The role of thyroid hormones in fertility

hormonas tiroideas y fertilidad

Thyroid hormones play an important role in fertility and the ability to get pregnant. These small butterfly-shaped glands in the neck are responsible for regulating metabolism and maintaining a proper balance in our bodies. This is essential for general health, but especially for reproductive function.

An imbalance in thyroid hormones can lead to changes in the menstrual cycle, including irregular or absent periods, which can make it difficult to conceive.

Therefore, if you’ve been trying unsuccessfully to conceive for some time, and you suspect that this may be related to a thyroid imbalance, it’s advisable to consult a fertility doctor so that they can study your case and determine the best options for you to become a mother.

HOW DO THYROID HORMONES WORK?

Thyroid hormones are produced by the thyroid gland. Specifically, thyroxine (T4) and triiodothyronine (T3) are responsible for regulating metabolism, affecting how our bodies produce and use energy. They also play a crucial role in the development and functioning of other systems, including the reproductive system.

Maintaining the right balance of these hormones is therefore essential for your body to function optimally, and for you to conceive and have a healthy pregnancy.

HOW DO THYROID HORMONES AFFECT FERTILITY?

The reproductive system is highly dependent on our hormones maintaining an optimal balance. Firstly, because thyroid hormones affect egg maturation in women and sperm production in men.

They also affect the regularity and length of menstrual cycles. An imbalance in thyroid hormones can lead to irregular menstrual cycles or absence of menstruation, known as amenorrhoea. This can make it harder to know when your fertile days are, and make it more difficult to get pregnant.

On the other hand, they also affect the lining of the uterus, which is essential for embryo implantation.

It’s also worth noting that thyroid disorders can cause problems with ovulation, which directly affect fertility.

HYPOTHYROIDISM AND FERTILITY

Hypothyroidism is a common thyroid disorder in which the thyroid gland does not produce enough thyroid hormone. People with this condition often experience irregular menstrual cycles, low libido and problems with ovulation. It also usually affects the quality of the eggs and the lining of the womb, which can make it difficult for the embryo to implant.

HYPERTHYROIDISM AND FERTILITY

Hyperthyroidism causes the thyroid gland to produce too much thyroid hormone, usually resulting in an increased heart rate, nervousness and unexplained weight loss. This can disrupt the menstrual cycle and make it difficult to conceive. It can also significantly increase the risk of complications during pregnancy.

THE IMPORTANCE OF CORRECT DIAGNOSIS AND TREATMENT TO IMPROVE FERTILITY

If you think you may have a thyroid disorder and are trying to get pregnant, you should see your doctor. A blood test to measure thyroid hormone levels will enable a specialist to make a correct diagnosis and recommend appropriate treatment.

Treatment for thyroid disease usually involves medication to restore hormone balance and ensure optimal levels before and during pregnancy.

It’s also important to have regular check-ups and blood tests, as well as a healthy lifestyle, including a balanced diet and regular exercise. Also try to avoid stress as far as possible, as this is a factor closely linked to fertility.

In summary, thyroid hormones play an important role in fertility and the ability to conceive. Thyroid disorders can affect menstrual cycles, ovulation and egg quality, making it difficult to conceive. However, with proper care and maintenance of an optimal hormonal balance, it’s possible to achieve a successful pregnancy.
