LOW TESTOSTERONE? UNDERSTANDING ITS MANY POTENTIAL CAUSES CAN HELP LEAD TO LONG LASTING SOLUTIONS

“Commercials don’t mention a 2009 study in the New England Journal of Medicine wherein a group of men on testosterone replacement therapy had more than four times the number of cardiovascular problems — so many that the study had to be halted.  They also don’t make clear how risky exposure to testosterone gel is for others — female partners, children, even pets. The gel is actually notorious for transferring to others.

It can cause excess hair to grow on women’s faces and arms, deepen their voices, interrupt menstruation, and make them anxious and irritable. In children, exposure to testosterone gels and creams can cause premature puberty and aggression. And in pets, it can cause aggressive behavior and enlargement of the genitalia.” From John-Manuel Andoite’s article in the Atlantic called Should the Modern Man Be Taking Testosterone?

“Consumer advocate Dr Sidney Wolfe of Public Citizen says testosterone prescriptions in the US are 17 times higher per population than in the UK overall. And alarmingly, a fifth of those were for the non specific symptom of ‘fatigue’ and up to 9% were for men who had normal or high levels already. Some are given prescriptions without even having their levels checked. In 2014, Public Citizen actually filed a petition with the US Food and Drug Administration (FDA) requesting a strong health warning on all drugs containing testosterone.”  From Ann Robinson’s article in The Guardian, Testosterone Therapy: Hope or Hype?

If you are a male, testosterone is awesome stuff.  Exposure to the two month old fetus helps form the male sex organs.  At puberty, production explodes, causing growth and maturation of said sex organs, along with secondary male characteristics such as deepened voice, body hair, beard, etc.  Testosterone is part of what helps provide the male with self-esteem and their naturally-competitive nature.

It builds lean body mass (muscle), while increasing BMR (Basal Metabolic Rate) and preventing the deposition of fat.  It’s also important for the formation of RBC’s (red blood cells).  A “normal” amount should be above 300ng/dL (nanograms per deciliter), with an average of 7 mg being produced by the testes each day.  I put the word normal in quotes simply because depending on one’s age, the range is 300 to 1,100 — a crazy amount of variation on what’s considered “normal” (550 is considered the average “functional” value).

The latest research says that about 25% of our adult male population has LOW TESTOSTERONE, with more of them obviously coming as they get older.  However, due to any number of factors — many of which we will discuss today — there is a growing segment of the young adult male population who is dealing with Low T as well — an issue that is intimately tied to the precipitous decline in sperm counts of the males in Westernized countries (HERE).

The problem is that in similar fashion to what we discussed when we talked about the male menopause known as ANDROPAUSE is that an entire industry has grown up around diagnosing and treating low testosterone; most of it having to do with male HRT — Hormone Replacement Therapy — in the form of supplemental prescription testosterone.  While this is certainly a viable option in some cases (emphasis on “some”), it should always be the last option.  Why?   Follow along as I show you.  As a side note; if this problem pertains to you, even if you are young, make sure to read the post on Andropause.

When you take exogenous testosterone, your body senses the high levels and in similar fashion to a thermostat, shuts down endogenous production (testosterone made by your own testicles) even further. 

This is why, among numerous other health issues, the longer you are on supplemental testosterone, the more atrophy of your own testicles, and the greater the problem of ever getting your own production restarted and on track (bodybuilders and athletes using testosterone as a PED will often use the female hormone HCG (an LH analog) followed by a drug used to treat infertility in women, in order to try and restart endogenous production — stick with me and you’ll soon understand why they do this.

I would never say there is not a time or place to replace hormones (HERE is my article on female HRT and menopause), but it’s rarely the best case, and should never be done without doing things to deal with underlying causes.   Otherwise, you run the risk of saturating hormone receptors and causing hormone “resistance” (think INSULIN RESISTANCE here, although there are several genetic forms of Testosterone Resistance such as Androgen Resistance and Androgen Insensitivity Syndrome). 

In other words, the natural progression — particularly if you are young — is that it takes more and more of the hormone to get the same result, eventually hitting the point where there is diminished hormone function.

TESTOSTERONE PRODUCTION DIAGRAMS

According to Wikipedia, Hypogonadism, in terms of males, is defined as…

Diminished functional activity of the gonads / testes that may result in diminished sex hormone biosynthesis. Low androgen (testosterone) levels are referred to as hypoandrogenism. Other hormones produced by the gonads that hypogonadism can decrease include progesterone, DHEA, anti-Müllerian hormone, activin, and inhibin. Spermatogenesis may be impaired by hypogonadism, which, depending on the degree of severity, may result in partial or complete infertility.

Not only can Hypogonadism cause INFERTILITY, but not surprisingly it can cause SEXUAL DYSFUNCTION as well.  But I am getting ahead of myself.  If you really want to understand what causes Low Testosterone levels — particularly in the younger crowd — as well as grasp the differences between primary and secondary hypogonadism, you are going to have to understand a bit of neurology / endocrinology. 

Hang in there, however, because it’s not as bad as it sounds.  Understanding is important because a failure to grasp the basics of the following diagrams is probably a deal-breaker as far as understanding and solving your Low T issue is concerned.  Let’s start with cholesterol.

Why are CHOLESTEROL and Vitamin D so important as far as sex hormones are concerned — in this case testosterone?  Namely because both testosterone and vitamin D are synthesized from cholesterol via an important intermediate called pregnenolone (remember pregnenolone because it will come up again momentarily).

The brilliant Chris Masterjohn puts it this way.  “Since cholesterol is a precursor to vitamin D, inhibiting the synthesis of cholesterol will also inhibit the synthesis of vitamin D. Since sunlight is required to turn cholesterol into vitamin D, avoiding the sun will likewise undermine our ability to synthesize vitamin D. And since vitamin D-rich foods are also rich in cholesterol, low-cholesterol diets are inherently deficient in vitamin D.”  But the importance of cholesterol does not stop there.

The flow chart diagram below not only shows (along with the proper enzymes) how cholesterol also happens to be converted into testosterone, but into estrogen as well (by the aromatase enzyme). What does all this really mean? 

It means that even though numerous studies have shown that too much cholesterol (high cholesterol) has a negative impact on sex hormones, not surprisingly, so does low cholesterol, which is increasingly possible with our INDUSTRY-DRIVEN GUIDELINES on what should be considered normal.  Interestingly, there are studies showing that supplemental testosterone increases cholesterol levels (this is one of its major potential side effects), while other studies show that it normalizes low testosterone.

For instance, a study from April’s issue of Sexual Medicine Reviews (Testosterone Replacement Therapy and Components of the Metabolic Syndrome) concluded that there is indeed, “a plethora of contrasting literature on the efficacy and safety of testosterone replacement therapy….  [which has] the potential to alleviate some of the morbidity associated with hypogonadism and Metabolic Syndrome.”  What exactly is CARDIOMETABOLIC SYNDROME (aka pre-diabetes)?  Just click the link.

However, seventeen authors writing in the February issue of EndoText (The Effect of Endocrine Disorders on Lipids and Lipoproteins) clarified this dichotomy by saying,

“Men with low testosterone levels may have high LDL cholesterol and triglyceride levels and decreased HDL cholesterol levels, although this relationship is confounded by obesity and the metabolic syndrome, a common cause of male hypogonadism. Androgen deprivation therapy results in an increase in LDL cholesterol, triglycerides, and Lp(a) and a decrease in HDL cholesterol. The effect of testosterone replacement therapy on plasma lipids and lipoproteins is modest and variable but high dose androgen therapy used by athletes can markedly decrease HDL cholesterol and also reduce Lp(a) levels.” 

In essence, supplemental testosterone is more likely than not to foul up cholesterol levels; and while it might provide a “modest” improvement, the higher the dose (think steroids here) the more screwed up the lipid / cholesterol profiles are likely to be.  Think this isn’t a big deal?  Let’s briefly look at some studies.

Just a few months ago the Journal of Endocrinological Investigation (Influence of Vitamin D Levels on the Cardiovascular Profile of Hypogonadal Men) concluded that, “Our work shows the influence of vitamin D on cardiovascular profile in male hypogonadism. This effect seems to be more relevant in non-diabetic subjects. If these data were to be confirmed, vitamin D assessment might become mandatory in the clinical evaluation of cardiovascular profile in male hypogonadism.” 

Back in Y2K, a study published in Metabolism (Effects of Simvastatin and Pravastatin on Gonadal Function in Male Hypercholesterolemic Patients) speculated that, “Inhibition of cholesterol biosynthesis by hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase inhibitors could, in theory, adversely affect male gonadal function because cholesterol is a precursor of steroid hormones.”  A study published earlier this year in Endocrine Practice confirmed this when they concluded, “Long-term simvastatin intake reduces serum testosterone, estradiol, and progesterone levels in male rats.” 

And just last month the Journal of Sexual Medicine published a study (Low Plasma Testosterone Is Associated With Elevated Cardiovascular Disease Biomarkers) that concluded, “Men with low plasma T levels exhibit increases in cardiovascuar risk markers, consistent with a potential increased risk of cardiovascualr disease.”  While this is certainly not a shocker, what if I told you that this issue is potentially related to AUTISM? 

Just two short months ago, the journal Autism Research published a study called The Role of Cholesterol Metabolism and Various Steroid Abnormalities in Autism Spectrum Disorders: A Hypothesis Paper in which they concluded (cherry picked),

“Testosterone is a steroid hormone which is directly metabolized from cholesterol.  Based on evidence from the relevant research literature, we present a hypothesis that there may be a link between cholesterol, cortisol, testosterone, estrogens, progesterone, and vitamin D in autism spectrum disorder (ASD).  ASD is diagnosed much more often in boys than in girls and there has long been speculation and controversy about the role of “the male brain” and sex hormones (particularly testosterone) in the pathogenetic chain of events leading to the clinical disorder and to “autistic traits”.“

I could go on and on here (including THESE STUDIES on statins and sexual dysfunction / infertility) but I realize that time is running short.  Even though I wrote the article in the link above over three years ago, realize that it was late last year that the Journal of Clinical Lipidology (The Effects of Statin Treatment on Adrenal and Sexual Function and Nitric Oxide Levels in Hypercholesterolemic Male Patients Treated with a Statin) concluded that, “Erectile dysfunction complaints among men treated with a statin are not uncommon.” 

Bottom line, while statin drugs certainly help lower cholesterol levels, they do nothing to deal with helping the body return to HOMEOSTASIS.

Some have referred to the production of sex hormones as more complicated than a “RUBE GOLDBERG CONTRAPTION“.  Hopefully these diagrams above, along with this short explanation, will help simplify things.  Gonadotropin-releasing hormone (GnRH) is exactly what it sounds like — a hormone that causes the release of the gonadotropins — follicle-stimulating hormone (FSH) and luteinizing hormone (LH) — from the anterior pituitary. 

FSH stimulates Sertoli Cells in the testicles to produce sperm, and LH stimulates Leydig Cells in the testicles to produce testosterone.  As you can see from the arrows and the + symbols (upregulation) or – symbols (downregulation), in a perfect world; if your body senses Low T it simply tells the hypothalamus to release more GnRH, which starts the process over again until testosterone levels are high enough.

The testosterone enters the body in it’s “free” state, but is quickly bound — or about 98% is bound, either by either Sex Hormone Binding Globulin (SHBG — about 60%) or albumin; about 38%.  Because the bond that holds albumin to testosterone is much weaker that that between testosterone and SHBG, it is sometimes considered an easier-accessed form testosterone). 

In order for testosterone to be used by the body, it must become unbound again or free, and after this it must hook up with testosterone receptors.  Thus, in similar fashion to insulin, we want good sensitivity (as opposed to “resistance” —- INSULIN RESISTANCE).  Men who use copious amounts of exogenous testosterone (i.e. STEROID USERS) can develop “Testosterone Resistance” in much the same manner.

Simple, isn’t it?  It is until things start to go haywire.  And when things go haywire, men end up with Low T.  As you may be starting to realize, there are lot of ways to get there from here.  What I want to do is cover a few of them in relationship to the diagrams we just looked at.  In order to do that we are going to go right down the line and look at what happens when the points we just discussed go awry.  For instance….

LEVELS MIGHT NOT BE UP TO SNUFF

Why is knowing what low testosterone looks like such a big deal?  Take a look at the conclusions of this ten year old study from the Journal of Clinical Endocrinology and Metabolism (Decline in Male Testosterone and Sex Hormone Binding Globulin Serum Levels in Danish Population Surveys).

Revealing something that others have shown as well, the authors concluded that testosterone levels have dropped precipitously over the past decades.  “In addition to this expected age effect [older dudes having less testosterone than younger dudes], significant trends in testosterone and SHBG serum levels were observed in age-matched men with lower levels in the more recently born/studied men.“

As crazy as it might actually seem, there is a group of physicians led by Dr. Malcom Caruthers, a professor in the Alzheimer’s and Aging Department of Edith Cowan Unversity in Australia, as well as President of the Society for the Study of Androgen Deficiency (the Andropause Society), who believe that the amount of testosterone is not the issue as much as one’s level of resistance or sensitivity to the hormone. 

Thinking of testosterone in terms of insulin, this makes sense.  No one wants massive levels of insulin in their bloodstream as this leads to all sorts of problems (including receptor saturation and subsequent resistance).  Instead, they want low amounts of insulin, with a high degree of receptor-sensitivity to it.  More on this topic later, but for now, let’s look at some of the causes / symptoms of Low T (these are in no particular order).

WHAT IT TAKES TO RAISE LOW TESTOSTERONE LEVELS WITHOUT RESORTING TO SUPPLEMENTAL TESTOSTERONE

There are enough articles and studies on what it takes to increase your testosterone levels that at the very best, it can be extremely confusing.  The world wide web abounds with both information and sales pitches for their products — most of which are complete and total crap.  Honestly, for most of you if you simply follow some basic health premises, you’ll see some great changes.

Be aware that some of you might require work with a FUNCTIONAL MEDICINE SPECIALIST of some sort to get this thing sorted out.  Also be aware that there are many many practitioners jumping on this bandwagon due to its popularity.   In other words, watch out for “FUNCTIONAL MEDICINE LITE“.
