertility, numerous studies have since proven the contrary.
Studies have shown women with fertility problems to be diagnosed with increased levels of anxiety, stress, and depression, proving the association between the two. Hence Stress reduction by means of meditation, mindfulness practices, and yoga is an effective way to create a positive space for oneself and improve the chances of getting pregnant.
Diet
Certain lifestyle factors, including diet, smoking, alcohol consumption, and the intake of caffeine, may also have a direct impact on the reproductive system, and alterations in these factors can affect one’s fertility. Consuming an unbalanced diet on a daily basis has the potential to alter the bodyweight exponentially, which in turn leads to alterations in ovarian functions.
Studies have shown overweight females with a high BMI to be associated with greater chances of adverse outcomes to their pregnancies like miscarriage, preterm labour, and gestation diabetes. This highlights the importance of the correct diet in females of childbearing age and how essential it is that the diet contains the right levels of proteins, vitamins, healthy fats, and carbohydrates.
Referring to an Expert
