Does Hyperthyroidism Cause Infertility in Women and Men?

Hyperthyroidism refers to excessive production of thyroid hormone from thyroid glands. As thyroid hormone is one of the main hormones controlling various functions in our body it also directly affects fertility. Therefore, it is important to understand that hyperthyroidism can be a major cause of infertility. The good news is fertility problems linked to thyroid issues can easily be managed with antithyroid drugs.

Thyroid Disorders and Fertility: Understanding the Connection

Hormonal imbalances causing infertility is not something unusual to hear. One of the major reasons for infertility is hormonal imbalances most commonly thyroid hormone imbalance. Thyroid hormone controls all the important functions in our body– metabolism, temperature, growth and development and reproduction. Thyroid hormone imbalances therefore deteriorates overall health of an individual and also reproduction.

In hyperthyroidism, the thyroid gland produces excessive thyroid hormones. Hyperthyroidism in women can cause irregular periods, absent menstruation or decrease blood flow and even problems with conception. Most females are tested for hormonal imbalances when evaluating the effects of hyperthyroidism on conception.

In males hyperthyroidism causes low sperm count, poor sperm motility and sexual dysfunction. It is important to get a hormonal profile of the male partner as it is often overlooked.

Diagnosis and Treatment of Thyroid- Related Infertility

It is not very difficult to diagnose hyperthyroidism as many patients present with some common symptoms along with infertility. These symptoms include heat intolerance, excessive sweating, palpitations, rapid weight loss and diarrhoea. If any of the signs and symptoms of hyperthyroidism are present in any of the partners it is important to rule out imbalances in thyroid hormone. At Njinsky IVF & Fertility Clinic, our doctors diagnose hyperthyroidism through a routine blood test after a detailed history and examination.

The specific indicators for detecting hyperthyroidism are:

• TSH (Thyroid-stimulating hormone) – the most important initial screening test
• Free T4 levels to assess production of thyroid hormone
• Thyroid antibody tests- to detect autoimmune thyroid disease

Infertility treatment caused due to hyperthyroidism can be treated with antithyroid medications such as methimazole and propylthiouracil. Female infertility treatment with antithyroid drugs over a period of time brings fertility back to normal and women are often able to conceive naturally.

Antithyroid drugs are also used in male infertility treatment. However, if drugs are not effective doctors at Njinsky often recommend radioactive iodine therapy or surgery. During the treatment of hyperthyroidism our doctors monitor fertility progress by repeating semen analysis to check sperm count, sperm motility and morphology.

To conclude, early diagnosis and proper treatment of thyroid disorders are essential for improving fertility outcomes. Managing thyroid hormone levels not only increases the chances of conception but also supports a healthy pregnancy. At Njinsky IVF & Fertility Clinic we monitor progress along hormonal therapy to help you achieve pregnancy. We even offer Assisted reproductive techniques such as IVF, IUI and ICSI who are suffering from infertility despite proper treatment of hyperthyroidism.

Maintaining normal thyroid function is therefore an important part of reproductive health and infertility management.
