Could Iodine Deficiency Cause Loss of Libido and Erectile Dysfunction in Men?

Could Iodine Deficiency Cause Loss of Libido and Erectile Dysfunction in Men?

As you may know, we’re big advocates for the importance of iodine when it comes to supporting women’s health. However, iodine is also an essential nutrient many men are missing from their diet that could be harming their sex drive. Research has revealed that iodine deficiency could be the cause of erectile dysfunction and a low libido. You probably wouldn’t believe us if we said that seaweed could be the solution. Read on to find out how the essential nutrient iodine is just as important for men as it is women.

Symptoms of an Iodine Deficiency in Men  

Iodine is a vital nutrient that plays a role in many bodily processes yet deficiency is common which can cause hypothyroidism. Hypothyroidism occurs when the thyroid gland does not make a sufficient number of thyroid hormones causing unpleasant symptoms. This is an important health concern for many women, yet men also have a thyroid gland and therefore can develop hypothyroidism. In the UK, it affects 15 in every 1,000 women, and 1 in every 1,000 men (1). So, whilst it is more common in women, it's not something that should be overlooked in men. 

An underactive thyroid in men can present with symptoms such as hair loss, loss of muscle mass, depression, delayed or premature ejaculation, decreased sex drive and weight gain (2). Do these symptoms sound familiar? To take our two-minute quiz to find out if you are iodine deficient, click here. 

Iodine and Testosterone Levels 

Studies show that hypothyroidism can lower free testosterone levels in the blood as well as levels of sex hormone-binding globulin, a protein which carries testosterone round the body (3). Both contribute to low testosterone which can cause all these unwanted side effects. More notably, previous studies have also shown that an iodine deficiency was associated with decreasing semen quality and quantity which can cause fertility complications (4). This, along with erectile dysfunction and decreased sex drive makes it equally important that men have a sufficient iodine intake as women, to ensure a healthy thyroid and optimal sex life. 

The superfood that footballers Christiano Ronaldo and Lionel Messi swear by

If Ronaldo and Messi believe in it – it must be good! Seaweed could be the answer you’re looking for to give you that added boost of energy and lift your libido to help you function optimally. 

Why Seaweed is Your Sex Life Saviour
