Is Your Immune System Stopping you From Getting Pregnant?

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.

Studies show that at least 10 to 20% of women who are unable to conceive are affected by some degree of immune disorder. These disorders may present themselves in the form of Endometriosis, Thyroid Disorders, or Celiac Disease. (1)

What is Autoimmune Malfunction?

An individual is said to be suffering from an autoimmune Disorder when their immune system starts attacking their own body cells.

These autoimmune disorders may be caused by a number of factors which include genetic factors, infections, and certain environmental conditions and exposures. Moreover, these disorders may also exhibit symptoms concentrated around a specific organ, or they may involve multiple body systems. Some commonly encountered autoimmune conditions include:

  • Systemic Lupus Erthmetosis
  • Type 1 Diabetes Mellitus
  • Multiple sclerosis
  • Scleroderma
  • Rheumatoid Arthritis
  • Thyroiditis.

Emerging research has also shown the involvement of autoimmune orders in certain conditions like Schizophrenia, IBS, and Infertility. (2)

The Association Between Autoimmune Malfunction and Female Fertility

Infertility caused by the immune system is associated with the involvement of a number of reproductive immune antibodies. These antibodies include the anti-sperm antibody, anti cardiolipin antibody, anti endometrial antibody, anti egg cell antibody, anti chorionic gonotropin antibody, and anti permeability belt antibody.

immune system and fertility

For example, the anti sperm antibody is usually produced in response to sperm, which is perceived as an antigen stimulant. The production of the anti sperm antibody has the potential to affect the movement of the sperm and its ability to reach the cervical region, which in turn leads to infertility. (3)

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. (4)

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. 


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.

Immune System and Fertility

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.  (9)

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. (10)


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.
