How Your Thyroid Can Cause Period and Fertility Problems

There are numerous causes, which relate to the fertility issues in a woman and sometimes it is difficult to diagnose the true cause of such a problem. One of the most noticeable factors of all is the thyroid conditions.

Here, we are going to unveil the possible causes of fertility problems that are associated with a thyroid disorder.

The connection between Thyroid Issues and Infertility

The issue of hypothyroidism or underactive thyroid may lead to fertility problems and irregular menstrual cycles. Both hyperthyroidism and hypothyroidism cause trouble during ovulation. If no egg releases, there will be no menstrual cycle or period.


Thyroid and periods

Hypothyroidism is a condition where the thyroid gland fails to produce the desired amount of thyroxin.  When your body doesn’t make the required amount of thyroid hormones, this condition is known as the underactive thyroid. This disease affects a wide range of functions that our body performs. One of these is the menstrual cycle.

One of the most common causes of this particular condition is Hashimoto’s disease. During this disease, our immune system mistakenly attacks the thyroid. This attack reduces the ability to produce enough thyroid hormones.


During overactive thyroid or Hyperthyroidism conditions, the thyroid gland starts to produce an excessive amount of thyroid hormone. This disturbs the menstruation cycle and in most cases affects fertility. Besides, the increase in hormone production also speeds up the different functions of our body such as heart rate and metabolism.

The most usual cause of this condition is Graves’ disease. This disorder is associated with the malfunction of our immune system. The hyperthyroidism also causes issues with the ovulation process, ultimately disturbing the fertility and menstruation cycle.

Estrogen and its Impact

The women suffering from a thyroid condition or those taking birth control pills can experience a disturbance in the menstrual cycle. The intake of estrogen or birth control pills may increase the chances of infertility in most of the women.

Birth control pills also impact the liver, which creates thyroid-binding proteins. These proteins attach to the thyroid hormones. When you take birth control pills containing estrogen, the liver starts to produce additional protein.

Similarly, when you administer different hormonal medications that are made of estrogens, it affects the release of thyroid hormones. However, if you are administering the thyroid medication, the best way to adjust the amount of thyroid hormone is to alter the dose of your medication after consulting your doctor.

This suggests that a woman with hypothyroidism condition should talk to her doctor before taking birth control pills. Similarly, it is also advised to see your doctor when you want to conceive. As a result, your doctor will adjust your thyroid medication with reference to the requirement of the thyroid hormone.

How to Reduce the Risk

The best possible way to reduce the risk of infertility and health complications due to thyroid problems is to keep your thyroid condition under control. No matter whether you are suffering from hypothyroidism or hyperthyroidism, it is possible to successfully treat such conditions. You can overcome the infertility issue by taking care of your thyroid problems.
