Are My Thyroid Issues Causing Erectile Dysfunction?

Although there are many potential causes of erectile dysfunction, scientists reported that one common cause - thyroid hormonal imbalance – is often ignored. This article aims to discuss the role of the thyroid hormone, how its imbalance causes ED, and how it could be treated.

What Is the Role of Thyroid Hormone?

The thyroid gland is a tiny butterfly-shaped gland found near the base of the neck region. It produces hormones responsible for overall body metabolism. Other functions of these hormones include the control of blood pressure, heart rate, and body temperature.

In fact, thyroid hormones play crucial roles in every function of the body. So, any alteration in their levels may cause various health issues, where erectile dysfunction is one among them.

How Thyroid Imbalance Causes ED?

Hormonal imbalance of the thyroid gland leads to two issues:

  • Hyperthyroidism – It is an overactive thyroid condition where the thyroid gland secretes too much hormone.
  • Hypothyroidism – It is an underactive thyroid condition where the thyroid gland does not secrete adequate hormones.

Both these conditions can affect men’s ability to achieve an erection. Other symptoms include low sex drive, mood fluctuations, and fatigue. 

During thyroid issues, your testosterone (the male sex organ) level will also come down which in turn reduces your sex drive. Mechanistically, both these conditions affect circulating sex hormone levels through central and peripheral nerve pathways. Furthermore, thyroid problem can indirectly affect your psychological stability that can affect your sex life.

Scientists are not yet clear about the exact relationship between thyroid disorder and erectile dysfunction.

A 2008 research article reported that 79% of people with thyroid dysfunction have ED, among which 37.5% of patients have severe ED.

According to the 2019 review article, researchers reported that although both these conditions are associated with ED, hypothyroidism is more connected to delayed ejaculation. On the other hand, hyperthyroidism is more connected to premature ejaculation.

Is Thyroid Imbalance the Most Common Cause of ED?


A 2006 research study revealed that ED was more prevalent in thyroid patients compared to obese and diabetic patients. This study also showed that thyroid issues are more frequently the cause of ED than aging. 

Is It Possible to Treat Thyroid Disorder-induced ED?


Fortunately, it is possible to treat thyroid disorder-induced ED. There are medications available for thyroid issues. Consult your doctor and discuss your symptoms so that he/she will recommend the appropriate treatment for you. 

In fact, erectile dysfunction is more common among males with hypothyroidism. Levothyroxine, a synthetic form of thyroxine (T4 thyroid hormone), is the standard drug prescribed for hypothyroidism.

A 2018 research study reported that males with sexual dysfunction and hypothyroidism experienced an improvement in their ED symptoms after consuming levothyroxine drugs. In case the patient is already consuming thyroid medication, this treatment can be tweaked to find more improvement in sexual function.

In severe cases, you may have to take radioactive iodine to destroy the gland or get it removed surgically. Both these options will stop hormone production. In that case, you should consume thyroid hormone replacement medication for your lifetime.

A 2008 research article concluded that erection issues will disappear by themselves once the thyroid disorder gets treated. Hence, screening for thyroid issues was highly recommended for males with ED. 

Is Taking Viagra (Or Other ED Medications) With Thyroid Medications Safe?


Phosphodiesterase-5 (PD-5) inhibitors like Viagra (sildenafil) can effectively treat erectile dysfunction and do not cross-react with thyroid treatments. Furthermore, a 2017 research article reported that the L-thyroxine treatment benefits hypothyroid men with sexual dysfunction.

Since thyroid issues might be responsible for ED, the researchers suggested that the specific treatment for ED should be delayed for a minimum of 6 months after achieving a normal level of thyroid secretion, as reported in the 2008 study.
