can hyperthyroidism cause infertility، The first step in diagnosing what prevents a woman from becoming pregnant is to conduct a fertility study that includes different tests, including thyroid analysis. The thyroid is a gland that is found in the neck and whose function is to regulate the metabolism. But in addition, the thyroid gland plays a fundamental role in reproductive function. Hyperthyroidism and hypothyroidism, if not treated, can affect both fertility and the development of the fetus, increasing the risk of miscarriage.

What is the thyroid good for?
The function of the thyroid gland is to control the metabolism. It secretes hormones abroad that are responsible for measuring the body’s response to other hormones. They are classified into two main groups: hyperthyroidism and hypothyroidism.
Hypothyroidism : occurs when the thyroid gland does not produce enough thyroid hormones to meet the body’s needs. This causes the metabolism to be slower.
Hyperthyroidism : with this condition, the thyroid gland produces excessive amounts of thyroid hormones and causes the metabolism to accelerate.
How do thyroid hormones affect fertility?
These alterations in the thyroid gland are frequent in young women between 25 to 45 years. However, it is not an exclusive complication of women, but male fertility can also be impaired.
In the case of women, the thyroid hormones interact with the female sex hormones – estrogen and progesterone – to maintain the normal functioning of the ovaries and the maturation of the ovules. The excess (hyperthyroidism) or defect (hypothyroidism) of thyroid hormones results in problems to achieve a pregnancy or carry a pregnancy to term, spontaneous abortions, problems in pregnancy and premature birth. In addition, they are associated with anovulation and abnormal menstrual cycles.
How to get a healthy pregnancy?
The diagnosis is essential for a healthy pregnancy and to receive appropriate treatment and regular monitoring, both women and men. The alterations of the thyroid can be regulated with medications that, in addition to controlling the level of thyroid hormones, restore fertility and, once the woman is pregnant, helps her normal pregnancy.
When a woman has problems conceiving due to a fertility problem, she is recommended to take iodine. Too low levels of iodine in the diet can cause low activity of the thyroid gland (hypothyroidism). For this, it is advisable to ingest recommended amounts of iodine, found in foods such as fish, bread, cheese, cow’s milk and eggs.
What are hypothyroidism and hyperthyroidism?
The thyroid is a butterfly-shaped gland that is located in the front of the neck, below the Adam’s apple.
It produces, stores and releases two hormones that regulate the body’s metabolism: T4 or thyroxine and T3 or triodothyronine.
Thyroid disorders can affect any of the body’s organic systems and are eight times more common in women.
They are classified into two major groups: hypothyroidism and hyperthyroidism.
Hypothyroidism is the result of a decrease in the activity of the thyroid gland, which does not produce enough hormones and makes the metabolism slow down.
On the other hand, hyperthyroidism is a consequence of the hyperactivity of the thyroid gland, which secretes excessive amounts of thyroid hormones and causes the metabolism to accelerate.

Sensitivity or heat intolerance
Frequent bowel movements
Nervousness and anxiety
Tremor in the hands
