The Hypothalamus and Your Hormones
What is the most important gland in the body? The testes, right? No
way! Not even the all-important testes can hold a candle to the
hypothalamus. The testes get the glory, but the hypothalamus sits back in
the shadows as the real master of all we hold dear as a male. As we'll
show below, the hypothalamus governs just about everything that is worth
Most men think of the hypothalmus as a structure that lies deep within the brain
behind the blood-brain barrier. Well, that simply is not true. It is
true that it is "tucked away" with the brain, but it is mostly in front of the
blood brain barrier and has considerable exposure to chemicals and toxins.
The most infamous of the toxins that can damage the hypothalamus are the
so-called excitotoxins, MSG and aspartame for example. Excitotoxins are abundant, and more often that not hidden in most modern wheys
and processed foods. Have you seen autolyzed yeast extract or hydrolyzed
protein in an ingredient list? You can bet it's packed with excitotoxins.
Many health-conscious men expose their hypothalamus to multigram dosages of free
glutamine simply out of ignorance.
As I document in my link on Excitotoxins and Testosterone
, this is a really BAD idea. These dosages are likely slowly damaging
hypothalmic tissues and it's no wonder
that probably 95% of low T men on the Peak Testosterone Forum
hypogonadism: they have been unknowingly hammering their hypothalamus for
years with small but significan dosages of these toxins.<
So I am hoping in this thread to encourage men to take care of this all-important gland and also
point out some very interesting research that shows that the hypothalamus' importance actually extends far beyond
just it's hormone-boosting properties: it appears to be a literal fountain of youth.
Consider these functions of the hypothalamus:

Natural Versus Testosterone Therapy
1. Testosterone. Testosterone production does NOT begin with the
testes: it begins with the hypothalamus. They hypothalamus sends a
signaling molecule, GnRH to the pituitary, which then triggers the release of LH
(Leutinizing Hormone), which in turn triggers the testes to create testosterone.
The testes are actually third anything. And, yes, anything that damages or injures the hypothalamus will
likely affect testosterone
production and the whole chain of steroid hormones in men.
Furthermore, most hypogonadal men are secondary, meaning that men with hypogonadism
have an issue with either the pituitary or the hypothalamus.
I base that on the fact that the great majority of low testosterone men on the Peak Testosterone Forum are secondary
and have an issue
with either the pituitary or the hypothalamus. The fact that they are secondary is
shown by the fact that Clomid works on so many of them and that their LH
(leutinizing hormone) levels are low or lowish. When a man has primary
hypogonadism, usually his LH is on the high side, because it is "working
overtime" to try to stimulate the testes into a more normal testosterone output.
The primary points are this: the hypothalamus is ground zero for
production of your testosterone and other steroid hormones (DHT and the
estrogens) and there is evidence that the hypothalamus is often the problem area for
most low testosterone men.
2. Thyroid Function. Many, many men are hypothyroid.
Hypothyroidism affects general health, sexual function, energy levels and can
lower testosterone. And, very analagous to the situation with
testosterone, the hypothalamus is starting point for thyroid hormone production.
It secretes thyrotropin-releasing hormone (TRH) which is turn triggers the more
well-known TSH that is released by the pituitary and monitored by many doctors.
Thus, hypothalmic dysfunction can affect thyroid function in a very similar way
to how it can downgrade testicular function. (For some research showing
this, see #22 on my link How to Increase
3. Insulin Sensitivity. What does a huge percentage of heart disease
and erectile dysfunction have in common? Insulin resistance.
Prediabetes and diabetes are rempant here in the U.S. and probably affect about
half of adults over the age of 40. And how these conditions take a toll on our sex life.
(See these Links on Diabetes and Metabolic Syndrome
for more information.) Most men know that
the pancreas houses the beta cells that manufacture insulin and that diet and
exericse play a major role in controlling blood glucose and insulin levels.
However, what few men realize is that the hypothalamus plays just as pivotal of
a role in
As is true of so many things, the region above your neck is the master control
center for most of your bodily functions, inclduing insulin sensitivity. Researchers showed this recently
in an animal study where they fed the animals a high fat diet. Why did
they feed them a high fat diet? Because, as I often point out, a high fat
diet induces insulin resistance. This led to "a decrease in
insulin-induced signaling and an increase in activation of a protein known as
SK6 in the hypothalamus." 
Further evidence is shown by the fact that excitotoxins, which damage the
hypothalamus, make animals fat in a number of research studies.. Excitotoxins
accelerate weight gain in other ways as well by the way: they have been
shown in several studies to stimulate the pancreas. Plus, diet drinks, most
of which are packed with excitotoxins, also have been shown in study after study
to lead to weight gain.  (The reasons for this are a little different,
however, than hypothalmuc damage.)
4. Aging. Where is the Holy Grail of human aging? Scientists
recently found that it lies in the hypothalamus. Already in animals they
have increased longevity by 20% simply by controlling NF-kB within the
hypothalamus.  It turns out that FN-kB is literally a dial that controls
aging and it is all due to the fact that it acts on the hypothalamus.
Some experts think that life span can be extended somewhat in humans through this
as well. And, althought it hasn't been tested in primates yet, I don't think
anyone doubts that the hypothalamus is ground zero to human aging. And no
wonder: it controls blood sugar/insulin control and our key hormones.
It's hard to find anything more important than that, eh?
So there are four very good reasons to protect your hypothalamus. Keep in
science may even develop a reasonable anti-aging strategy that involves control of the
hypothalamus in the next few decades. Do you want to be left out of the party because your hypothalmic
tissue is lesioned and unresponsive??
