do you know your penis?
- why do I get erections while sleeping? -
what is the reason for my morning erection
Definition, causes, and problems
with morning erections
Many young men, and even some older ones who haven�t found the right
people to ask, are curious about morning erections. Most men have the
experience, with some regularity, of waking up in the morning with an
erection.
What Is A Morning Erection?
Morning erections, colloquially referred to as "morning
wood" and scientifically defined as nocturnal penile tumescence (NPT)
are a healthy and normal physiological response that most men
experience. Morning erections would be better described as the tail
end of a series of nighttime erections, as they are just the last
erection in a series.
On average a healthy male will have between three and five erections
in a full night sleep, with each erection lasting between 25 -35
minutes.
Causes of Morning Erections
It is a common myth that morning erections are caused by a full
bladder.
This is untrue. While the reason for morning erections is unknown, we
do know that the erections are closely associated with REM sleep (the
time in the night when you dream and brain activity changes). These
erections are also associated with an increase in heart rate. It
isn�t known for sure if the erections are a result of the other
physiological changes, more research is required. One guess is that
these erections are the bodies way of making sure everything is in
good working order.
Lack of morning erections
Early research on morning erections did not find a difference in the
morning erections of older men when compared to those of younger men.
More recent research has shown a gradual decline in morning erections
(some show just a decrease in the rigidity and length of time of an
erection and not the frequency of getting erections).
One of the reason morning erections attracted the interest of
researchers was as a tool to rule out physical causes of erectile
dysfunction. If a man cannot get an erection to his satisfaction
during sexual activities one of the first things a doctor will
determine is whether or not he is getting full erections during the
night and in the morning.
If a lack of morning erections is accompanied by a lack of overall
erections it suggests a physical over a psychological cause. If you
are concerned about a noticeable change in your morning erections it's
something you may want to talk about with your doctor. However there
are a variety of other factors that influence morning erections
(including length and quality of sleep) and a change in morning
erections doesn't always indicate a serious problem.
Erectile dysfunction medications and morning erections
Medications used for the treatment of erectile dysfunction (ED)
including sildenafil (Viagra) and tadalafil (Cialis), can have an
impact on morning erections. Both medications, if taken the night
before prior to sexual activities, can result in morning erections,
although morning erections occur more often when tadalafil is used.
Of course there is no reason to take a medication simply to get a
morning erection, as morning erections, while they may be related to
overall erectile function are not necessarily a total indicator of
function or dysfunction.
