Sometimes, Thyroid Issues and Female Infertility is a source of great emotional distress for many women and couples. Although there are many medical conditions that can be responsible for infertility in females, thyroid disorders tend to be one of the most ignored and undiagnosed factors behind this problem. As we know, the thyroid is a hormone-sensitive organ and regulates metabolic processes, ovulation, menstruation, energy balance, and other important functions.

It is essential to understand how thyroid problems can affect the possibility of conceiving and maintaining a pregnancy. Fortunately, if a patient gets diagnosed with some thyroid condition that prevents her from getting pregnant, the chances for conception can be restored.

 What Is the Thyroid Gland?

This endocrine organ is located on the neck and responsible for regulating the following processes:

* Production of hormones thyroxine (T4)
* Synthesis of hormones triiodothyronine (T3)

The hormones secreted by the thyroid gland help regulate the following functions:

* Energy production
* Heart beating rate
* Body temperature regulation
* Ovulation
* Menstruation
* Pregnancy

The thyroid hormones are closely linked to those produced by reproductive organs (estrogen, progesterone, LH, FSH).

Effects of Thyroid Dysfunction on Fertility

Any thyroid malfunctioning can cause the imbalance of thyroid hormones that, in turn, leads to different types of fertility problems. Women who struggle with some thyroid condition have increased risks of developing:

* Irregular menstruation
* An ovulation
* Poor egg quality
* Miscarriages
* Conceiving difficulties

The list includes both hypothyroidism and hyperthyroidism.

Hypothyroidism and Infertility Problems

What Is Hypothyroidism?

This condition occurs when the thyroid gland fails to synthesise enough amount of hormones.

Common Causes

* Autoimmune disorder
* Hashimoto thyroiditis
* Iodine deficiency
* Post-surgery conditions
* Radiotherapy
* Medications

Hyperthyroidism and Fertility Issues

What Is Hyperthyroidism?

Hyperthyroidism occurs when the endocrine gland secretes too much hormones.

Common Causes

* Graves’ disease
* Thyroid nodules
* Thyroiditis
* High iodine intake

Symptoms of Hyperthyroidism

Women with hyperthyroidism experience the following symptoms:

* Fast heartbeat rate
* Anxiety
* Weight loss
* Sleeplessness
* Tremors
* Heat sensitivity
* Missed periods
* Excessive sweating

Effects of Hyperthyroidism on Fertility

Excessive amounts of hormones synthesised by the thyroid glands also influence the reproductive process. Some fertility complications caused by hyperthyroidism include:

* Irregular period
* Difficulties with conception
* Ovulatory disorders
* Implantation failure
* Pregnancy complications

 Thyroid Antibodies and Infertility

There might be cases when a woman will not have any thyroid hormone imbalances; yet, she will struggle with her fertility, since she will suffer from autoimmune thyroid disease.

The Most Common Thyroid Antibodies Are the Following Ones:

– Thyroid peroxidase antibodies (TPOAb).
– Thyroglobulin antibodies (TgAb).

They are related to:

– Recurrent miscarriages.
– Implantation failure.
– IVF complications.
– Pregnancy loss.

Hashimoto’s thyroiditis is directly connected with infertility in women and pregnancy complications.

The Thyroid and Menstrual Cycle Disorders

The thyroid gland influences the menstrual cycle as it interacts with estrogen and progesterone.

Possible Consequences of Thyroid Imbalance Might Be:

– Heavy periods.
– Scanty bleeding.
– Missed periods.
– Frequent cycles.
– Periods with pain.

Irregular period always means ovulation problem; therefore, a woman will experience difficulties while trying to conceive.

Can Thyroid Problem Result in PCOS?

Sometimes yes. Thyroid disorders may be characterized by PCOS-like symptoms which consist of:

– Irregular periods.
– Unexplained weight gain.
– Issues with ovulation.
– Fertility issues.

It is necessary to test patients for both disorders, since PCOS and thyroid dysfunction can coexist at once.

Perfect Levels of Thyroid Hormones for Fertility

In order to conceive, a lot of fertility doctors recommend maintaining the following thyroid levels:

– TSH levels less than 2.5 mIU/L.
– Stable thyroid hormone levels before becoming pregnant.

Normal thyroid hormones guarantee the possibility of:

– Proper ovulation.
– Successful fertilization.
– Implantation.
– Fetal growth.

 Management of Thyroid Fertility Issues

Fortunately, thyroid-infertility problems are usually easily manageable.

Treatment of Hypothyroidism

 Levothyroxine Therapy

Levothyroxine treatment is synthetic thyroid hormone therapy.

Advantages are:

– Regular ovulation.
– Normalised periods.
– Increased chances of conceiving.
– Decreased risks of miscarriage.

 Treatment of Hyperthyroidism

Depending on the degree of the condition, a patient might have to go through:

– Antithyroid medication.
– Radioiodine therapy.
– Surgery.

Specialists will closely watch thyroid hormones before and during pregnancy.

Lifestyle Adjustments for a Better Thyroid and Fertility

Certain lifestyle practices may help you have better thyroid and reproductive functions.

Recommendations Regarding Healthy Lifestyle Habits

Balanced Nutrition

Diet should include:

– Selenium.
– Zinc.
– Iron.
– Iodine.
– Omega-3 fatty acids.

Healthy Body Mass Index

Excess body fatness and underweight increase the risk of having an unbalanced hormone.

CONCLUSION

It is safe to say that there is a powerful connection between infertility and thyroid problems. As thyroid hormones influence ovulation, menstruation, and healthy pregnancies, any thyroid imbalance can have negative effects on fertility. On the positive note, however, it should be stated that thyroid diseases are among the most treatable health problems.

When a woman faces fertility problems, she must undergo comprehensive examination and check her thyroid hormones’ levels. Timely treatment will not only help improve fertility but also lead to healthier pregnancy outcomes.
