Now, imagine you can no longer enjoy the mighty sexual drive in your life. It will indeed affect your personal life as well as your partner’s.

Most tend to consider a physiological issue or stress as its cause; seldom do you blame your thyroid for it. However, thyroid dysfunctionality is a significant cause of your poor sexual drive. Nevertheless, how thyroid and sex drive are related?

The thyroid is a butterfly-shaped gland in your neck that produces two primary hormones that control almost everything in your body, including your sex hormones. When your body experiences thyroid disorder, it often causes sexual dysfunction issues like low sex drive, painful intercourse, erectile dysfunction, and so on.

What is Thyroid?

The thyroid gland is an all-controlling hormones factory. From its abode, your neck, it regulates everything in your body- your temperature, heart rate, blood pressure, metabolism, weight, characteristics of your nail, skin, and hair, and many more. The two major thyroid hormones are thyroxine (T4) and triiodothyronine (T3).

The Pituitary releases thyroid-stimulating hormone (TSH) that stimulates the thyroid’s production and release T3 and T4 that to regulate the normal function of your body. Study shows that thyroid hormones are responsible for one-third of sexual problems people undergo that can gravely affect the quality of your sex life.

How are Thyroid and Sex Drive Related?

Though much research is needed, it is evident that thyroid disorder may severely affect your sexual life.

The two thyroid hormones, T3 and T4, usually control almost every cell, organ, and system in your body. They also influence several hormones (estrogen and testosterone levels) related to your sexual health and pleasure.

The two major thyroid disorders are Hypothyroidism ( low hormonal production) and Hyperthyroidism (high hormonal production). When your body suffers from any of these disorders, you may face several sexual dysfunctions like erectile dysfunction, vaginal dryness, low libido, delayed ejaculation, etc.

The researchers examined 12 studies that dealt with thyroid disease and sexual dysfunction in both males and females in a study. They found that 59% to 63% of men and 22% to 46% of women experienced sexual difficulties among patients with hypothyroidism.

For patients with hyperthyroidism, 48% to 77% of men and 44% to 60% of women encounter sexual dysfunction.

The study also suggests that decreasing estrogen and testosterone due to hypothyroidism may affect female fertility and reproduction. Low testosterone and estrogen affect your sexual desire, drive, and satisfaction too.

Another research shows that people with hypothyroidism might produce high levels of another hormone, prolactin. It can cause hypoactive sexual desire disorder (HSDD) – a condition where you no longer desire sex for an extended period.

Sexual intimacy is crucial between partners. It’s a special bond that any relationship special. However, this bonding may suffer due to thyroid disorder—especially hypothyroidism and hyperthyroidism.

Men with thyroid disorder are seen to encounter the following sexual dysfunction.

In 2008, a study found that among 71 men with thyroid problems, almost 79 percent had experienced erectile dysfunction.

Ejaculation Problems: Hypothyroidism and hyperthyroidism both can cause ejaculation issues in men.

According to the Sexual Medicine Society of North America (SMSNA), men with hypothyroidism have an increased risk of delayed ejaculation. On the contrary, if you have an overactive thyroid, you may have an increased risk of premature ejaculation.

Decreasing Sex Drive: A thyroid disorder may cause low testosterone that can lower your libido. Research also has shown that both hypo and hyperthyroidism decrease the sex drive in males.

In Female

  • Hypoactive Sexual Desire Disorder (HSDD): This condition of hypothyroidism and low sex drive where women no longer think or desire sex for several months. It happens due to the overproduction of prolactin, the lactation hormone. It may cause personal distress or difficulties in her relationship.
