The thyroid gland is an endocrine gland in the front of the neck that produces thyroid hormones to regulate the body’s metabolism. Through the hormones it produces, the thyroid gland influences almost all of the metabolic processes in your body. The relationship between thyroid and infertility is impacted if your hormones become imbalanced, it can have a negative impact on reproductive health, making it difficult to achieve a pregnancy.
4 Ways Thyroid and Infertility are Related
If you have hyperthyroidism (overactive thyroid), the thyroid gland produces too many hormones. If you have hypothyroidism (underactive thyroid), the thyroid doesn’t produce enough hormones. In both situations, researchers have found a direct correlation with these hormone imbalances and infertility.
2). Low Levels of a Thyroid Hormone
Inadequate levels of a thyroid hormone can prevent ovulation or an egg from being released for fertilization. If there is not an egg present, conception cannot occur.
3). Underactive Thyroid
Aside from having difficulty conceiving, an underactive thyroid can pose challenges for carrying a pregnancy to full term. Women with hypothyroidism are more susceptible to miscarriages compared to women with normal hormone levels.
4). General Thyroid Disorders
In some cases, thyroid disorders can be overlooked especially in patients with a diagnosis of unexplained Infertility. These cases are sometimes dismissed as being due to stress or psychological issues, so it’s important for physicians to ask the right questions and conduct appropriate tests to see if thyroid disease could be a contributing factor. At Shady Grove Fertility, as part of a patient’s initial workup, we perform a series of hormonal testing to determine any causes for a person’s infertility. Our physicians perform these tests because hormones control every step of achieving a pregnancy. Based on the results, our physicians then determine an appropriate treatment plan for your individual needs.
When to Seek Help
It is recommended to seek a full thyroid evaluation if you have experienced:
• Inability to conceive after 1 year if you are less than 35 and 6 months if 35 or older
• Two or more miscarriages
• Irregular menstrual cycles
• Family history of thyroid disorders
There are other reasons why a person might have infertility that might not be attributed to thyroid disease. However, if symptoms of hypothyroidism or hyperthyroidism are present, we recommend a thyroid screening.
Once underlying thyroid issues are treated, generally with medication, and hormones return to adequate levels, a women’s fertility may be restored. If this is not the case, it’s important to seek help from a reproductive endocrinologist to see if there are any other underlying factors as to why pregnancy has not occurred.
NOTE: It is observed in Hashimoto’s thyroditis increase of the markers anti-TG and anti-TPO, so these women that suffer from this disease, they either remain infertile, either have RSAs in the first trimester of their pregnancy because our center has proven that they have high NK cells, endometrial NK cells, and NK activity. Our center offers targeted individual therapy and regulates all 3 NK markers in women that suffer from thyroid problem or Hashimoto’s thyroditis and they have a good chance to become pregnant naturally or with IVF.
