The thyroid gland, located in the neck, is responsible for producing essential hormones called triiodothyronine (T3) and thyroxine (T4). When the thyroid gland produces insufficient hormones, a condition known as hypothyroidism, it can have various effects on the body. But how does hypothyroidism impact female fertility?
Causes of Hypothyroidism
Hypothyroidism occurs when the thyroid gland’s activity is reduced. Some common causes include:
Autoimmune thyroiditis (Hashimoto's disease): The immune system attacks and destroys thyroid cells, reducing hormone production.
Exposure to radioactive iodine treatment.
Thyroidectomy: Surgical removal of the thyroid gland.
Thyroiditis: Inflammation of the thyroid gland.
Certain medications.
Among these, autoimmune thyroiditis is the most common cause of hypothyroidism.
Symptoms of Hypothyroidism
Some of the most typical symptoms of hypothyroidism include:
Weight gain
Low tolerance to cold temperatures
Heavy or irregular menstruation
Swollen face
Hair loss
Constipation
Fatigue
Fertility issues
Diagnosis and Treatment of Hypothyroidism
Hypothyroidism can be diagnosed through a combination of medical history, physical examination, ultrasound, and blood tests (including TSH, free T4, free T3, and thyroid antibodies). Treatment is typically pharmacological, aimed at replacing the thyroid hormone that the gland can no longer produce.
Does Hypothyroidism Affect Fertility?
Yes, hypothyroidism can negatively impact fertility. Thyroid hormones interact with reproductive hormones such as estrogen and progesterone to maintain normal ovulation and egg maturation. When thyroid function is impaired, female reproductive health and fertility may also be affected. Studies show that hypothyroidism is linked to infertility and a higher risk of miscarriage.
