Testosterone and Erectile Dysfunction
Viagra and Cialis proved once and for all that testosterone has little or
nothing to do with erectile dysfunction, right? You just take a little
pill and then everything works out in the bedroom again, correct?
Wrong! This has proven decidedly NOT to be the case and one (of many) key
reasons is that taking Viagra or Cialis does not address the key issue of low
testosterone that often plagues middle-aged males. Yes, Viagra and Cialis
will boost endogenous nitric oxide levels, but that simply isn't enough when a
man does not have satisfactory baseline testosterone levels.
NOTE: Viagra and Cialis often do not work for other key reasons as well.

Natural Versus Testosterone Therapy
Below are several critical ways that low testosterone sabotages your erections:
1. Nitric Oxide. Viagra affects the NOS (Nitric Oxide Synthase) enzyme,
allowing nitric oxide to essentially persist longer. However, what some
researchers and physicians seemed to have forgotten is that NOS is strongly
affected by testosterone. For example, castrated rats lose about half of their
penile NOS activity.  And the only way to restore the rat's "hardness
factor?" Give them testosterone!  You are definitely swimming upstream
with low testosterone.
2. Internal Penile Atrophy. Nerves, connective tissue and other internal
structures within the penis begin to atrophy and harden in a low testosterone
environment. If this goes on too long, it can result in
Venous Leakage, a
condition where blood leaks out of the penis as quickly as it goes in, making
erections less and less firm as time goes on.
3. Pelvic Floor Musculature. The muscles at the base of penis are packed
with androgen receptors. These muscles naturally wither without adequate
testosterone levels. This is yet another
reason why Kegels can often help men.
4. Morning Erections. Morning erections are critical for penile health and experts believe that the lack of them can contribute to erectile dysfunction. Researchers believe that the internal tissues are oxygenated during this
critical time while you are sleeping. Reseachers have found that if your
testosterone gets low enough, morning erections can diminish or even vanish
5. Libido. It is no secret that testosterone and libido go
together.  I cannot tell you the number of emails that I have received from
men who have lost interest in sex altogether and, of course, they almost always
have low testosterone levels. Low libido can lead to many erectile issues, since it can
strain relationships, dulls desire and leads to decreased sexual activity and
6. Mood and Depression. Testosterone has a monumental effect
on the male brain and many studies have shown that low levels lead to depressive
(and other related) symptoms.  This can create a vicious cycle as
depression, in turn, can lower testosterone.
So, as always, the bottom line is get tested if you have
any Symptoms of Low
Testosterone and/or symptoms of erectile dysfunction - one root cause could definitely be
hormonal. And here's a teaser for my new book as well: if you want to know the exact
levels at which testosterone and erectile dysfunction collide, including
surrounding issues such as morning erections and venous leakage, please check out
