Testosterone and Your Thyroid

Testosterone and Your Thyroid

STEP 1: Many men start yawning almost immediately when you bring up anything to do with the thyroid, but that really should not be the case. The thyroid is somewhat like the floor pedals (accelerator/brake) on your car, since the thyroid either slows down or speeds up hormones and metabolism. For example, low thyroid function (hypothyroidism) is associated with lower testosterone and elevated thyrooid function (hyperthyroidism) with increased testosterone.
Now on this page I am going to concentrate on hypothyroidism for the simple reason that the symptoms are so common on the Peak Testosterone Forum. A very high percentage of men coming to the forum have the classic symptoms of low thyroid function such as fatigue, poor libido, depression and erectile dysfunction. (For more information on the latter, see my link on Erectile Dysfunction and the Thyroid.) From my perspective, it is almost an epidemic and I want to cover some of the basics below.
However, let’s start by looking at the evidence that hypothyroidism actually lowers testosterone:
1. Decreased LH (Leutinizing Hormone). Researchers have found that hypothyroid men have a “subnormal response of luteinizing hormone (LH) to gonadotropin-releasing hormone (GnRH) administration.” [1] Of course, GnRH is produced by the hypothalamus, which then triggers LH. LH, in turn, stimulates the testes to produce testosterone. This means that hypothyrodism sabotages the first step in the testosterone production assembly line.
2. Decreased Free Testosterone Levels. The same study and others have noted that hypothyroid men tend to have lower free testosterone concentrations. [1][2]
3. Treating Hypothyroidism Often Increases Testosterone. A further sign of hypothyroidism’s causal effect on low testosterone is the fact that treating men with thyroid medications can actually boost their testosterone back to normal. [1][2] One study found that giving hypothryroid hypogonadal men thyroxine (T4) almost doubled their free testosterone levels! [3]
4. More Than Doubling Total Testosterone. Normally one will not get a huge boost in testosterone from fixing his hypothyroidism. However, huge gains are possible as evidence by a case study of one man with both severe hypothyroidism and hypogonadism. [4] This individual was able to increase his total testosterone by 150% just my standard thyroid treatment. His testosterone was still pretty low – in the low 400’s – but it was an impressive gain nonetheless.
