Low and High Testosterone Symptoms
What are the signs and symptoms of low (or high)
Male Testosterone Levels? For example, just
what does low testosterone affect in us guys? The most accurate answer is
"everything"! Low testosterone effects almost every major
system in the male
body and has very serious long term health consequences, all of which I outline
Before I explain more, I have noticed that over half of all you reading this will have already had a
testosterone lab reading taken and are wondering if your number is okay.
(Read this link on
testosterone levels for more detailed information.) I
mention this because some of you have had a doctor tell you that a very low
number is okay. The
standard range that the labs and doctors will give you for total testosterone is
241-847 ng/dl. But trust me - if you are in the 241-399 range, you will almost for sure be
experiencing various symptoms of low testosterone.
There are some guys who
do okay in the 400's, but even in the 400's most males will be struggling a
little. Again, it is possible for a male to have, for example, total testosterone of 450 ng/dl
and feel just as good as a guy that has total testosterone of 700 ng/dl, but this is unlikely.
The same goes for high testosterone as well.

There are several things to keep in mind when analyzing the number:
1) Your symptoms of low or high testosterone are just as important as the
number itself. Please, please read the symptoms below for signs of low
testosterone and signs of high testosterone. Science has just recently
found out how all-important testosterone is for us males.
2) Don't trust one lab reading. Testosterone readings can vary,
but keep this in mind: low testosterone levels can be deadly long term. You
must take your testosterone levels dead serious. (
NOTE: Please read my
to Increase Your Testosterone Naturally for more nformation.)
3) Your estradiol, the most abundant form of
Estrogen, reading is just as
important as your testosterone reading. The normal range is usually 13-54
pg/ml, but what is really critical is the ratio of testosterone to estrogen.
Young males have ratios of 30, 40, 50, etc. You could have a healthy total
testosterone reading of 500, but if your estrogen is 50, you are probably going
to be struggling. Read this link on
Estrogen to understand why.
4) Free Testosterone is just as critical as total testosterone. Free
testosterone is generally expressed as a percentage of your total testosterone
and the standard range is 1.6%-2.9%. Yes, that means only about 2% of your
testosterone is really "free" to do all the things us males need testosterone to
do. You want this above 2.0% for sure.
You should therefore read my page on How
to Control and Manage Free Testosterone.
Low Testosterone Symptoms
The symptoms of low testosterone usually creep up upon you slowly and quitely.
Because of this, many guys ignore their low testosterone symptoms for months or
even years: they literally get used to to feeling lousy and functioning
poorly. But that can be a deadly mistake as I'll show below.
The symptoms of low testosterone can also fool a guy because they are so
ubiquitous. By that I mean that testosterone affects EVERYTHING in the
male. It affects our brain, our libido, our muscles, our blood - the list goes
on and on. Of course, the number one thing in most guys' mind is how it affects
their sex life. Low testosterone affects both libido and erectile strength
to varying degrees and that obviously isn't too good for the ol' sex life.
However, common symptoms also include depression, mental fogginess/fuzziness, difficulty concentrating,
anxiety, loss of muscle, increased weight gain, decreased facial hair and a
general feeling of not caring about anything. When you are low on
testosterone, you often just don't care about anything - you just "exist".
Pleasure and desire can be greatly decreased greatly affecting your career and
Fortunatly, verification of
low testosterone levels is then rather
simple: you go to the doctor and he does some blood work and three days later
you get the results. The Official Level for low testosterone level is an abyssmal
and often doctors
won't diagnose you as low testosterone (b>hypogonadal)) unless you are at or below this incredibly low figure.
But you need to realize that 260 is
VERY low testosterone and is an outdated and arbitrary statistical figure. In all reality, if you're below about
350, you will probably begin to experience long term health issues and many
of the symptoms that I list below. I am mentioning this, because I get letters
from guys all the time saying that their doctors say it is okay for them to have
testosterone levels in the 200's or low 300's. If that is your situation, I
encourage you to discuss the deadly long term health consequences of low
testosterone that I list below for you.
If you get down to the 200's,
there's a good chance that you won't care about much of anything in your life,
especially sex. This was verified in a study  from China where guys with low testosterone (average=268)
were compared with guys with normal (average=553) levels. Read the typical
symptoms for the poor guys on the low side: "89 percent of
the subjects suffering from low testosterone reported a lack of energy; 79 percent reported erectile dysfunction; 70 percent reported a
loss of pubic hair; and 66 percent reported a decrease in sexual endurance..
From this data, the researchers concluded that low levels of testosterone are
directly related to both advanced age and diminished sex drive."
Sadly enough, a lot of guys won't do anything about low testosterone until they
begin to experience signs and symptoms of impotence and erectile dysfunction. Penile
muscles are packed with androgen receptors, i.e. your penis needs testosterone or
the penile muscles literally atrophy. That means you cannot trap the blood necessary
for an erection leading to poor performance and the ensuing performance anxiety
This is try for both young and old by the way. One study found that low
testosterone is a factor in 20 percent of young men under 30 with erectile
problems. I find it to be an extremely common issue in the letters that I
get from the younger guys. 
Kegel Exercises can help you get these muscles back in
shape, but you still need the testosterone for your brain and long term health. (You also need lots of
Nitric Oxide and good blood flow. See the
Erection Repair Guide and the Erection
Supplementation Guide for details.)
By the way, one recent Boston University
School of Medicine study discovered
that testosterone actually guards and protects the penile nerve fibers.  In
other words, at least in rats, low testosterone levels means nerve deterioration.
No wonder low testosterone is so related to erectile dysfunction!
Low Testosterone: The Long Term Health Consequences
So if the doc tells you a reading of 350 is fine, you can always do
the reverse of what I tell you on this site: for a few days
prior to your blood test try to decrease
your testosterone: eat a high fiber, low fat diet with little
saturated fat all the while you're overtraining on little sleep.
That ought to whack a good 30% off your
score. But a better solution is to just get a new doctor.
You want to work with someone who is
not living in 80's as far as medical knowledge and practice.
Why do I say that? Because the symptoms of low testosterone are just plain dangerous. Low testosterone is associated with heart
disease, depression , Metabolic Syndrome , diabetes , cognitive disorders and even osteoporosis. It is no
exaggeration to say that low testosterone is the Kiss of Death for all you male
homo sapiens out there. A 2007
study found that low testosterone was associated with increased risk of death
from heart disease, cancer and all causes.  So please, please do NOT accept your doctor's opinion that testosterone
in the 200's or 300's is okay.
One of the reasons that low testosterone is so deadly is that it somehow effects
all the major cardiovascular markers. One recent large scale
epidemiological study found that low testosterone men, < 250, were 1) fatter,
2) had lower HDL, 3) higher triglycerides, 4) higher blood pressure and 5)
higher blood glucose.  That is a deadly combination! The low
testosterone men were tracked over 18 years and it was found that they had a
40% higher death rate from all causes!
Low testosterone will also often put your
relationships and career at jeopardy as well, because testosterone so strongly effects the male
brain. For example, supplemental testosterone can aid certain
types of memory in men. Working memory, which allows you to manipulate information
over brief periods of time in order to make a response, improves. Verbal memory,
which helps you recall lists of words, and spatial memory, which helps you navigate
a route, also benefit. 
(By the way, I cover many ways that science has found to re-build your
brain on this site. See
this link on the Brain for more information about how to build
your cognition and memory no matter what your age.)
I should also mention that low testosterone is associated with increased risk of Alzheimer's
Disease (AD) as
well! How's that for an ugly symptom? The well-known Baltimore Longitudinal Study showed this strong
correlation do dementia. Researchers are still trying to figure out why, but studies of rat brain cells found that the hormone limits the production
of beta-amyloid peptides. These sticky protein fragments, thought to be a prime
contributor to Alzheimer's, build up into small, round deposits and clog the brains of people
with the disease.
The hormone also may help ward off AD by directly preventing brain cell death.
In studies, researchers manipulated human brain cells, sending them on a course
to die. Adding doses of testosterone, however, limited the [brain] cell death."
No wonder that low testosterone leads to depression, feeling like you're "in a fog"
and difficulties concentrating! Your libido
will probably sag and you may find that you really don't care about much of
anything. Low testosterone can even easily lead to anxiety and
depression as well. Remember: these are not just
symptoms - low testosterone effects your brain chemistry at its core.
On top of all that low testosterone men tend to be slightly sleep deprived
because research has shown that low testosterone leads to poor quality sleep.
 This is probably due to the extra adiposity (body fat) that comes from
decreased muscle mass. You need your testosterone to burn that fat off
I should also mention, though, that one recent study found that many males with
low testosterone, defined as < 300, were asymptomatic. In fact, that study found
that almost 50% of males in the 50+ age range had no significant symptoms with
low testosterone.  In other words, there is a significant percentage of you
and your friends out there, generally in the 40+ age range, that are walking
around with low testosterone and are actually not even exhibiting symptoms. That
is why I would advise any middle-aged and beyond guy to occasionally get his
testosterone checked even if he's "feeling pretty good".
The bottom line is that you need your testosterone. It's the heart and
soul of the male physiology and psychology. But I thought it was dangerous to boost your testosterone
you may ask? (Please read
my link on the Prostate to find how to greatly improve your odds against Prostate
Cancer.) Remember: I'm not a doctor, so you should talk to yours. But I want to point out that decades of studies have shown time
and again that there is no link between prostate cancer and testosterone supplementation.
Testosterone is a natural substance INCREDIBLY important to your male body and mind.
If your levels are low, testosterone supplementation is not abuse: it's
simply getting your hormone levels back in line. Remember: your goal is not to be
Barry Bonds with sky high testosterone levels so you can compete with other ten
million dollar elite athletes. You are simply trying to get your tissue levels back
reasonably close to the days of your youth. All these nasty symptoms can
go away in a day if you get rid of your low testosterone.
Again, what is really dangerous is to NOT
boost your testosterone. Low testosterone symptoms are not
just symptoms: low testosterone levels will literally kill you (and before
that probably make you miserable and impotent). So, please, get to the doctor and get tested if you
have any doubt. (And don't be afraid to get tested again: testosterone
readings can sometimes be off.)
Low Testosterone Solutions
So what do you do if you find you are low testosterone? Well, it depends on
your reading. If you're just a little low, say in the 400's, you can try to
raise your testosterone naturally. I cover many ways on this site to boost
testosterone, including Sex,
High Testosterone Diet,
Sleep and your
I also write about some
of the common things that attack your testosterone such as
Testosterone Lowerers, being Overweight,
Overtraining and even
You can put all these together and sometimes
boost your testosterone 30% or more.
However, if you are in the low 300's or 200's consistently, then I recommend
that you read my HRT (Testosterone Therapy) link. You need to double or triple your testosterone
levels and you're probably not going to do that through lifestyle changes.
But do what you have to do. Don't leave yourself exposed to a lifetime of
heart disease, depression, anxiety, diabetes, metabolic syndrome and other
associated with low testosterone!
By the way, it is possible that some of your issues are from
